Safety laws in India: Factories Act, OSH Code and fire service rules

In short

This topic covers the statutory framework that makes safety a legal duty in India, not merely good practice: the Occupational Safety, Health and Working Conditions (OSH&WC) Code, 2020 — in force from 21 November 2025, which repealed and subsumed the Factories Act, 1948, the Mines Act, 1952, the Dock Workers Act, the Contract Labour Act and ten other central labour laws — together with chemical, explosive, electrical and environmental safety rules, and the State Fire Prevention and Fire Safety Acts that govern fire NOCs for buildings. A fire and safety engineer is hired largely to keep an establishment legally compliant, so the law is examined in every Industrial Safety / Safety Legislation paper, asked in interviews at L&T, Reliance, Tata Steel, BPCL, IOCL, Adani and every EHS consultancy, and used daily by Safety Officers, Fire Officers and factory occupiers. It is also the core of the Diploma/Advanced Diploma in Industrial Safety and of the statutory Safety Officer qualification. Because the Code is new and each State must notify its own OSH rules (several still rely on transitional provisions carrying forward the old Factories Rules), exam answers should name the Code's provisions and note that State rules and thresholds vary.

Explained

The legal architecture: who makes safety law in India

• Constitution: labour, factories, welfare of labour and electricity are in the Concurrent List (Entries 22–24, 36, 38) — both Parliament and States legislate; fire services and public health are State subjects (State List), which is why there is no central fire Act.
• Fundamental rights/duties in play: Article 21 (right to life, read to include a safe workplace and a healthy environment), Article 39(e), Article 42 (just and humane conditions of work), Article 47.
• Hierarchy: Act/Code (Parliament) → Rules/Regulations (appropriate Government) → Notifications and schedules → Indian Standards and the National Building Code (reference documents, mandatory only when a statute, a State by-law or a contract adopts them).
• Judicial foundations: *M.C. Mehta v. Union of India* (1987) laid down absolute liability for hazardous industry (no exceptions, unlike Rylands v. Fletcher's strict liability); *Vellore Citizens' Welfare Forum* (1996) adopted the precautionary principle and polluter pays; the Bhopal gas disaster (1984) produced the hazardous-process amendments of 1987 and the Environment (Protection) Act.
• Appropriate Government: Central for mines, major ports, railways, oilfields and central PSUs; otherwise the State.

