Additive Chemical Reaction
This occurs when toxic chemicals add their effects together in producing a biological effect.
Antagonism
This occurs
... [Show More] when the effect of two chemicals is less than expected.
Asphyxiants
These are chemicals that deprive the victim\'s body tissues of oxygen. Examples include carbon monoxide and hydrogen cyanide.
Carcinogens
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)
This lists the general and permanent rules of federal agencies.
Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
This regulates and enforces the cleanup of abandoned hazardous waste sites and hazardous waste sites created prior to RCRA.
Contamination Reduction Corridor (CRC)
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.
Contamination Reduction Zone (CRZ)
This is a warm zone or transition zone. Its purpose is to reduce the probability of contamination in the clean Support Zone.
Contingency plan
This is a written document that sets forth policies and procedures for responding to site emergencies.
Corrosive material
A chemical that causes visible destruction of, or irreversible alterations in, living tissue by chemical action at the site of contact.
Decontamination (Decon)
This is the process of removing or neutralizing contaminants that have accumulated on personnel and equipment.
Ergonomics
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.

Exclusion zone
This is the contaminated area where the cleanup work is to be performed.
Geologic data
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
This 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)
This Standard requires employers to evaluate chemical hazards in their facilities and to communicate the hazard information to employees.
Hazardous waste
This is the term describing a hazardous substance that has no commercial value.
Hot line
This is the outer boundary of the exclusion zone.
Hydrologic data
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)
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
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)
This is the specific amount of a particular material needed to cause a percentage of deaths in a sample group of lab animals.
Lockout
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)
This is a written form containing required information on defined hazardous chemicals and their potential effects.
Mutagens
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.
Oxidizer
This is the term that refers to any material that will gain electrons during a chemical reaction, stimulating the combustion of organic materials.
