General Information 100-00-42 100-00-42 DESCRIPTION AND OPERATION Dusts Powder, dusts or clouds may be irritant, harmful or toxic. Avoid breathing dusts from powdery chemical materials or those arising from dry abrasion operations. Wear respiratory protection if ventilation is inadequate. Fine dusts of combustible material can present an explosion hazard. Avoid explosive limits and sources of ignition. Electric Shock Electric shock can result from the use of faulty electrical equipment or from the misuse of equipment in good condition. Make sure that electrical equipment is maintained in good condition and frequently tested. Faulty equipment should be labeled and preferably removed from the workstation. Make sure that flexes, cables, plugs and sockets are not frayed, kinked, cut, cracked or otherwise damaged. Make sure that electrical equipment and flexes do not come into contact with water. Make sure that electrical equipment is protected by the correct rated fuse. Never misuse electrical equipment and never use equipment that is in any way faulty. The results could be fatal. Make sure that the cables of mobile electrical equipment cannot get trapped and damaged, such as in a vehicle hoist. Make sure that the designated electrical workers are trained in basic First Aid. In cases of electrocution: œ switch off the power supply before approaching the victim. œ if this is not possible push or drag the victim from the source of electricity using dry non-conductive material. œ commence resuscitation if trained to do so. œ SUMMON MEDICAL ASSISTANCE. Engine Oils See Lubricants and Grease. Exhaust Fumes These contain asphyxiating, harmful and toxic chemicals and particles such as carbon oxides, nitrogen oxides, aldehydes, lead and aromatic hydrocarbons. Engines should be run only under conditions of adequate exhaust extraction or general ventilation and not in confined spaces. Gasoline (petrol) engine There may not be adequate warning of odor or of irritation before toxic or harmful effects arise. These may be immediate or delayed. Diesel engine Soot, discomfort and irritation usually give adequate warning of hazardous fume concentrations. Fibre Insulation See also Dusts. Used in noise and sound insulation. The fibrous nature of surfaces and cut edges can cause skin irritation. This is usually a physical and not a chemical effect. Precautions should be taken to avoid excessive skin contact through careful organization of work practices and the use of gloves. Fire See also Welding, Foams, Legal Aspects. Many of the materials found on or associated with the repair of vehicles are highly flammable. Some give off toxic or harmful fumes if burnt. Observe strict fire safety when storing and handling flammable materials or solvents, particularly near electrical equipment or welding processes. Make sure, before using electrical or welding equipment, that there is no fire hazard present. Have a suitable fire extinguisher available when using welding or heating equipment.