The four Labour Codes and what the OSH&WC Code, 2020 contains

• The four Codes, all in force 21 November 2025: Code on Wages, 2019; Industrial Relations Code, 2020; Code on Social Security, 2020; OSH&WC Code, 2020. Together they replaced 29 central labour laws — including the Factories Act 1948, Minimum Wages Act, Industrial Disputes Act and BOCW Act. A repealed Act may be cited in an answer only as the *former* law.
• Coverage of the OSH Code: every establishment with 10 or more workers; a factory means premises with 20 or more workers where a manufacturing process is carried on (40 or more without power) — the former Factories Act thresholds were 10 with power and 20 without. Hazardous-process undertakings and mines are covered irrespective of the number of workers. Contract labour provisions apply at 50 or more contract workers.
• Registration and licensing: one electronic registration per establishment (no repeat registration under multiple laws), with a common return and a single licence for contractors; registration within 60 days of commencement (verify the figure against the notified rules of the State).
• Key duties of the employer (Chapter III): provide a workplace free from hazards that cause injury or occupational disease; provide and maintain a safe plant and system of work; free annual health examination for prescribed classes of workers; issue an appointment letter to every employee; report accidents and dangerous occurrences; comply with the notified occupational safety and health standards.
• Duties of employees: take reasonable care of self and others, co-operate, use provided PPE and devices, not interfere with or wilfully misuse safety appliances, report unsafe situations. Duties of designers, manufacturers, importers and suppliers of articles and substances for use at work are separately specified.
• Safety committee and safety officers: the appropriate Government may require a Safety Committee with equal representation of employers and workers, and whole-time Safety Officers in factories, mines, docks, building work and plantations above notified sizes (in practice broadly the old scales — e.g. factories with 1,000 or more workers, or hazardous-process factories; the exact numbers are in each State's OSH rules, so quote them as notified, not from memory).
• Institutions: National Occupational Safety and Health Advisory Board (replaces the separate advisory committees), Inspector-cum-Facilitator replacing the Inspector of Factories (a facilitation-first role — advice and web-based random inspection rather than only prosecution), and Occupational Safety and Health Standards notified centrally.
• Hours and leave (the operative welfare numbers): maximum 8 hours a day and a 6-day week; overtime at twice the ordinary wage; spread-over and rest-interval limits; annual leave with wages after 180 days of work (240 days under the former Factories Act), at 1 day for every 20 days worked; no worker to work more than the notified overtime hours in a quarter. Night work by women is permitted with consent and prescribed safety conditions.
• Welfare facilities: drinking water, latrines and urinals, washing and bathing, first-aid boxes, canteen (above a notified strength, commonly 100 workers), crèche, welfare officer, ambulance room/occupational health centre in hazardous establishments, free annual medical examination, and welfare facilities for contract labour charged to the principal employer if the contractor defaults.
• Hazardous process and dangerous operations: the Code continues the former Act's scheme — a list of hazardous processes (petrochemicals, pesticides, dyes, asbestos, fertiliser, rubber, cement, paper, pharmaceuticals, among others), compulsory disclosure of information to workers and to the Inspector-cum-Facilitator, an on-site emergency plan, medical surveillance, permissible limits of exposure to chemical substances, the worker's right to warn of imminent danger, and the right to refuse work where there is reasonable apprehension of death or serious injury.
• Offences and penalties: graded; the headline exposure for a contravention causing death is imprisonment up to 2 years or a fine up to ₹5,00,000 or both, and the court may direct part of the fine as compensation; a general contravention attracts a fine up to ₹3,00,000; obstructing an Inspector-cum-Facilitator and repeat offences carry enhanced punishment; many offences are compoundable and a first-time minor contravention may attract an improvement notice before prosecution. Penalty values are as in the Code; the precise figure for a given offence should be read from the section.
• What the Code changed in substance: single registration, single licence, single return, electronic filing; thresholds raised; facilitation-first inspection; statutory appointment letters and free health check-ups; national OSH standards instead of 13 separate rulebooks; inter-State migrant worker provisions and a national database.

Former Factories Act, 1948 — the framework still examined

Universities still teach its structure because the OSH Code carried most of it forward and exam questions are framed in its language.

• Scheme: 120 sections, 11 chapters — Chapter III Health (ss.11–20: cleanliness, disposal of wastes, ventilation and temperature, dust and fume, artificial humidification, overcrowding 14.2 m³ per worker, lighting, drinking water, latrines, spittoons), Chapter IV Safety (ss.21–41: fencing of machinery, work on or near machinery in motion, employment of young persons on dangerous machines, striking gear, self-acting machines, casing of new machinery, hoists and lifts, lifting machines, revolving machinery, pressure plant, floors/stairs/means of access, pits and openings, excessive weights, eye protection, dangerous fumes and confined spaces, explosive or inflammable dust and gas, s.38 precautions against fire, safety of building and machinery, s.40B Safety Officers), Chapter IVA hazardous processes (ss.41A–41H, added 1987 after Bhopal), Chapter V Welfare, Chapter VI Working hours, VII young persons, VIII leave with wages.
• Occupier (s.2(n)): the person with ultimate control over the affairs of the factory; in a company, a director; the occupier and manager carry personal criminal liability — a point interviewers probe.
• Landmark numbers that are still asked: overcrowding 14.2 m³/worker (9.9 m³ for pre-1948 factories), cooling drinking water above 250 workers, canteen above 250, crèche above 30 women, ambulance room above 500, welfare officer above 500, safety officer above 1,000, first-aid box 1 per 150 workers. Under the OSH Code these trigger numbers are reset by the notified rules — give the Code's figure where known and name the facility rather than guess the threshold.
• Rights created: right to know, right to be warned, right to refuse unsafe work, right to participate through the safety committee.

