LEV3701 PRACTICE QUESTIONS AND
ACCURATE ANSWERS GRADED A+
●● Acid
Answer: A material with a pH value less than 7.
●● Acute health affects
Answer: A health problem caused by relatively short exposure periods to
a harmful substance that produces observable conditions such as eye
irritation, coughing, dizziness, and skin burns.
●● Alpha Particle
Answer: A positively charged particle emitted by certain radioactive
materials, identical to the nucleus of a helium atom. (NFPA 801) Can be
stopped by fabric
●● NFPA 801
Answer: Standard for Fire Protection for Facilities Handling Radioactive
Materials.
●● Asphyxiant
Answer: A materials that causes the victim to suffocate.
,●● Base
Answer: A material with a pH value greater than 7
●● Beta Particle
Answer: An elementary particle, emitted from a nucleus during
radioactive decay, with a signle electrical charge and a mass equal to
1/1837 that of a proton (NFPA 801). Can be stopped by fabric & door.
●● Blister Agent
Answer: A chemical that causes the skin to blister.
●● Blood agent
Answer: A chemical that, when absorbed by the body, interferes with the
transfer of oxygen from the blood to the cells.
●● Boiling point
Answer: The temperature at which a liquid eventually turns to a gas.
●● Carcinogen
Answer: A cancer-causing substance
●● Chemical change
,Answer: The ability of a chemical to undergo an alteration in its
chemical makeup, usually accompanied by a release of some fort of
energy.
●● Chlorine
Answer: A yellowish gas that is about 2.5 heavier than air and slightly
water-soluble. Chlorine has many industrial uses but also damages the
lungs when inhaled; thus, a choking agent.
●● Choking agent
Answer: A chemical designed to inhibit breathing and typically intended
to incapacitate rather than kill.
●● Chronic health hazard
Answer: a health problem occurring after a long-term exposure of a
substance.
●● Contamination
Answer: The process of transferring a hazardous material from its source
to people, animals, the environment, or equipment, all of which can act
as carriers for the material.
●● Convulsant
, Answer: A chemical capable of causing convulsions or seizures when
absorbed by the body.
●● Corrosivity
Answer: The ability of a material to cause damage (on contact) to skin,
eyes, or other parts on the body.
●● Expansion Ratio
Answer: the ratio of the volume increase that occurs when a liquid
material changes to a gas.
●● Exposure
Answer: The process by which people, animals, the environment, and
equipment are subjected to or come in contact with a hazardous material.
●● Fire Point
Answer: The lowest temperature at which a liquid will ignite and
achieve sustained burning when exposed to an ignition source. (NFPA
704)
●● Flammable Range
Answer: The range of concentrations between the LFL and UFL. (NFPA
68)`
