QUESTIONS AND SOLUTIONS 100 PERCENT
CORRECT
◉ Define: Hazard Materials. Answer: Any material of substance that
poses an unreasonable risk to safety, health and property.
◉ Define: Boiling Point. Answer: The temperature at which a liquid
has a vapor pressure that is equal to atmospheric pressure. Varies
widely.
◉ Define: Flash Point. Answer: The minimum temperature at which
a material will give off ignitable vapors.
◉ Define: Vapor Density. Answer: The weight of a volume of pure
vapor or gas compared to the weight of an equal volume of dry air.

solid or liquid material to the density of water at a specific
temperature.
, ◉ Define: Chronic Exposure. Answer: Usually refers to an exposure
that lasts over a long period of time in small constant doses.
◉ Define: Acute Exposure. Answer: Refers toa short lived and
usually high dosage exposure.
