   • Use forced air ventilation such as a fan set outside of the trunk.
   • Plug or cap any fuel system openings in order to reduce fuel vapor formation.
   • Clean up any spilled fuel immediately.
   • Avoid sparks and any source of ignition.
   • Use signs to alert others in the work area that fuel system work is in process.