Fire safety law: State fire Acts, the NOC and the National Building Code

• There is no central fire Act. Fire services are run by States/UTs; each has its own enactment — for example the Maharashtra Fire Prevention and Life Safety Measures Act, 2006, the Tamil Nadu Fire Service Act, 1985, the Delhi Fire Service Act, 2007, the Kerala Fire Force Act, 2021, and comparable Acts in Karnataka, Gujarat, West Bengal, Telangana and Andhra Pradesh. The Directorate General Fire Services, Civil Defence and Home Guards (MHA) advises and standardises but does not license.
• Typical statutory scheme of a State fire Act: classification of buildings by occupancy and height; a schedule of fire prevention and life safety measures per class; provisional NOC on plans before construction and final NOC before occupancy; periodic (commonly annual or biennial) renewal with a licensed agency's certificate of compliance — in Maharashtra, Form B half-yearly certification by a licensed agency; powers of the Fire Officer to inspect, to serve a notice of deficiency, to seal or disconnect services, and to recover fire-fighting charges; offences and fines; appeal to a designated authority.
• National Building Code of India, 2016 (SP 7, with amendments) — Part 4 Fire and Life Safety is the technical reference: occupancy classification A to J, the letter I being unused (A residential, B educational, C institutional, D assembly, E business, F mercantile, G industrial, H storage, J hazardous), Types 1–4 construction by fire resistance, travel distance and exit-width rules, compartmentation, staircase and refuge-area requirements, and the schedule of fire protection systems by occupancy and height (wet riser, down-comer, yard hydrant, automatic sprinklers, detection and alarm, static water tank, pumps). NBC is a recommendatory code that becomes legally binding when a State fire Act, municipal by-law, development control regulation or contract adopts it — most do.
• Supporting Indian Standards (quote the current edition; several older numbers are withdrawn): IS 3844 for internal hydrants, IS 15105 for sprinkler installations, IS 2190 for portable extinguisher selection and maintenance, IS 2189 for automatic fire detection and alarm systems, IS 15683 for portable extinguishers, IS 1641/1642/1643 for fire safety of buildings.
• Where fire duties sit in other law: OSH Code (means of escape, fire precautions, emergency plan), Petroleum Rules, 2002 and SMPV(U) Rules, 2016 (CCOE/PESO licences for petroleum and compressed-gas storage), Explosives Act, 1884 / Explosives Rules, 2008, Gas Cylinders Rules, 2016, and the Model Building Bye-Laws, 2016 (MoHUA) used by municipal bodies. High-rise, hospital and school fire safety is also enforced through Supreme Court and High Court directions after major fires (Uphaar 1997, AMRI Kolkata 2011, Surat Takshashila 2019).

The allied statutes a safety engineer must know

• Environment (Protection) Act, 1986 and rules framed under it — the umbrella for chemical safety:
  • Manufacture, Storage and Import of Hazardous Chemical (MSIHC) Rules, 1989 — threshold quantities, safety report, on-site and off-site emergency plans, MSDS, notification of major accidents; Chemical Accidents (Emergency Planning, Preparedness and Response) Rules, 1996 — Central, State, District and Local crisis groups.
  • Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 (as amended); Solid Waste Management Rules, 2026, in force 1 April 2026, replacing the 2016 Rules; Bio-Medical Waste Rules, 2016; E-Waste (Management) Rules, 2022; Battery Waste Management Rules, 2022.
  • Public Liability Insurance Act, 1991 — compulsory no-fault insurance for handlers of hazardous substances, plus a contribution to the Environment Relief Fund; relief on a no-fault basis without proving negligence.
  • National Green Tribunal Act, 2010 — specialist tribunal for environmental claims and compensation.
• Factory-adjacent plant statutes: Boilers Act, 2025 (replaced the Boilers Act, 1923) with the Indian Boiler Regulations, 2026 in force from October 2026 superseding IBR 1950 — registration, inspection and certification of boilers, boiler operation engineers and attendants; Static and Mobile Pressure Vessels (Unfired) Rules, 2016; Electricity Act, 2003 with the CEA (Measures relating to Safety and Electric Supply) Regulations, 2023 (which superseded the 2010 Regulations) — electrical safety, authorised persons, earthing, clearances; Atomic energy: the SHANTI Act, 2025 (assent 20 December 2025) repeals the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010, with AERB the regulator — commencement and liability provisions are not yet settled, so do not quote them.
• Compensation and social security: the Code on Social Security, 2020 (in force 21 November 2025) subsumed the Employees' Compensation Act, 1923, ESI Act, 1948, EPF Act, Maternity Benefit Act and Payment of Gratuity Act. Compensation for employment injury and occupational disease: ESI benefit where ESI applies, otherwise employer's liability on the Employees' Compensation formula; notified occupational diseases are presumed to arise out of employment.
• Transport and construction: Motor Vehicles Act, 1988 (as amended 2019) and the Central Motor Vehicles Rules for hazardous-goods transport (TREM card, driver training, placarding); building and other construction work is now within the OSH Code (the BOCW Act, 1996 stands repealed), with the cess now levied under the Code on Social Security, 2020 (the Building and Other Construction Workers' Welfare Cess Act, 1996 stands repealed by that Code).
• Disaster Management Act, 2005 — NDMA/SDMA/DDMA, district disaster plans, and the off-site emergency interface with industry.

