FEMA IS-0005.A | AN INTRODUCTION
TO HAZARDOUS MATERIALS |
QUESTIONS AND CORRECT
ANSWERS | RATED A+ | 2025/2026
GUIDE
Runoff - Correct Answer - Water from rain, snow melt, or irrigation that
flows over the ground surface and returns to streams.
SARA - Correct Answer - Superfund Amendments and Reauthorization
Act of 1986.
SERC - Correct Answer - State Emergency Response Commission.
Solubility in Water - Correct Answer - An indicator of the amount of a
chemical that can be dissolved in water, shown as a percentage or as a
description. A low percent of solubility (or a description of "slight"
solubility or "low" solubility) means that only a small amount will dissolve
in water. Knowing this may help firefighters or personnel cleaning a spill.
Specific Gravity - Correct Answer - A comparison of the weight of the
chemical to the weight of an equal volume of water. Chemicals with a
specific gravity of less than 1 are lighter than water, while a specific
gravity of more than 1 means the chemical is heavier than water. Most
flammable liquids are lighter than water.
, Synergistic Effect - Correct Answer - A biological response to exposure
to multiple chemicals which is greater than the sum of the effects of the
individual agents.
Systemic Toxicants - Correct Answer - Chemical compounds that affect
entire organ systems, often operating far from the original site of entry.
Teratogen - Correct Answer - A material that produces a physical defect
in a developing embryo.
Threshold - Correct Answer - The lowest dose of a chemical at which a
specific measurable effect is observed. Below this dose, the effect is not
observed.
Title III - Correct Answer - The third part of SARA, also known as the
Emergency Planning and Community Right-to-Know Act of 1986.
TLV - Correct Answer - Threshold Limit Values, which are the calculated
airborne concentrations of a substance to which all workers could be
repeatedly exposed 8 hours a day without adverse effects.
TECP Suit - Correct Answer - Totally encapsulating chemical protective
suit. Special protective suits made of material that prevents toxic or
corrosive substances or vapors from coming in contact with the body.
Gas and vapor tight suit.
Toxicity - Correct Answer - The degree of danger posed by a substance
to animal or plant life.
