*** CAUTION ***
Do not heat, cut or weld tanks, drums or containers
until the proper steps have been taken to insure that such procedures will not cause
flammable or toxic vapours from substance inside. These can cause an explosion even
though the vessel has been “cleaned”.Vent hollow castings or containers before heating,
cutting or welding. They may explode.