Compliance in practice: what the law requires you to produce

1. Registration of the establishment electronically; display of the notice of periods of work, abstracts of the Code and rules, and the name of the Inspector-cum-Facilitator.
2. Appointments in writing: occupier/employer declaration, manager, Safety Officer(s), Welfare Officer, Fire Officer, competent persons for lifting machines, pressure vessels and scaffolds.
3. Statutory registers and records: accident and dangerous-occurrence register, inspection and test certificates for hoists, lifts, lifting machines, pressure plant, examination of hazardous machinery, health records of workers in hazardous processes, PPE issue, overtime and leave registers, muster roll — with the common electronic return.
4. Reporting: accident/dangerous occurrence to the Inspector-cum-Facilitator within the prescribed period; fatal accidents also to police where required; major accident notification under MSIHC; notifiable occupational diseases by the certifying surgeon and employer.
5. Plans and audits: on-site emergency plan with mock drills (commonly rehearsed at least once every six months — follow the notified rule), safety audit (reference the Indian Standard on occupational safety and health audit), HAZOP/QRA for major-hazard installations, and off-site plan input to the District Crisis Group.
6. Fire: provisional and final fire NOC, periodic renewal certificate from a licensed agency, trained fire teams, extinguisher and hydrant testing records, and an occupancy-specific evacuation plan.
7. Inspection readiness: facilitation-first does not remove liability — the occupier and manager remain personally liable, and an improvement or prohibition notice must be complied with within the stated time.

Key points

• OSH&WC Code, 2020 - in force 21 November 2025; consolidates 13 central OSH laws including the former Factories Act, Mines Act, Dock Workers Act, Contract Labour Act and BOCW Act.
• Factory under the Code - 20 or more workers with power, 40 or more without; establishment coverage starts at 10 workers.
• Hazardous process / mine - covered regardless of worker count; no threshold shelter.
• Occupier - the person with ultimate control; in a company, a director — criminal liability is personal, not only corporate.
• Inspector-cum-Facilitator - the Code's inspecting authority, with a web-based randomised inspection scheme and an advisory mandate.
• Employer duties - hazard-free workplace, safe plant and system of work, free annual health examination, appointment letter, accident reporting, compliance with notified OSH standards.

• Penalty for contravention causing death - up to 2 years' imprisonment or fine up to ₹5,00,000 or both, with part of the fine payable as compensation.
• Fire is a State subject - no central fire Act; a State Fire Prevention/Fire Service Act licenses through provisional and final NOCs plus periodic renewal.
• NBC 2016 Part 4 - occupancy groups A to J (the letter I is not used), Types 1-4 construction, travel distance and exit rules, system schedule by height/occupancy; binding only when adopted by a State or by-law.
• MSIHC Rules, 1989 - threshold quantities, safety report, on-site and off-site emergency plans; Chemical Accidents Rules, 1996 create the four crisis groups.
• Public Liability Insurance Act, 1991 - compulsory no-fault insurance for hazardous-substance handlers, with Environment Relief Fund contribution.
• Absolute liability - *M.C. Mehta* (1987): a hazardous enterprise is liable for harm with no exceptions and irrespective of fault.
• Boilers Act, 2025 + IBR 2026 - current boiler law, replacing the 1923 Act and IBR 1950; CEA Safety Regulations, 2023 are the current electrical safety regulations.
• Code on Social Security, 2020 - route for employment-injury compensation (ESI, or the Employees' Compensation formula); notified occupational diseases are presumed occupational.
• PESO/CCOE licences - Explosives Rules 2008, Petroleum Rules 2002, SMPV(U) 2016, Gas Cylinders Rules 2016 for explosives, fuels and compressed gases.
• Disaster Management Act, 2005 - district and State plans, the off-site emergency interface for major-hazard units.

Formulas and examples

Example 1 — Does the OSH Code's factory chapter apply? A unit in Coimbatore runs CNC machines (electric power) with 18 permanent workers and 6 contract workers; a second unit does hand-polishing of stone with 32 workers and no power.

