corrosive material - a material that can attack (corrode) metals or causepermanent damage to human tissues such as skin and eyes on contact;COSHH (Control of Substances Hazardous to Health - USA/UK) -COSHH regulations impose a number of obligations on employers; theobjective of the regulations is to promote safe working with potentiallyhazardous chemicals. (South Africa has its own version known as theHazardous Chemical Substances Regulations);cryogenics - materials that exist at extremely low temperatures, such asliquid nitrogen;cutaneous hazard - a chemical that may cause harm to the skin, such asdefatting, irritation, skin rashes or dermatitis;degradation - term generally used to describe the loss of resilience ofmaterial used for protective gloves. Degradation may cause the material tosoften, swell, become hard and brittle, or - in severe cases - disintegrate;density - the weight of a material in a given volume. It is usually given ingrams per millilitre (g/ml);dilution ventilation - dilution of contaminated air with uncontaminated airin a general area, room or building for the purposes of health hazard ornuisance control, and/or for heating and cooling;dose - amount of the agent that has entered the body through the variousroutes of entry;DoT - Common abbreviation for the U.S. Department of Transportation,which regulates the transport of chemicals in the U.S.A.• DOT hazard codes: 1 Explosives; 2.1 Flammable gas; 2.2 Non-flammable gas; 2.3 Poisonous gas; 3 Flammable liquid; 4.1 Flammable solid; 4.2 Spontaneously combustible; 4.3 Dangerous when wet; 5.1 Oxidiser; 5.2 Organic peroxide; 6.1 Poison- keep away from food; 6.2 Infectious material; 7 Radioactive;90
8 Corrosive; 9 Miscellaneous.ED50 (Effective Dose 50) - the amount of material required to produce aspecified effect in 50% of an animal population. (See qualification in thedefinition of LD5O).EINECS - acronym for European Inventory of Existing CommercialChemical Substances.ELINCS - acronym for European List of Notified Chemical Substances;embryotoxins - retard the growth or affect the development of the unbornchild. In serious cases they can cause deformities or death. Mercurycompounds and certain heavy metals, aflatoxin, formamide and radiationare known embryotoxins;etiologic agents - microscopic organisms such as bacteria or viruses,which can cause disease;evaporation rate - the rate at which a liquid changes to vapor at normalroom temperature;explosive (flammable) limits - the Lower Explosive Limit (LEL) is thelowest concentration of vapour in air which will burn or explode uponcontact with a source of ignition. The Upper Explosive Limit (UEL) is thehighest concentration of vapour in air which will burn or explode uponcontact with a source of ignition;explosive (flammable) range - the range between the LEL and the UEL;exposure limits - established concentrations which, if not exceeded, willnot generally cause adverse effects to the worker exposed. Exposure limitsdiffer in name and meaning depending on origin. For example: PermissibleExposure Levels (PELs) are legally enforceable exposure limits, set byvarious OSH bodies including OSHA (USA). PELs are not available for allchemicals. Different exposure limits include:• Time-Weighted Average (TWA): The average airborne concentrationof a biological or chemical agent to which a worker may be exposed ina workday or a work week;• Short Term Exposure Level (STEL): The maximum airborneconcentration of a chemical or biological agent to which a worker maybe exposed in any 15 minute period, provided the TWAEV is notexceeded;91
