OSH Code 2020 Compliance Guide

On Tuesday, 9 June 2026, the HR head of the 220-person electrical equipment manufacturer in Pune sat in the conference room with three things in front of her: a dangerous-occurrence report dated the previous Friday, a Section 43 consent file for fourteen women workers being inducted into the second-line evening shift on Monday next, and an inter-state migrant intake file for fifteen workers arriving from West Bengal on the morning train for the monsoon-period inventory run. May's payroll had cleared on the new salary structure, June's was due at the end of the week, and the new evening shift, scheduled to launch on Monday 15 June, sat four working days away.

The dangerous-occurrence report described a high-pressure hydraulic hose that had burst on the press shop floor at 3:42 PM on Friday, 5 June. No worker had been injured. The hose had been clamped within minutes, the area cordoned, the maintenance team had replaced the hose by close of shift, and the press had restarted on the second-shift cycle the following Monday. Section 11 of the Occupational Safety, Health and Working Conditions Code, 2020 carries the notification clock for events of this kind: any dangerous occurrence at the workplace, whether or not anyone is injured, is notified to the prescribed authority in the form and within the timeline the appropriate Government has notified. The maintenance log sat in one binder; the Section 11 notification draft sat in another, ready to file.

A second binder, the Section 43 consent file, held the second-line shift induction. Fourteen women workers drawn from the existing operator pool would begin a 2 PM to 11 PM cadence on Monday 15 June, the new shift the works manager's letter of 18 May had proposed and the Section 40 21-day notice covered in Industrial Relations Code 2020 Guide had cleared. Working past 7 PM brought the OSH Code's Section 43 conditions into play: written consent of every woman worker, documented transport home and back to a safe drop point, verified lighting at the workplace and along the routes, security staffing including female personnel where prescribed, rest facilities on site, and any safety measures notified by the Maharashtra labour department. The HR head's file held all six items, by row, against each of the fourteen names.

A third binder ran the inter-state migrant intake. Fifteen workers from a labour contractor in Howrah, engaged on three-month written contracts at the operator wage band, would arrive at Pune Junction at 6:50 AM on Wednesday 10 June. At 192 workers plus the incoming 15 inter-state migrants, the Section 59 threshold of 10 or more inter-state migrant workers employed in the preceding 12 months was cleared. Sections 59 to 65 of the OSH Code attached on day one of the engagement: equal access to working conditions under Section 60, an employer-paid lump-sum journey allowance once a year under Section 61, public-distribution-system portability across the State of origin and the State of employment under Section 62, and accident reporting to next of kin and to the State of origin where the worker came from. Operator wages, the journey allowance budget, and the Maharashtra labour department's prescribed documentation format for ISMW intake all sat on the file.

The Wage Code covered in Code on Wages 2019 Guide was paid in arithmetic and audited in registers. The IR Code covered in Industrial Relations Code 2020 Guide was paid in clocks. The OSH Code is paid in conditions, and the conditions are read on the floor. Each of the four Codes asks for something different from the same establishment.

In force from 21 November 2025 by Gazette Notification S.O. 5321(E), the OSH Code's substantive duties have applied since the commencement date. The Code is the largest of the four by scope, consolidating thirteen older Acts: Factories 1948, Plantations Labour 1951, Mines 1952, the Working Journalists Acts of 1955 and 1958, Motor Transport Workers 1961, Beedi and Cigar Workers 1966, Contract Labour 1970, Sales Promotion Employees 1976, Inter-State Migrant Workmen 1979, Cine-Workers 1981, Dock Workers 1986, and the Building and Other Construction Workers (Regulation of Employment and Conditions of Service) Act 1996. The companion Building and Other Construction Workers' Welfare Cess Act, 1996 is a separate statute and continues in force, with its cess collection feeding welfare schemes that flow through the Code on Social Security. Draft Occupational Safety, Health and Working Conditions (Central) Rules, 2025 were re-published in the Gazette on 30 December 2025 under G.S.R. 934(E); the 45-day public-consultation window closed on 13 February 2026, with the draft taken into consideration on or after 14 February 2026, and final notification was awaited as of 25 April 2026. Almost every duty in the Code sits in the live-and-self-executing first layer of the three-layer rollout from 21 November 2025; the prescribed forms, retention periods, and form numbering for several routine compliance items run on the still-draft 2025 Rules and on saved older-Act notifications under the parallel saving clauses read with Section 6 of the General Clauses Act, 1897, until the final Central Rules notify.

