CORRECTLY GRADED A+
Superfund - Answers This Federal act addresses the problem of inactive hazardous waste sites:
Toxic Substances Control Act - Answers This act requires chemical companies to research the
effects of new chemicals and notify the EPA before they are manufactured:
The Local Emergency Planning Committee - Answers Under Title III, the primary responsibility
for developing a local plan for handling accidental releases of acutely toxic substances is the
responsibility of:
*Only accidental releases of a certain quantity* - Answers EPCRA requires industries that store
or use certain quantities of acutely hazardous substances to report them under what conditions?
The local role in reducing public risks from hazardous materials includes: - Answers 1)
Developing an emergency plan for hazardous materials incidents
2) Regulating hazardous materials transportation through local ordinances
3) Regulating safe disposal of hazardous waste
LEPC - Answers If you believe a local manufacturer is not in compliance with Title III, you should:
department of transportation - Answers The Federal agency responsible for regulating
hazardous materials transportation is:
NFPA 704 Labeling System - Answers Indicates health, flammability, and reactivity hazards of
Chemicals (through scale of 0-4)v
There are three possible codes for the bottom quarter of the NFPA symbol, what does OXY
mean? - Answers This means this material is an oxidizer. It can easily release oxygen to create
or worsen a fire or explosion hazard.
There are three possible codes for the bottom quarter of the NFPA symbol, what does the
symbol W mean? - Answers This indicates a material that reacts with water to release a gas that
is either flammable or hazardous to health
There are three possible codes for the bottom quarter of the NFPA symbol, what does the tri-
blade propeller mean? - Answers The material is radioactive
Explosives in Class 1 are divided into six divisions, what is 1.1? - Answers consists of explosives
that have a mass explosion hazard. A mass explosion is one that affects almost the entire load
, instantaneously.
explosives in class 1 are divided into six divisions, what is 1.2? - Answers consists of explosives
that have a projection hazard but not a mass explosion hazard.
Explosives in Class 1 are divided into six divisions, what is 1.3? - Answers consists of explosives
that have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but
not a mass explosion hazard.
Explosives in Class 1 are divided into six divisions, what is 1.4? - Answers consists of explosives
that present a minor explosion hazard.
- The explosive effects are largely confined to the package and no projection of fragments of
appreciable size or range is to be expected.
- An external fire must not cause virtually instantaneous explosion of almost the entire contents
of the package.
Explosives in Class 1 are divided into six divisions, what is 1.5? - Answers consists of very
insensitive explosives.
- This division is comprised of substances that have a mass explosion hazard but are so
insensitive that there is very little probability of initiation or of transition from burning to
detonation under normal conditions of transport.
Explosives in Class 1 are divided into six divisions, what is 1.6? - Answers consists of extremely
insensitive articles, which do not have a mass explosive hazard.
- This division is comprised of articles which contain only extremely insensitive detonating
substances and which demonstrate a negligible probability of accidental initiation or
propagation.
Hazard Class 2, Gases. What is division 2.1? - Answers flammable gases
Hazard Class 2, Gases. What is division 2.2? - Answers Non-flammable compressed gas. *non-
toxic*
Hazard Class 2, Gases. What is division 2.3? - Answers Poisonous gas.
Hazard Class 2, Gases. What is division 2.4? - Answers Corrosive gas (Canadian).
Hazard class 3 includes: - Answers flammable and combustible liquids
