General Information 100-00-47 100-00-47 DESCRIPTION AND OPERATION Two Pack Can also contain harmful and toxic unreacted resins and resin hardening agents. The manufacturers instructions should be followed. See also Resin-based Adhesives and Isocyanate Adhesives and Sealers under Adhesives and Sealers. Spraying should preferably be carried out in exhausted ventilated booths removing vapor and spray mists from the breathing zone. Individuals working in booths should wear appropriate respiratory protection. Those doing small-scale repair work in the open workshop should wear air-fed respirators. Pressurized Equipment See High Pressure Air, Lubrication and Oil Test Equipment. Solder Solders are mixtures of metals such that the melting point of the mixture is below that of the constituent metals (normally lead and tin). Solder application does not normally give rise to toxic lead fumes, provided a gas/air flame is used. Oxy-acetylene flames should not be used, as they are much hotter and will cause lead fumes to be produced. Some fumes may be produced by the application of any flame to surfaces coated with grease, and inhalation of these should be avoided. Removal of excess solder should be undertaken with care, to make sure that fine lead dust is not produced, which can give toxic effects if inhaled. Respiratory protection may be necessary. Solder spillage and filings should be collected and removed promptly to prevent general air contamination by lead. High standards of personal hygiene are necessary in order to avoid ingestion of lead or inhalation of solder dust from clothing. Solvents See also Chemical Materials, Fuels (Kerosene), Fire. For example acetone, white spirit, toluene, xylene, trichloroethane. Used in cleaning and dewaxing materials, paints, plastics, resins and thinners. Some may be highly flammable or flammable. Skin contact will degrease the skin and may result in irritation and dermatitis following repeated or prolonged contact. Some can be absorbed through the skin in toxic or harmful quantities. Splashes in the eye may cause severe irritation and could lead to loss of vision. Brief exposure of high concentrations of vapors or mists will cause eye and throat irritation, drowsiness, dizziness, headaches and, in the worst circumstances, unconsciousness. Repeated or prolonged exposure to excessive but lower concentrations of vapors or mists, for which there might not be adequate warning indications, can cause more serious toxic or harmful effects. Aspiration into the lungs, for example through vomiting, is the most serious consequence of swallowing. Avoid splashes to the skin, eyes and clothing. Wear protective gloves, goggles and clothing if necessary. Make sure there is good ventilation when in use, avoid breathing fumes, vapors and spray mists and keep containers tightly sealed. Do not use in confined spaces. When spraying materials containing solvents, for example paints, adhesive, coatings, use extraction ventilation or personal respiratory protection in the absence of adequate general ventilation. Do not apply heat or flame except under specific and detailed manufacturers instructions. Sound Insulation See Fibre Insulation, Foams. Suspended Loads CAUTION: Never improvise lifting tackle. There is always a danger when loads are lifted or suspended. Never work under an unsupported, suspended or raised load, for example a suspended engine. Always make sure that lifting equipment such as jacks, hoists, axle stands and slings are adequate and suitable for the job, in good condition and regularly maintained.