This reference holds the article's body sections, each taken into operation below in the order an Inspector reads an OSH-covered establishment.

Section 3 of the OSH Code requires every establishment in which 10 or more employees are employed to register electronically within 60 days of the Code becoming applicable to it, on the portal prescribed by the appropriate Government. The Chapter II registration trigger uses the broader "employee" count (the count that includes managers, administrators, and high-earning supervisors), even though most welfare and substantive duties later in the Code use the narrower "worker" count under Section 2(1)(zzl). Apply the distinction every time a threshold under the OSH Code is read; the two counts move on different denominators, and the wrong one understates the duty.

An establishment already registered under any earlier central labour Act is deemed registered under the OSH Code, with the registration holder required to intimate the existing registration details to the Registering Officer in the prescribed form and time under Section 3(8). Any subsequent change in the particulars of the establishment, that is the address, the occupier or owner, the nature of work, or the headcount band, is intimated electronically to the Registering Officer within 30 days of the change under Section 3(4). The deemed-registered status carries forward; the change-intimation duty is fresh and recurring.

Factories, mines, contract-labour establishments, and construction sites file an additional electronic notice of commencement or cessation of operations under Section 5 of the Code. The Section 5 notice is a standalone filing distinct from the Section 3 registration; one establishment may carry both, neither, or only the latter, depending on the activity profile. The Pune manufacturer carries both: the Section 3 establishment registration as a deemed-registered factory under the older Factories Act, 1948, with the intimation filed in November 2025 against the prescribed form, and a Section 5 notice for the press shop's commencement of multi-shift operations after the 15 June shift launch.

Three duties attach the moment an employee walks through the gate. They are the three most common first-citation items on an inspection visit, and they apply at the establishment's full universe of employees rather than at the narrower worker count.

An appointment letter to every employee, in the form prescribed by the appropriate Government, sits in Section 6(1)(f) of the Code. Existing employees not previously issued letters were to be issued one within three months of commencement, that is by 21 February 2026. The window closed on that date; an establishment that had not issued retrospective letters by then sits in breach on every uncovered employee. The form prescribed under the still-draft Central Rules carries wage period, nature of work, fixed-term duration where applicable, place of posting, hours of work, and the wage rate among its required fields. Oral engagement is not acceptable under the Code, irrespective of the duration of the engagement.

A free annual health check-up sits in Section 6(1)(c). The duty is rule-bound rather than blanket: it attaches to "such age or such class of employees, in such establishments or class of establishments, as may be prescribed" by the appropriate Government. Practitioner reading of the still-draft Central and applicable State OSH Rules through April 2026 places the typical scope at employees aged 45 and above in factories, mines, plantations, building and construction work, and notified hazardous-process establishments, with sector-specific protocols and forms. The Pune manufacturer has 78 employees aged 45 and above; the FY 2026-27 health check-up schedule, drawn against the panel of empanelled occupational-health centres in Pune, runs across June, July, and August on a rolling basis with two cohorts a week.

A hazard-free workplace sits in Sections 6(1)(a) and 23. Section 23 sets out the minimum working conditions: cleanliness and hygiene, adequate ventilation and lighting, safe drinking water at accessible points, separate latrines for male, female, and transgender workers, effective waste disposal, and prevention of overcrowding and noxious dust or fumes. Sector-specific Rules layer additional duties on top for factories, mines, docks, and construction. The Pune manufacturer's Section 23 audit ran in March 2026 against the still-draft Central Rules' baseline checklist and the Maharashtra Factories Rules, 1963 saved provisions; six items were flagged for remediation (locker-room ventilation, second-floor drinking water station, female-toilet door alignment, two skylight panels in the press shop, an obstructed emergency exit, and the hazardous-substance storage cabinet labelling), all closed before the May payroll cycle.

