Toxic vapour detection systems (e.g. Oxytox) may be required in certain circumstances.
Several solvents in use are not flammable but it is still possible that contact with a naked flame would produce acidic and/or toxic gases and all naked flames or cigarettes are unacceptable. Chlorinated hydrocarbons decompose in heat to produce hydrogen chloride, carbon dioxide, carbon monoxide and, under very strong heat or strong ultra-violet rays, phosgene. Cleaning tanks or containers, which have contained flammable solvents, should only be undertaken away from enclosed or poorly ventilated spaces and away from any ignition sources.
Empty drums should never be cut by welding torch.
Prolonged contact with the skin should be avoided, as powerful solvents will remove the natural greases. It is advisable to wear neoprene gloves when hands are exposed to the liquid. Safety glasses should be used if there is any chance of splashes.
