The First Schedule to the Occupational Safety, Health and Working Conditions Code, 2020 (the OSH Code) is the "List of Industries involving hazardous processes". It has 40 numbered items, from ferrous metallurgical industries to the use of mercury, arsenic and isocyanates. The Schedule's heading cross-refers to section 2(za), the definition of "hazardous process". If your plant may be on the list, our labour law compliance team can help check what follows.

Item 17, chemical industries, has twelve sub-items: (a) coke oven by-products and coal tar distillation products; (b) industrial gases (nitrogen, oxygen, acetylene, argon, carbon dioxide, hydrogen, sulphur dioxide, nitrous oxide, halogenated hydrocarbon, ozone, or any like gases); (c) industrial carbon; (d) alkalies and acids; (e) chromates and dichromates; (f) lead and its compounds; (g) electrochemicals (metallic sodium, potassium and magnesium, chlorates, perchlorates and peroxides); (h) electrothermal products (artificial abrasive, calcium carbide); (i) nitrogenous compounds (cyanides, cyanamides and other nitrogenous compounds); (j) phosphorus and its compounds; (k) halogens and halogenated compounds (chlorine, fluorine, bromine and iodine); (l) explosives (including industrial explosives and detonators and fuses).

What the listing is for

The heading of the Schedule reads "". That is the definition of "hazardous process" (see our definitions article on hazardous process). The Schedule gives the list of industries involving hazardous processes that the definition refers to. The Code does not restate, in the Schedule, what a hazardous process is; read the definition for that.

Several consequences in the Code attach to hazardous processes. The occupier of a factory carrying on a hazardous process has disclosure and responsibility duties in sections 84 and 85 (see sections 84 and 85). Emergency standards for hazardous processes are under section 87 (see sections 86 to 88). Sections 102 and 103 set the penalty for breaching the hazardous-process duty where an accident follows (see sections 102 and 103). For the old-law comparison, the Factories Act, 1948 also had a schedule of industries with hazardous processes (see our note on hazardous processes under the Factories Act).

Items that are new or unusual to see

Reading the list as enacted, some items stand out for modern industries:

  • Item 33: extraction of oil and raw material from scrap tyres.
  • Item 34: cigarette manufacturing.
  • Item 35: ship breaking.
  • Item 36: hazardous waste and e-waste processing plants.
  • Item 37: semiconductor manufacturing.
  • Item 38: styrene manufacturing, handling and processing.
  • Item 39: nano-particles utilising industry.
  • Item 40: mercury, lead tetra-ethyl, manganese, arsenic, chrome, aliphatic series, beryllium, phosgene and isocyanates.

This article does not say which of these items were or were not in any earlier schedule. Compare the enacted Schedule with the list that applied to you under the old Act if the comparison matters for your transition.

Changing the list

Section 131 lets the Central Government, by notification, "amend any Schedule by way of addition, alteration or omission", with the Schedule deemed amended on the notification (see sections 130 to 133). The list above is the list as enacted. Later amendments, if any, are not in the text used here, so check the current Gazette before relying on it.

How to use the list

  1. Match your activity to an item. Read the item as printed. For example, item 23 is "grinding or glazing of metals", not any fabrication.
  2. Check sub-items. Item 17 has twelve sub-items, each with named products.
  3. Check the definition. Being in a listed industry is the start; the definition in section 2(1)(za) also matters.
  4. Identify the appropriate Government. The forms and time limits sit in the Central Rules, 2026 where the Central Government is the appropriate Government, and in State rules otherwise.
  5. Plan the duties. Disclosure, occupier responsibility, medical examination and emergency standards follow.

Example. A unit that makes printed fabrics and another that makes plywood and laminates both fall in item 30 as printed. A unit that only stitches garments does not appear in any item as printed. A unit that processes e-waste falls in item 36.
