◉ class 2.3
Answer: What is the UN/DOT hazard class for the choking agent
phosgene?
◉ in air of 200 parts per million by volume or less of gas or vapor.
Answer: A chemical is highly toxic if it has a median lethal
concentration (LC50). (Parts per million)
◉ 1. What is the size of the breach of the hazardous material's
container?
2. What form is the hazardous material in?
3. What type of hazardous material involved?
Answer: When planning a response objective, you must know
something about the hazardous material involved. what are three
questions you should ask yourself when determining the response
objectives?
◉ 1. Thermal injury
2. Chemical injury
3. asphyxiation
4. mechanical injury
,Answer: What are four types of harm that can result from
exposure to gases stored in containers that may be under
pressure during a rescue operation?
◉ 1. Department of Transportation (DOT)
2. Environmental Protection Agency (EPA)
3. Occupational Safety and Health Administration (OSHA)
Answer: Identify the organizations whose training requirements
you need to meet to become certified as an Operations-level
responder.

to the public, and packaged in glass or concrete.
Answer: What radioactive materials are Industrial packages
designed to transport?
◉ Low radioactivity such as natural uranium and rubble from
nuclear reactors and packaged in steel, wood or fiberboard.
Answer: Strong, tight packages are designed to transport
radioactive materials with:

2. Placards or labels
3. The shipper's identification number
Answer: What Intermodal equipment, including tank containers
have all the markings
, ◉ Class 6, Division 1.
Answer: The Dot system, materials, other than gas, that are either
known to be so toxic to humans as to afford a hazard to health
during transport, or in the absence of adequate data on human
toxicity, are presumed to be toxic to humans would fall under.
◉ Class 1, Division 3
Answer: Explosives that have a fire hazard and either a minor
blast hazard or a minor projection hazard
◉ Class 2, Division 2
Answer: Non- flammable, nonpoisonous compressed gas,
including compressed gas, liquefied gas, cryogenic gas, and
compressed gas in solution.
◉ Class 4, Division 2
Answer: Material that when in contact with the air and without an
energy supply is liable to self-heat.
◉ Class 5, Division 1
Answer: Material that may, by yielding oxygen, cause the
combustion of other materials.
