Air Conditioning Never disconnect air conditioning lines Contact with Freon will cause burns to your skin and permanent eye damage Burning Freon gas creates Phosgene gas which causes permanent respiratory damage.
Fuel Vapors & Fires • Anytime the fuel system is disconnected (fuel tank, carburetor, fuel pump, fuel injectors etc.),fuel vaporsare present. Prevent fires by… • disconnecting the negative battery terminal • keep sparks away from the fuel vapors • watch those working around you • have a fire extinguisher nearby
Gasoline Safety Do not use gasoline as a solvent. Use a solvent/varsol as a cleaning agent (still flammable). Only store gasoline in approved containers and in small quantities.
