Precauções de saúde e segurança

General Information 100-00-49 100-00-49 DESCRIPTION AND OPERATION The flame is bright, and eye protection should be used, but the ultra-violet emission is much less than that from arc welding, and lighter filters may be used. The process itself produces few toxic fumes, but such fumes and gases may be produced from coatings on the work, particularly during cutting away of damaged body parts, and inhalation of the fumes should be avoided. In brazing, toxic fumes may be produced from the metals in the brazing rod, and a severe hazard may arise if brazing rods containing cadmium are used. In this event particular care must be taken to avoid inhalation of fumes and expert advice may be required. SPECIAL PRECAUTIONS MUST BE TAKEN BEFORE ANY WELDING OR CUTTING TAKES PLACE ON VESSELS, WHICH HAVE CONTAINED COMBUSTIBLE MATERIALS, FOR EXAMPLE BOILING OR STEAMING OUT OF FUEL TANKS. Warning Symbols on Vehicles Decals showing warning symbols will be found on various vehicle components. These decals must not be removed. The warnings are for the attention of owners/operators and persons carrying out service or repair operations on the vehicle. The most commonly found decals are reproduced below together with an explanation of the warnings. TIM101001 1. Components or assemblies displaying the caution triangle and open book symbol advise consultation of the relevant section of the owner literature before touching or attempting adjustments of any kind. TIM01002 2. Components or assemblies displaying the warning triangle with the `electrified' arrow and open book symbol give warning of inherent high voltages. Never touch these with the engine running or the ignition switched on. See Electric Shock in this subsection. TIM0101003 3. Vehicles and replacement components which contain asbestos are identified by this symbol. See Asbestos in this subsection. TIM0101004 4. Components or assemblies displaying this symbol give warning that the component contains a corrosive substance. See Acids and Alkalis in this subsection.
