Manufacture, Storage and Import Of Hazardous Chemical (Amendment) Rules, 1989
As per the powers conferred by Section 6, 8 and 25 of the Environment (Protection) Act, 1986 (29 of 1966), this regulation was enacted by Ministry of Environment & Forests (MoEF) and later amended in 1994 and 2000. It regulates the manufacture, storage and import of hazardous chemicals in India. These rules are framed under 20 sections, these 20 sections refer to 12 schedules for regulatory requirements to be followed while handling hazardous chemicals
Hazardous chemicals are the chemicals owing to their physical and chemical properties are capable of producing major accident hazards, they are broadly classified as
·
Toxic chemicals
·
Flammable gases
·
Flammable liquids
· Explosives
Accidents mean - an incident involving loss of life inside or outside
the installation, or ten or more injuries inside and/or one or more injuries
outside or release of toxic chemicals or explosion or fire or spillage of
hazardous chemicals resulting in on-site or off-site emergencies or damage to
equipment leading to a stoppage of process or adverse effects on the environment.
There are different criteria /formats /guidelines which are to be followed by all industries dealing with hazardous chemicals for submitting any report during ongoing/new industrial activity. These requirements are provided in 12 schedules
SCHEDULES
Schedule 1: This schedule consists of two parts,
in part 1 there are certain criteria listed to know under which classification
does the hazardous material belong to and in part 2 there are “ 684” hazardous chemicals
listed down . Coming to part 1 the following criteria are used to classify
hazardous materials
CRITERIA
FOR TOXIC CHEMCIALS: This
helps us to understand the toxicity of hazardous materials
Sr No |
Toxicity |
Oral Toxicity (LD 50
mg/kg) |
Dermal Toxicity (LD 50 mg/kg) |
Inhalation Toxicity (LC 50 mg/l) |
1 |
Extremely toxic |
>5 |
<40 |
<0.5 |
2 |
Highly toxic |
>5-50 |
>40-200 |
<0.5-2.0 |
3 |
Toxic |
>50-200 |
>200-1000 |
>2-10 |
CRITERIA FOR FLAMMABLE GASES: Gases which at
20oC and at standard pressure of 101.3KPa are :-
OR
· Extremely flammable liquids: chemicals which have flash point lower than or equal to 23o°C and boiling point less than 35o°C.
SCHEDULE 2 and 3
Schedule
2 and schedule 3 are some hazardous chemicals with assigned threshold
quantities. When a site handles hazardous chemicals more than the thresholds,
the site will be regarded as major accident hazards (MAH) installations (isolated storage and industrial activity at a
site handling (including transport through carrier or pipeline) of hazardous chemicals equal to or in
excess of the threshold quantities and subject to reporting, safety
audit and contingency plan requirements.
SCHEDULE 4
This
schedule lists down the types of industrial processes that are planned to be
installed for the production, processing or treatment of organic or inorganic
chemicals which requires use of hazardous chemicals, some industrial processes
listed are
·
Alkylation
·
Condensation
·
Esterification
·
Halogenations and
manufacture of halogens
·
Hydrogenation
·
Hydrolysis
·
Oxidation
·
Polymerization
·
Sulphonation etc