Section 23 of the OSH Code consolidates the working-conditions baseline that ran under the older Factories Act, Mines Act, and Plantations Labour Act into a single applicable standard for every establishment under the Code. Cleanliness and hygiene runs as a daily practice; ventilation and lighting are verified to adequacy in every working area; safe drinking water is provided at accessible points across the establishment; latrines and urinals are provided separately for male, female, and transgender workers; waste disposal arrangements are effective; and overcrowding is prevented by a minimum cubic-feet-per-worker standard the rules prescribe. The Section 23 baseline runs alongside the Section 24 welfare facilities discussed below; an inspection-day walk-through reads both layers in sequence.

Section 24(1) layers welfare items on top of the baseline. Washing points and bathing facilities (separate for men, women, and transgender workers), sitting arrangements where the work permits sitting, locker rooms for personal belongings, first-aid equipment with trained personnel, and rest or shelter rooms available during shift breaks form the universal welfare floor. Each item is verifiable on inspection, and an inspector reads them in the order in which they sit on the floor, against the prescribed list under the still-draft Central Rules and the saved older-sector rules.

Section 24 of the OSH Code stacks additional welfare facilities at progressively higher headcount rungs. The ladder is the single most useful reference for any HR head reading her own establishment against the Code, and the language matters: some thresholds read "X or more" (the rung is met at the count) and some read "more than X" (the rung is met above the count). The difference between exactly 50 workers and 51 workers can decide whether a crèche is owed.

A drafting nuance bears noting on the crèche. The OSH Code Section 24(3) trigger is "more than fifty workers ordinarily employed," with the crèche provided for children below six years of the establishment's employees. The Code on Social Security Section 67, sitting in the maternity benefit chapter, imposes a separate crèche obligation at "fifty or more employees." Most establishments cross both thresholds together, and the two counts move in step. Where they diverge is the operational margin: a worker-heavy unit at 60 workers and 5 administrators clears the OSH Code threshold without necessarily clearing the SS Code threshold, and an employee-heavy unit at 60 employees of whom 40 are managers and 20 are workers clears only the SS Code threshold. The off-by-one distinction matters at exactly 50: an establishment with exactly 50 workers does not cross the OSH Code "more than 50" trigger, while it does cross the SS Code "fifty or more" trigger. Run the count under both Codes in parallel on every threshold review. PRS Legislative Research has flagged a separate concern on the rule-making side: the Draft CoSS Central Rules, 2025 propose to narrow "fifty or more employees" under Section 67 to "fifty or more women employees", a change of category that arguably exceeds the rule-making power, since the parent provision authorises changing only the number, not the qualifying class. The position will firm up when the final Central Rules notify under the Code.

For the Pune manufacturer, the ladder reads at 192 workers as follows: rest rooms and lunchrooms in place under Section 24(2)(iii) since the older Factories Act regime; canteen running under Section 24(1)(v) (the threshold of 100 workers including contract labour was crossed years ago); crèche running under both Section 24(3) of the OSH Code and Section 67 of the SS Code; no welfare officer or ambulance room obligation triggered, because the establishment sits below the 250-worker and 500-worker rungs. The HR head's facilities file holds the floor plans, the daily inspection sheets, and the running maintenance log for each facility.

Section 25 of the OSH Code caps the daily working hours at 8 hours, with rest intervals and spread-over per the rules. The work-week is capped at six days under Section 26, with one weekly rest day. Overtime at twice the rate of wages sits in Section 27, computed on the wages definition the Code on Wages carries (and the OSH Code mirrors at Section 2(1)(zzj)). The 48-hour weekly trigger sits in the still-draft Central OSH Rules, mirroring the trigger under the Code on Wages and confirmed in the MoLE FAQ of 16 March 2026; the 12-hour spread-over including rest intervals carries through from the saved Factories Act practice and the parallel still-draft Central Wage Rules.

