The Mizoram Occupational Safety, Health and Working Conditions Rules, 2026
Rule 85. Compulsory disclosure of information by the occupier
Official text
(1) The occupier of every factory carrying on a ‘hazardous process’ shall arrange to obtain or develop information as Material Safety Data Sheet (MSDS) in respect of every hazardous substance or material handled in the manufacture, transportation and storage in the factory. It shall be accessible upon request to a worker for reference.
(2) Every such Material Safety Data Sheet shall include the following information:-
(a) the identity used on the label;
(b) hazardous ingredients of the substance;
(c) physical and chemical characteristics of the hazardous substance;
(d) the physical hazards of the hazardous substance, including the potential for fire, explosion and reactivity;
(e) the health hazards of the hazardous substance, including signs and symptoms of exposure, and any medical conditions which are generally recognized as being aggravated by exposure to the substance;
(f) the primary route(s) of entry;
(g) the permissible limits of exposure prescribed in the schedule under Section 88 of the Code, and in respect of a chemical not covered by the said schedule, any exposure limit used or recommended by the manufacturer, importer or occupier;
(h) any generally applicable precautions for safe handling and use of the hazardous substance, which are known, including appropriate hygienic practices, protective measures during repairs and maintenance of contaminated equipment, procedures for clean-up of spills and leaks;
(i) any generally applicable control measures, such as appropriate engineering controls, work practices, or use of personal protective equipment;
(j) emergency and first aid procedures;
(k) the date of preparation of the Material Safety Data Sheet, or the last change to it; and
(l) the name, address and telephone number of the manufacturer, importer, occupier or other responsible party preparing or distributing the Material Safety Data Sheet, who can provide additional information on the hazardous substance and appropriate emergency procedures, if necessary.
(3) The occupier while obtaining or developing a Material Safety Data Sheet in respect of a hazardous substance shall ensure that the information recorded accurately reflects the scientific evidence used in making the hazard determination. If he/she becomes newly aware of any significant information regarding the hazards of a substance, or ways to protect against the hazards, this new information shall be added to the Material Safety Data Sheet as soon as practicable.
(4) An example of such Material Safety Data Sheet is given in the Schedule to this Rule.
(5) Labeling.-Every container of a hazardous substance shall be clearly labeled or marked to identify:
a) the contents of the container;
b) the name and address of the manufacturer or importer of the hazardous substances;
c) the physical and health hazards; and
d) the recommended personal protective equipment needed to work safely with the hazardous substance:

1. Disclosure of information to workers.
(1) The occupier of a factory carrying on a ‘hazardous process’ shall supply to all workers the following information in relation to handling of hazardous material or substances in the manufacture, transportation, storage and other processes, namely,-i. Requirements of sections 84, 85 and 89 of the Code; ii. A list of ‘hazardous process’ carried on in the factory; iii. Location and availability of all Material Safety Data Sheets as per Rule iv. Physical and health hazards a rising from the exposure to or handling or substances; v. Measures taken by the occupier to ensure safety and control of physical and health hazards; vi. Measures to be taken by the workers to ensure safe handling, storage and transportation of hazardous substances; vii. Personal Protective Equipment required to be used by workers employed in ‘hazardous process’ or ‘dangerous operations’; viii. Meaning of various labels and markings used on the containers of hazardous substances as provided under Rule; ix. Signs and symptoms likely to be manifested on exposure to hazardous substances and to whom to report; x. Measures to be taken by the workers in case of any spillage or leakage of a hazardous substance; xi. Role of workers vis-à-vis the emergency plan of the factory, in particular the evacuation procedures; xii. Any other information considered necessary by the occupier to ensure safety and health of workers. 2. The information required by sub-rule(1) shall be complied and made known to workers individually through supply of booklets or leaflets and display of cautionary notices at the workplaces. 3.
