QUESTIONS & ANSWERS 100%
CORRECT
Additive Chemical Reaction - ANSWERThis occurs when toxic chemicals add their
effects together in producing a biological effect.
Antagonism - ANSWERThis occurs when the effect of two chemicals is less than
expected.
Asphyxiants - ANSWERThese are chemicals that deprive the victim\'s body tissues
of oxygen. Examples include carbon monoxide and hydrogen cyanide.
Contamination Reduction Corridor (CRC) - ANSWERThis 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.
Contamination Reduction Zone (CRZ) - ANSWERThis is a warm zone or transition
zone. Its purpose is to reduce the probability of contamination in the clean Support
Zone.
Contingency plan - ANSWERThis is a written document that sets forth policies and
procedures for responding to site emergencies.
Excavation - ANSWERMeans any man-made cut, cavity, trench, or depression in an
earth surface, formed by earth removal.
Exclusion zone - ANSWERThis is the contaminated area where the cleanup work is
to be performed.
Carcinogens - ANSWERThese 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) - ANSWERThis lists the general and permanent
rules of federal agencies.
Comprehensive Environmental Response, Compensation, and Liability Act
(CERCLA) - ANSWERThis regulates and enforces the cleanup of abandoned
hazardous waste sites and hazardous waste sites created prior to RCRA.
Geologic data - ANSWERInformation 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 - ANSWERThis is any substance, situation, or condition that is capable of
harming human health, property, or the environment. It represents a potential for
harm.
Hazard Communication Standard (HCS) - ANSWERThis Standard requires
employers to evaluate chemical hazards in their facilities and to communicate the
hazard information to employees.
Hazardous waste - ANSWERThis is the term describing a hazardous substance that
has no commercial value.
Hot line - ANSWERThis is the outer boundary of the exclusion zone.
Hydrologic data - ANSWERHydrology 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.
Corrosive material - ANSWERA chemical that causes visible destruction of, or
irreversible alterations in, living tissue by chemical action at the site of contact.
Decontamination (Decon) - ANSWERThis is the process of removing or neutralizing
contaminants that have accumulated on personnel and equipment.
Ergonomics - ANSWERThis 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.
Immediately Dangerous to Life and Health (IDLH) - ANSWERThis 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.
Mutagens - ANSWERThese 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.
Oxidizer - ANSWERThis is the term that refers to any material that will gain electrons
during a chemical reaction, stimulating the combustion of organic materials.
Pathogens - ANSWERThese are biological organisms capable of infecting or
transmitting diseases to humans.
Permissible Exposure Limits (PEL) - ANSWERThis is an enforceable standard of
exposure promulgated by OSHA.
Potentiation - ANSWERThis occurs when a chemical with no known toxic effects
acts together with a known toxic substance to make the toxic substance even more
potent.