The overtime arithmetic from Code on Wages 2019 Guide applies under the OSH Code in the same form, with the wage base running on the recomputed figure from the 50% rule where the cadre's structure carries an excluded basket above the half-threshold. A worker on a daily wage of ₹600 working three hours of overtime in a day earns ₹1,050 for the day on the same arithmetic the Wage Code's Section 14 carries. The overtime register sits separately from the wage register under Section 33 of the OSH Code, with retention as prescribed in the still-draft Central Rules (the 2020 draft carried five years from the date of the last entry, mirroring the Wage Code's preservation period).

A point on the timings worth flagging: Section 25 does not contain a general "6 AM to 7 PM normal working day" rule. The 6 AM and 7 PM timings appear in the OSH Code only as the trigger in Section 43 for women workers' consent, discussed below. The normal working day's start and end times are at the employer's discretion subject to the daily-hours and weekly-hours caps and the rest-interval and spread-over rules.

Section 32 of the OSH Code sets the leave-with-wages framework for workers. The qualifying threshold is 180 days worked in the calendar year (1 January to 31 December), down from 240 days under the older Factories Act, 1948. Accrual runs at one day of leave for every 20 days worked for adult workers, and at one day for every 15 days worked for adolescent workers and workers below ground in mines. Holidays falling within an availed-leave period do not count as leave availed, a practitioner clarification the older Factories Act carried and the Code preserves.

Days lost to lay-off, days availed as maternity leave, and days availed as annual leave count toward the 180-day threshold for the qualifying check; no fresh leave is earned during those days. The mid-year joiner threshold runs at one-fourth of the days remaining in the calendar year from the date of joining, down from two-thirds under Section 79(2) of the older Factories Act. Carry-forward of unavailed leave is capped at 30 days; any excess over 30 days is encashed by the employer at the close of the calendar year, and the carry-forward cap is itself uncapped under Section 32(1)(vii)(b) where the employer has refused a leave application. Section 32(1)(viii) carries a further worker-friendly enhancement that did not exist under the Factories Act, 1948: a worker may demand encashment of unavailed leave at the close of any calendar year, even within the carry-forward limit, and the employer is required to pay.

Two worked examples sit on the leave file.

A full-year worker who joined on 1 January 2027 and worked 280 days in the calendar year clears the 180-day threshold and earns 280 ÷ 20 = 14 days of leave. Holidays falling inside any availed-leave period during the year are excluded from those 14 days.

A mid-year joiner who came on board on 1 March 2026 has 306 days remaining in the calendar year. The one-fourth threshold for that joiner is 306 ÷ 4 = 77 days. On 200 days worked between 1 March and 31 December 2026, the joiner clears the threshold and earns 200 ÷ 20 = 10 days of leave for the year.

The most common error on leave compliance is carrying over the older Factories Act's two-thirds rule for mid-year joiners. A joiner on 1 March 2026 who would have failed the older two-thirds threshold (306 × 2/3 = 204 days, against 200 worked) clears the OSH Code's one-fourth threshold by a wide margin and earns the 10 days. An HR system that is still configured on the two-thirds rule under-grants leave to mid-year joiners; reconfigure the leave engine to the one-fourth threshold and back-test the FY 2025-26 entries against the new rule.

A second common error is the holiday-absorption mistake. A worker on 10 working days of leave that span Diwali sometimes finds the Diwali holiday counted by HR as one of the 10 availed leave days. Section 32 of the OSH Code expressly excludes holidays falling within a leave period from availed-leave count. Configure the leave engine to exclude paid holidays falling inside a leave window.

Section 43 of the OSH Code resolves a question that ran across the older Acts unevenly: women may be employed in every establishment and in every work type, including in shifts before 6 AM and after 7 PM, subject to additional conditions the appropriate Government has notified. The 6 AM and 7 PM markers are the trigger for the additional conditions, not a prohibition on women's employment outside those hours. The Code's clear position resolves a state-by-state patchwork that constrained women's night-shift employment in factories under the older Factories Act and in shops under the various State Shops and Establishments Acts.

Section 43 itself lists four broad categories of conditions plus a catch-all (consent of the woman worker, safety, holidays, working hours, and "any other condition as may be prescribed"); the granular six-item checklist below runs against Section 43 read with the OSH (Central) Rules and the corresponding State Rules, where the consent, transport, lighting, security, rest, and notified-safety-measures items are spelt out in operational detail.

