The paint is flammable and must comply with the no smoking regulations. (1)Single component It may contain some toxic and harmful pigments, desiccants and other solvents, which can only be sprayed in a well ventilated place.

There is usually no toxic lead gas produced during welding.Oxyacetylene flames should not be used because they are very hot and can produce smoke containing lead. Some smoke may be produced when the flame is sprayed on the surface with grease, and inhalation should be avoided.
Extra care must be taken to remove excess solder and to ensure that no fine lead dust will be produced.
