HAZWOPER TRAINING EXAM
QUESTIONS AND ANSWERS
Contamination Reduction Zone (CRZ) - ANSWER -This is a warm zone or transition
zone. Its purpose is to reduce the probability of contamination in the clean Support
Zone.
Contingency plan - ANSWER -This is a written document that sets forth policies and
procedures for responding to site emergencies.
Corrosive material - ANSWER -A chemical that causes visible destruction of, or
irreversible alterations in, living tissue by chemical action at the site of contact.
Decontamination (Decon) - ANSWER -This is the process of removing or neutralizing
contaminants that have accumulated on personnel and equipment.
Ergonomics - ANSWER -This is the term that refers to arranging the work environment
for an individual\'s body requirements. It involves designing tasks, work stations,
controls, displays, safety devices, tools, and equipment to fit the worker.
Excavation - ANSWER -Means any man-made cut, cavity, trench, or depression in an
earth surface, formed by earth removal.
Exclusion zone - ANSWER -This is the contaminated area where the cleanup work is to
be performed.
Geologic data - ANSWER -Information having to do with the geology of the earth; facts
about the structure of an area that contains rock and minerals; data used to describe
the physical structure of a specific land site.
Hazard - ANSWER -This is any substance, situation, or condition that is capable of
harming human health, property, or the environment. It represents a potential for harm.
Additive Chemical Reaction - ANSWER -This occurs when toxic chemicals add their
effects together in producing a biological effect.
Antagonism - ANSWER -This occurs when the effect of two chemicals is less than
expected.
Asphyxiants - ANSWER -These are chemicals that deprive the victim\'s body tissues of
oxygen. Examples include carbon monoxide and hydrogen cyanide.
Carcinogens - ANSWER -These are known to cause cancer. This is a chronic effect and
symptoms are not immediate. Examples include benzene and asbestos fibers.
, Code of Federal Regulations (CFR) - ANSWER -This lists the general and permanent
rules of federal agencies.
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) -
ANSWER -This regulates and enforces the cleanup of abandoned hazardous waste
sites and hazardous waste sites created prior to RCRA.
Contamination Reduction Corridor (CRC) - ANSWER -This is the passageway between
the Exclusion Zone and the Support Zone used for the decontamination process. OSHA
letters and CPLs call the corridor a zone.
Hazard Communication Standard (HCS) - ANSWER -This Standard requires employers
to evaluate chemical hazards in their facilities and to communicate the hazard
information to employees.
Hazardous waste - ANSWER -This is the term describing a hazardous substance that
has no commercial value.
Hot line - ANSWER -This is the outer boundary of the exclusion zone.
Hydrologic data - ANSWER -Hydrology is the study of the distribution and flow of global
water. Hydrologic data quantifies water cycles and resources, as well as water quality,
conditions, etc.
Immediately Dangerous to Life and Health (IDLH) - ANSWER -This denotes an
atmosphere that poses an immediate threat to life, would cause irreversible adverse
health effect, or would impair one\'s ability to escape from a dangerous atmosphere.
Irritants - ANSWER -A chemical, which is not corrosive, but which causes a reversible
inflammatory effect on living tissue by chemical action at the site of contact.
Lethal dose (Lethal concentration) - ANSWER -This is the specific amount of a
particular material needed to cause a percentage of deaths in a sample group of lab
animals.
Lockout - ANSWER -This is the process of blocking the flow of energy from a power
source to a piece of equipment and keeping it blocked out.
Material Safety Data Sheet (MSDS) - ANSWER -This is a written form containing
required information on defined hazardous chemicals and their potential effects.
Mutagens - ANSWER -These cause alterations in the genes of an exposed person.
Gene damage can be passed on to children if the mutation occurred in either the sperm
or the egg of the parents. Examples include ethylene oxide, benzene, and hydrazine.