For the Pune manufacturer's fourteen women workers joining the 2 PM to 11 PM second-line cadence on Monday 15 June, all six items sat on the file by Thursday 11 June: written consent on the prescribed format from each of the fourteen, signed and witnessed; a contracted transport arrangement with two minivans operating between the establishment and three drop-point clusters across Pimpri-Chinchwad, Bhosari, and Nigdi; a lighting audit covering the press shop, the canteen, the locker rooms, the parking area, and the road from the gate to the highway, with the audit report on the file; security staffing of two female guards across the evening shift, plus a male guard at the gate; expanded rest facilities in the women's locker room area; and the Maharashtra Department of Industries, Energy and Labour's notified safety measures, on file in English and Marathi.

Section 44 of the OSH Code separately requires adequate safeguards before a woman is employed in dangerous operations, with the rule-making hook for any restrictions on pregnant women in such operations sitting in Section 82. Section 82 lets the appropriate Government, by rules, prohibit or restrict the employment of pregnant women in factory operations exposing employees to serious risk of bodily injury, poisoning, or disease. The operative restriction lives in the rules, not in the Code text itself; the Pune manufacturer's pre-employment medical-examination protocol for women workers in the press shop runs against the Maharashtra Factories Rules' notified hazardous-process list, with the empanelled occupational-health centre clearing each woman before the shift assignment.

Sections 45 to 58 of the OSH Code consolidate the contract-labour framework that ran under the older Contract Labour (Regulation and Abolition) Act, 1970. Under Section 45(1), the Part applies to every establishment in which 50 or more contract workers are employed, or were employed on any day in the preceding 12 months, through a contractor. Manpower-supply contractors who have employed 50 or more contract workers on any such day are also caught by the same applicability. Raised from 20 under the 1970 Act, the threshold takes smaller engagements out of the licensing regime.

A contractor is the direct employer of the contract worker. Wages, immediate workplace welfare, the licence under Section 47, and the wage register and PF and ESI deposit obligation against the contract workforce all sit on the contractor's books. Five years is the licence validity under Section 48(3) read with the OSH Central Rules, with a single licence from the central licensing authority available for multi-state or all-India deployment under the first proviso to Section 47(3), in place of separate state-by-state licences under the older Act. The second proviso to Section 47(3) requires the central authority to consult the concerned State authorities before issuing such an all-India licence.

The principal employer's chain of liability runs across three sections. Welfare provision sits in Section 53: the principal employer provides the overarching welfare facilities under Sections 23 and 24 where the contractor fails to do so, and the contract worker's access to drinking water, toilets, the canteen at the 100-worker threshold, the crèche at the 50-worker threshold, and the rest rooms at the 50-worker threshold (in factories and mines) all attach at the principal employer's gate where the contractor's provision falls short. Wage default sits in Section 55(3): the principal employer is liable for the wages of the contract worker where the contractor defaults in payment, with recovery from the contractor pursued separately. Engaging an unlicensed contractor is itself an offence under Section 54, irrespective of any reliance on contractor representations.

An arms-length engagement is not a defence under the Code. The Pune manufacturer's contract-labour audit runs four times a year on every contractor on the establishment's roster: current licence number and validity verified against the central licensing authority's database; scope of the licence (state or multi-state) checked against the deployment location; contractor's wage register for the establishment site read against the operator wage rate and the wage period; contractor's PF and ESI deposits verified against the latest monthly EPFO and ESIC challans; and welfare provision verified by walk-through against the contractor's contractual undertakings. The audit memo sits in the contractor file, with the next-quarter review date booked. Where a contractor falls short, the corrective action runs against a 14-day clock; where the contractor fails twice in a 12-month period, the engagement is reviewed for renewal.