• Unit 1: total workers = 18 + 6 = 24 (contract workers count as workers employed in the premises) ≥ 20 with power → factory provisions apply.
• Unit 2: 32 workers without power, threshold 40 → not a factory, but it has ≥ 10 workers, so the Code applies to it as an establishment (registration, duties, hours, welfare).
• If Unit 2 handled a hazardous process, it would be covered irrespective of the count.

Example 2 — Annual leave and overtime. A worker in a Pune factory worked 212 days in 2026 at an ordinary wage of ₹600 per 8-hour day, and did 18 hours of overtime in the quarter.

• D = 212 ≥ 180 → leave earned. L = floor(212/20) = floor(10.6) = 10 days of annual leave with wages.
• Ordinary hourly rate = 600 / 8 = ₹75/hour. OT rate = 2 × 75 = ₹150/hour.
• OT wages = 18 × 150 = ₹2,700.
• Leave wages payable if encashed at the daily rate = 10 × 600 = ₹6,000.

Example 3 — Overcrowding check. A workroom is 24 m × 12 m with a clear height of 5.0 m, and 180 workers are deployed in it.

• Height counted = min(5.0, 4.2) = 4.2 m. Volume = 24 × 12 × 4.2 = 1,209.6 m³.
• Permissible workers = 1,209.6 / 14.2 = 85.18 → 85 workers.
• 180 deployed against 85 permissible → overcrowded; the excess is 95 workers. Either reduce the number in the room or provide additional floor area of (180 − 85) × 14.2 / 4.2 = 95 × 3.381 = 321.2 m².

Example 4 — Statutory accident statistics for the return. A plant with 450 workers worked 9,60,000 man-hours in a year; there were 6 lost-time injuries, one of them a fatality, and 1,340 man-days lost excluding the fatality (a death is charged at 6,000 man-days).

• Total man-days charged = 1,340 + 6,000 = 7,340.
• FR = 6 × 1,000,000 / 960,000 = 6.25 lost-time injuries per million man-hours.
• SR = 7,340 × 1,000,000 / 960,000 = 7,645.8 man-days lost per million man-hours.
• Incidence rate = 6 × 1,000 / 450 = 13.3 injuries per 1,000 workers.
• The fatality triggers reporting to the Inspector-cum-Facilitator and attracts the Code's death-related penalty exposure if a contravention caused it.

Example 5 — Fire NOC route for a new building. A 42 m high commercial office block in Navi Mumbai (occupancy Group E under NBC 2016).

• Height > 15 m → a high-rise for the State fire Act; plans must get a provisional fire NOC from the Chief Fire Officer before construction.
• NBC 2016 Part 4 schedule for Group E at this height typically requires wet riser, yard hydrants, automatic sprinklers, automatic detection and alarm, static water storage with fire pumps, refuge areas above the notified height, two protected staircases and compartmentation — the exact schedule is read from the Part 4 table for the occupancy and height.
• Final NOC before the occupancy certificate; thereafter periodic renewal with a licensed agency's compliance certificate (half-yearly Form B in Maharashtra).
• A deficiency notice unattended can lead to sealing or disconnection of water and power supply.

Where it is used

• Process and chemical plants (Reliance, IOCL, BPCL, UPL, Deepak Nitrite): MSIHC safety reports, on-site emergency plans, PESO licences, statutory registers and the OSH Code's hazardous-process obligations.
• Manufacturing and steel (Tata Steel, JSW, Maruti, Bosch): Safety Officer and Safety Committee duties, machine guarding, pressure-plant and lifting-machine test certificates, accident reporting.
• Construction and infrastructure (L&T, Afcons, NHAI and metro projects): construction work now under the OSH Code, welfare cess, contractor licensing, height-work and scaffolding competent persons.
• Buildings, malls, hospitals, IT parks, hotels: provisional and final fire NOC, periodic renewal certificates, NBC Part 4 system design — the daily work of a Fire Officer or fire-safety consultant.
• Job roles: Safety Officer / EHS Executive (the statutory post), Fire and Safety Officer, Fire Safety Auditor, licensed fire-system agency engineer, insurance risk surveyor, third-party safety auditor, labour-law compliance analyst.
• Exams and licences: GATE and PSU safety papers, Diploma/Advanced Diploma in Industrial Safety (the common statutory qualification for Safety Officer), state fire service recruitment, NEBOSH/IOSH-aligned corporate roles.

