Air Reactivity - answer Materials that can react or ignite if they are exposed to air.
Auto-refrigeration - answer A phenomenon that occurs during the rapid release (boiling) of a
liquefied gas that causes it to temporarily remain in a liquid state through rapid cooling.
RISK: False assumption of product elimination until the product resumes boiling and subsequent
release.
Biological Agents - answer Biological Agents include bacteria, viruses, fungi, other
microorganisms and their associated toxins. Many microbes reproduce rapidly and require
minimal resources for survival; therefore, they are a potential danger in a wide variety of
occupational settings.

agent" is a misnomer, however, because these agents do not actually affect the blood in any
way.
Boiling Point - answer Temperature at which the transition from a liquid to a gas state occurs. At
this temperature, the vapor pressure of a liquid equals the surrounding atmospheric pressure so
that the liquid rapidly becomes a vapor.
Catalyst - answer a substance that accelerates the rate of a chemical reaction without itself
changing.
Chemical Change - answer Changes that take place on the molecular level. A chemical change
produces a new substance.
Chemical Interactions - answer Caused when two or more chemicals, or the chemical and its

to the amount of water present.
