Issues get rather more severe with brake cleaner, containing tetrachloroethylene. As defined within the video, getting brake cleaner on a rusty half to scrub it after which exposing it to the intensive energies of the welding course of suffices to create phosgene.
Used as a devastating chemical weapon throughout World Conflict I, phosgene doesn’t dissolve or in any other case noticeably cut back in efficiency after it enters the lungs.
