A+ Grade
This Federal act addresses the problem of inactive hazardous waste sites:
- correct answer Superfund
This act requires chemical companies to research the effects of new chemicals and notify the EPA before
they are manufactured:
- correct answer Toxic Substances Control Act
Under Title III, the primary responsibility for developing a local plan for handling accidental releases of
acutely toxic substances is the responsibility of:
- correct answer The Local Emergency Planning Committee
EPCRA requires industries that store or use certain quantities of acutely hazardous substances to report
them under what conditions?
- correct answer *Only accidental releases of a certain quantity*
1) Developing an emergency plan for hazardous materials incidents
2) Regulating hazardous materials transportation through local ordinances
3) Regulating safe disposal of hazardous waste
- correct answer The local role in reducing public risks from hazardous materials includes:
If you believe a local manufacturer is not in compliance with Title III, you should:
- correct answer LEPC
The Federal agency responsible for regulating hazardous materials transportation is:
- correct answer department of transportation
, Indicates health, flammability, and reactivity hazards of Chemicals (through scale of 0-4)v
- correct answer NFPA 704 Labeling System
This means this material is an oxidizer. It can easily release oxygen to create or worsen a fire or
explosion hazard.
- correct answer There are three possible codes for the bottom quarter of the NFPA symbol, what does
OXY mean?
This indicates a material that reacts with water to release a gas that is either flammable or hazardous to
health
- correct answer There are three possible codes for the bottom quarter of the NFPA symbol, what does
the symbol W mean?
The material is radioactive
- correct answer There are three possible codes for the bottom quarter of the NFPA symbol, what does
the tri-blade propeller mean?
consists of explosives that have a mass explosion hazard. A mass explosion is one that affects almost the
entire load instantaneously.
- correct answer Explosives in Class 1 are divided into six divisions, what is 1.1?
consists of explosives that have a projection hazard but not a mass explosion hazard.
- correct answer explosives in class 1 are divided into six divisions, what is 1.2?
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.
- correct answer Explosives in Class 1 are divided into six divisions, what is 1.3?
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.