Interview questions

• Q: Which law governs factory safety in India today? A: The Occupational Safety, Health and Working Conditions Code, 2020, in force from 21 November 2025, which repealed and subsumed the Factories Act, 1948 along with 12 other central OSH laws; State OSH rules supply the detail.
• Q: What is the worker threshold for a factory under the OSH Code? A: 20 or more workers where power is used, or 40 or more without power — raised from 10 and 20 under the former Factories Act; hazardous processes are covered at any number.
• Q: Who is the "occupier" and why does it matter? A: The person with ultimate control over the affairs of the establishment — in a company, a nominated director. It matters because statutory liability, including imprisonment, is personal.
• Q: Name three statutory duties of an employer under the OSH Code. A: Provide a workplace free of hazards likely to cause injury or occupational disease, provide a free annual health examination to prescribed classes of workers, and report accidents and dangerous occurrences to the Inspector-cum-Facilitator.
• Q: Does a worker have a legal right to refuse unsafe work? A: Yes — carried forward from the hazardous-process provisions: a worker who has a reasonable apprehension of imminent danger of death or serious injury may warn the employer and refuse, and the employer must investigate and remedy it.
• Q: Which central Act governs fire safety in buildings? A: None — fire services are a State subject, so each State has its own fire prevention/fire service Act; the National Building Code 2016 Part 4 supplies the technical requirements and becomes binding when a State or local by-law adopts it.
• Q: What is the difference between a provisional and a final fire NOC? A: The provisional NOC approves the fire and life-safety design at the plan stage before construction; the final NOC certifies the installed systems before occupancy and precedes the occupancy certificate.
• Q: Strict liability or absolute liability for a hazardous industry in India? A: Absolute liability, laid down in M.C. Mehta v. Union of India (1987) — the enterprise is liable for harm from a hazardous activity without any of the exceptions available under strict liability, and regardless of fault.
• Q: What does the Public Liability Insurance Act, 1991 require? A: Any person handling hazardous substances above notified quantities must take out insurance to provide immediate no-fault relief to accident victims and contribute to the Environment Relief Fund.
• Q: Where do the on-site and off-site emergency plans come from? A: The on-site plan is the occupier's duty under the OSH Code's hazardous-process provisions and the MSIHC Rules, 1989; the off-site plan is prepared by the District/State authority under the MSIHC and Chemical Accidents Rules, with the Disaster Management Act, 2005 machinery.
• Q: Which law covers a boiler explosion in a plant today? A: The Boilers Act, 2025 with the Indian Boiler Regulations, 2026 (in force October 2026) for registration, inspection and operator competence, alongside the OSH Code's pressure-plant and accident-reporting duties, and compensation under the Code on Social Security, 2020.
• Q: An inspection is now "facilitation-first". Does that reduce the occupier's liability? A: No. Inspection style changed to advisory and randomised web-based assignment; the duties, personal criminal liability and penalties — including up to two years' imprisonment or a fine up to ₹5,00,000 where a contravention causes death — remain.

Common mistakes

• Quoting the Factories Act, 1948 as current law. It was repealed on 21 November 2025 by the OSH&WC Code, 2020 and may be named only as the former Act; the same applies to the Mines Act, 1952, the Dock Workers Act, the BOCW Act, 1996 and the Employees' Compensation Act, 1923.
• Using the old thresholds (10 with power / 20 without) or 240 days for leave — the Code's figures are 20/40 and 180 days.
• Assuming there is a central Fire Act or that NBC 2016 is itself law: NBC is a code that becomes binding only when adopted by a State Act, municipal by-law or contract.
• Confusing strict liability with absolute liability, or treating the Public Liability Insurance Act's relief as requiring proof of negligence — it is no-fault.
• Reciting State-specific thresholds (canteen, crèche, Safety Officer scale, drill frequency) as central law. They are in the notified State OSH rules and vary; name the facility and say the threshold is as notified.
• Mixing up the regulators — PESO for explosives and petroleum, Chief Inspector of Boilers for boilers, Electrical Inspector under the CEA Regulations 2023, Inspector-cum-Facilitator for the OSH Code, State Fire Officer for NOCs.
• Writing the injury frequency rate per 100,000 man-hours or per 200,000 man-hours in an Indian statutory answer — the Indian convention is per million man-hours; always state the base.
