Biodegradable (BOD) - chemical substances which can be converted to materials harmless to the atmosphere by micro-organisms.

Boiling Point - temperature at which a liquid is converted to vapor or gas.

Cancer Assessment Group - a unit of the EPA which assesses regulation of cancer causing substances.

Carbon Recovery Unit (Sniffer) - carbon bed which absorbs perc, regenerates by purging and bed is reused repeatedly.

CAS Registry Numbers - number assigned to individual chemicals to provide access to computerized information from the National Library of Medicine, Washington, D.C.

Chlorinated Hydrocarbon Solvent (perc, III-Trichloroethane) - hydrocarbon solvent to which chlorine has been attached. Will not burn and is low boiling and volatile.

Closed Loop Machines - do not vent to atmosphere. Heat pumps to heat and condense solvent in drying.

Draeqer Pump - hand held bellows pump that draws air through detector tubes to determine concentration of solvent vapors in air.

Explosion Proof Atmosphere - motors and all electrical outlets, switches, etc. are specially wired to eliminate igniting the petroleum solvent in the cleaning system.

Environmental Protection Agency - (EPA) A U.S. Government Agency charged with eliminating pollution of air, water and land.

Flash Point - the temperature at which a substance will ignite when an open flame is passed over it.

Fluorocarbon Solvent - hydrocarbon solvent to which chlorine and Fluorine has been attached. Will not burn and is very low boiling and very volatile.

Hazardous chemical - any chemical which is either a physical or health hazard or both.

Hydrocarbon Solvent (Stoddard) - a solvent derived from petroleum. Hydrocarbon solvents will burn with flash points of l05~l40 degrees F. They have high boiling points and require vacuum for distillation.

Laboratory Test Mice B6C3FI - strain of mice used in studies to determine carcinogenic potential of substances.

Lethal Dose (LD) the concentration of a substance required to kill the lab animal used for the test with a specific material.

Leak Detector - instrument which can detect very low levels of chlorinated or fluorinated solvents. Used in refrigeration industry also.

Material Safety Data Sheets - (MSDS) lists physical and chemical properties of compounds relative to safety requirements, health hazards and first aid recommendations.

Occupational Safety and Health Administration - (OSHA) governmental body concerned with workers exposure to hazardous materials in the United States.

Ozone Layer - a layer of ozone in the stratosphere (10-30 miles from earth) which filters out ultraviolet rays from the sun which are harmful to humans. Rays that cause skin cancer.

Ozone Hole - a hole in the ozone layer that has recently been detected which allows the harmful rays to come through to earth. Hole has been attributed to reaction with chlorinated solvents.

Parts per million (PPM) - unit of measurement for concentration of gas or vapor in air - 1 ppm = .0001%.

Parts per billion (PPB) - unit of measurement for concentration of gas or vapor in air - 1 ppb = .0000001%.

Petro misers - petroleum solvent dryers which reclaim petroleum solvent.

Refrigeration Drycleaning Units - utilize refrigeration to condense and recover solvent. Do not vent to the atmosphere.

Residence time - time required for a solvent to reach the ozone layer from earth.

Science Advisory Board - (SAB) a Board of independent scientists who advise the EPA regarding the carcinogenicity of chemicals.

Solvent Mileage - lbs. of garments cleaned per gallon or drum of solvent.

Super Fund - legislation and funds appropriated by the U.S. Congress for the purpose of cleaning up hazardous waste.

Time Weighted Average (TWA) - an average of the airborne concentration of a material to which a person can be exposed to over an 8 hour workday. Occupational Safety and Health Administration- (OSHA) governmental body concerned with workers exposure to hazardous materials in the United States.