Sections 59 to 65 of the OSH Code apply to every establishment in which 10 or more inter-state migrant workers are employed, or were employed on any day in the preceding 12 months. The threshold has been raised from 5 under the older Inter-State Migrant Workmen Act, 1979, narrowing the statutory coverage at the lower end and pulling smaller engagements out of the Part's direct applicability. The Code's definition of inter-state migrant worker has, however, been broadened on a different axis to include a self-migrating worker who has come to the State of employment on her own initiative, in addition to workers engaged through a contractor in a different State, the older 1979 Act's narrower scope. The two changes pull in opposite directions: the threshold raise narrows coverage among small engagements, while the self-migrant inclusion widens coverage among workers who would have fallen outside the 1979 Act regardless of headcount. A practitioner caveat: the OSH Code's definition of inter-state migrant worker under Section 2(1)(zf)(ii) carries a ₹18,000 per month wage ceiling, subject to upward notification by the Central Government. Workers earning above ₹18,000 a month, even where they have crossed State lines for employment, fall outside the Code's ISMW definition and the Section 59 to 65 framework does not attach to them.

Section 60 of the OSH Code, marginally headed "Facilities to inter-State migrant workers", requires the appropriate Government to lay down suitable conditions of work and to ensure that an inter-state migrant worker enjoys parity of access to all benefits available to a local worker of that establishment. The wage-parity rule from Section 13 of the older 1979 Act has been re-located to the Code on Wages, 2019, and runs on every employer through that route rather than through Section 60 of the OSH Code. Accident reporting carries an additional limb under Section 60(ii): where a migrant worker is involved in a fatal accident or serious bodily injury at the workplace, the next of kin is informed and the State of origin's labour department is notified alongside the destination State's authority, in addition to the standard Section 10 notification regime. ESI and EPF coverage runs as it would for any other worker on the principal employer's headcount under the Social Security Code.

Section 61 carries a journey allowance: a lump-sum amount paid by the employer once a year, covering to-and-fro travel between the place of employment and the worker's native place. The amount is fixed by the appropriate Government's rules; the saved older-Act practice carries forward in the interim, with the Maharashtra labour department's notified rate running on the Pune manufacturer's payroll until the final OSH Central Rules notify a fresh figure.

Section 62 carries the public-distribution-system portability rule: the migrant worker may draw rations under the PDS in either the State of origin or the State of employment, on the worker's election. The Building and Other Construction Workers' welfare cess paid under the BOCW Welfare Cess Act, 1996 also follows the worker across States. The portability rule is among the materially new provisions the OSH Code adds; the older 1979 Act did not carry equivalent portability.

For the Pune manufacturer's fifteen incoming workers from West Bengal, the intake checklist runs against the Section 60 to 62 framework: equal operator wages on the appointment letter; PF and ESI registrations opened on day one; a journey allowance budgeted at the Maharashtra-notified rate, paid as a single lump sum at the end of the engagement; and PDS portability documentation prepared for any worker who elects to draw rations in Pune through the engagement period. The accident-reporting protocol carries the West Bengal labour department's contact details on the file alongside the Maharashtra contacts. An intake intimation letter to the West Bengal labour department, against the information-sharing framework Sections 59 to 65 carry across the State of origin and the State of employment, went out the day the contractual engagement was finalised in Howrah.

Section 33 of the OSH Code carries the record-keeping framework. Every establishment maintains the registers prescribed by the appropriate Government, with electronic maintenance permitted as an alternative to physical registers and wage slips issued to every worker on or before payment. Returns are filed in the form, manner, and periodicity the appropriate Government prescribes, electronically or otherwise, under the still-draft Central OSH Rules, 2025 and the applicable State OSH Rules. The retention period for each register sits in the rules; the still-draft Central Rules carry a five-year preservation period from the date of the last entry, mirroring the Wage Code's framework.

All six registers run on the Pune manufacturer's HR system in electronic form, with the audit trail archived monthly, alongside physical printouts for the months an inspector might spot-check. The Inspector-cum-Facilitator's name and address sit on the OSH notice board next to the Wage Code notice board, and the wage slips run electronically through the payroll engine to every employee's registered email and the company's HR portal.

Sections 10, 11, and 12 of the OSH Code carry three separate notification obligations on every employer. A single event at the workplace may trigger one, two, or all three of the notifications, and the forms and timelines run separately across the three. Keep a standing internal reference for the three categories so that the day of an event does not become the day of a compliance breach.

