The Safety Alert is attached. Per BSEE, the fires resulted from an accumulation of gas caused by improperly installed or disconnected exhaust vent piping on gas starters.
Incident 1: Two workers sustained burns to the hands, arms, and face. BSEE investigators discovered that the engine’s air intake hose was disconnected, which may have allowed gas-enriched air to be drawn into the carburetor causing the backfire.
Incident 2: While attempting to start the gas engine of a pipeline pump, the lead mechanic sprayed ether into the engine’s carburetor. The exhaust vent piping for the starter had not been installed. The combination of the gas-rich atmosphere and ether caused the engine to backfire and ignited the
accumulated gas. The lead mechanic, sustained burns to his face, arms, and hands.
The Alert includes important recommendations for proper venting, mechanical integrity awareness training, maintenance, and the use of gas detectors and a temporary fire watch during engine startup.