An accident under Section 10 carries a trigger on three legs: a death at the workplace, a bodily injury preventing the worker from working for 48 hours or more immediately following the accident, or any nature of accident the appropriate Government has prescribed by rules. The notification goes to the prescribed authority in the form and within the time prescribed under the still-draft Central Rules and the applicable State rules. Where the accident causes death and occurs in a plantation, in building or other construction work, or in any other establishment that is not a factory or a mine, the prescribed authority is required to complete an inquiry into the cause of death within two months of receiving the notice under Section 10(2). The two-month inquiry rule is triggered by death only, and only in establishments that are not factories or mines.

A dangerous occurrence at the workplace falls under Section 11, whether or not anyone is injured. The trigger is broader than the Section 10 accident trigger: a hose burst, a pressure-vessel rupture, a structural collapse, an electrical short with arc, a chemical leak, or any other event the rules name as a dangerous occurrence falls within Section 11 even where no worker has been injured. The notification goes to the prescribed authority in the form and timeline notified by the appropriate Government.

Notifiable diseases sit in Section 12, with the list of 29 entries running in the Third Schedule of the OSH Code. The diseases run across lead poisoning, silicosis, asbestosis, noise-induced hearing loss, occupational cancer, mercury poisoning, byssinosis, anthrax, toxic nephritis, and twenty other diseases tied to specific working environments. A worker contracting any of those diseases triggers the Section 12 notification, with the form and timeline running on the rules.

The Pune manufacturer's hose-burst event of 5 June fell within Section 11 (no injury, but a dangerous occurrence on the press shop floor), did not fall within Section 10 (no death and no 48-hour bodily injury), and did not fall within Section 12 (no notifiable disease). One notification was due, filed against the Maharashtra Department of Industries, Energy and Labour's prescribed Form by Tuesday 9 June. The internal incident-response protocol, walked through after the event, captured the time of occurrence, the equipment involved, the immediate response, the personnel on the floor, the area cordoned, the corrective action taken, and the preventive measures booked for the next quarterly safety review.

Section 119 of the OSH Code permits a common licence application for an establishment that carries on more than one of the activities the Code regulates: factory operations, beedi-cigar manufacturing, and engagement of contract workers above the 50-worker threshold under Section 45. An employer may apply once for a single combined licence covering any two or all three of those activities, in place of the three separate licences under the three older Acts (Factories Act, 1948; Beedi and Cigar Workers Act, 1966; Contract Labour Act, 1970). The five-year validity for the combined licence is prescribed under the OSH Central Rules read with Sections 47 and 48 of the Code, not by Section 119 itself; Section 119 carries the framework, the validity sits in the licensing rules.

For an establishment running only one of the three activities, the simplification is procedural rather than structural; the single licence still attaches, and the periodic renewal still runs against the five-year clock. For a multi-activity employer, the saving in process and paper is real: one application, one renewal cycle, one common licensing authority, in place of three of each. The Pune manufacturer carries factory operations and a contract-labour engagement above the 50-worker threshold; the company's compliance file holds a combined licence application filed in February 2026 against the still-draft Central Rules' format, with the licence issuance pending the final notification of the rules.

Five mistakes recur in compliance reviews of mid-sized establishments under the OSH Code.

Treating registration as a one-time filing is the first. The Section 3 registration is the entry-level event; the Section 3(4) duty to intimate any change in particulars within 30 days of the change is the recurring duty most establishments forget. A change in the establishment's address, a change in the occupier or owner, a change in the nature of work undertaken, or a crossing into a new headcount band all attract the 30-day intimation clock. Many organisations update their PF, ESIC, and GST registrations against such changes but forget the OSH intimation, and the gap surfaces on inspection or on the next licence renewal.

Misreading the annual health check-up obligation is the second. Section 6(1)(c) of the Code does not require a check-up for every employee in every establishment. The duty attaches to "such age or class of employees, in such establishments or class of establishments, as may be prescribed" by the appropriate Government, and the prescription runs in the rules. Practitioner reading places the typical scope at employees aged 45 and above in factories, mines, plantations, building and construction work, and notified hazardous-process establishments. The error runs in both directions: some employers run blanket programmes (which is over-compliance, not non-compliance, but a budget question worth asking), while others assume the duty is dormant and run nothing. Read the applicable Central or State rules for the prescribed classes and document the policy accordingly.

Carrying over the older Factories Act mid-year leave threshold is the third. Section 79(2) of the older 1948 Act set the mid-year joiner qualifying threshold at two-thirds of the days remaining in the calendar year. Section 32 of the OSH Code reduces it to one-fourth. An HR system still configured on the older two-thirds rule under-grants leave to mid-year joiners, and the gap surfaces on a leave audit or on a worker complaint. Reconfigure the leave engine to the one-fourth threshold and back-test the FY 2025-26 entries against the new rule.

Treating contract labour as an arms-length engagement is the fourth. The principal employer's liability under Sections 53, 54, and 55(3) is structural rather than contractual: where the contractor defaults on wages, the principal employer pays under Section 55(3); where the contractor falls short on welfare, the principal employer steps in under Section 53; engagement of an unlicensed contractor is itself an offence under Section 54. A vendor-management approach that ends with an executed services agreement does not protect the principal employer; an active audit of the contractor's licence, wage register, PF and ESI deposits, and welfare provision sits at the core of OSH Code compliance for any establishment engaging contract labour above the 50-worker threshold.

Filing one notification when three were due is the fifth. Sections 10, 11, and 12 carry three separate notification regimes for accidents, dangerous occurrences, and notifiable diseases respectively, with three separate forms, three separate authorities (where the appropriate Government has prescribed different authorities for the three), and three separate timelines. A single event at the workplace may trigger one, two, or all three. Keep a standing internal reference that maps every plausible event to the applicable notifications, and run the day-of-event checklist against all three before any single filing closes the protocol.

The OSH Code is in force from 21 November 2025 by Gazette Notification S.O. 5321(E). Draft Occupational Safety, Health and Working Conditions (Central) Rules, 2025 were re-published in the Gazette on 30 December 2025 under G.S.R. 934(E); the 45-day public-consultation window closed on 13 February 2026, with the draft taken into consideration on or after 14 February 2026, and final Rules had not been gazetted as of 25 April 2026. State Rules across major States are mixed: Gujarat and Arunachal Pradesh have notified final OSH state rules; Karnataka, Maharashtra, and Kerala have published drafts and remain at draft or partial-notification stage; Delhi and West Bengal have not yet notified final rules across the Code's full chapter set. The MoLE Additional FAQs of 16 March 2026 carry the current authoritative interpretive position, directing employers to apply saved older-Act notifications and the still-draft Central Rules until final Rules notify under the Code itself.

Almost every duty in the OSH Code sits in the live-and-self-executing first layer of the three-layer rollout. Where a duty depends on a form, a retention period, or a prescribed authority, the duty is in force from 21 November 2025 and the prescribed instrument continues to flow from saved older-Act notifications under the Code's saving clauses read with Section 6 of the General Clauses Act, 1897. The substantive duties are not affected by the rule-making delay; the operational forms and timelines are. Labour Code Compliance Calendar threads the OSH Code's event-triggered obligations (the Section 3(4) 30-day intimation clock, the Section 5 commencement notice, the Sections 10 to 12 notification regimes, the Section 32 calendar-year leave register close, the Section 61 annual journey-allowance payment to inter-state migrant workers, and the Section 6(1)(c) annual health check-up for prescribed classes) onto the compliance calendar across the year. Labour Code Implementation Plan closes the series with the recurring failure patterns under all four Codes and a 90-day starter plan a typical mid-sized employer can lift into its own compliance baseline.

The OSH Code governs the workplace itself. The Code on Social Security covers what happens after work hours: provident fund and state insurance running through the working years, gratuity at exit, maternity benefit between, employees' compensation when an injury or death takes the worker out of work, the construction welfare cess, and the new coverage for gig and platform workers who never had a statutory framework before. Code on Social Security 2020 turns to the benefits Code, including the section that has not yet been operatively notified (item 3 of Section 164(1), the EPF Act 1952 repeal entry) and the gig and platform liability that is live in policy and pending in operation.
