BSEE Electrical Safety Alert - Check Those Connections

The Bureau of Safety and Environmental Enforcement (BSEE) has observed a trend of safety issues linked to inadequately maintained electrical connections that compromise wiring integrity. This pattern has given rise to safety incidents, such as fires and arc flashes, underscoring the vital importance of averting these electrical hazards. Poor electrical connections pose a common and significant fire hazard, as they have the potential to generate substantial heat without significantly impeding electric current flow. This renders fuses and circuit breakers ineffective, allowing for escalation of the hazard. It is crucial to address these issues promptly and comprehensively to maintain a safe working environment.

Incident 1: Generator Cable Melting
This incident involved a complete power loss of a temporary generator within the production facility. Upon investigation, the platform electrician identified that the 480-volt alternating current (VAC) #2 phase cable had melted off at the generator bus connection. This was attributed to a loose cable connection at the cable lug. In response to the situation, power was switched over to the platform’s emergency generator. Fortunately, no injuries or damage beyond the wiring were reported. The root cause of the incident was traced back to the faulty cable connection at the cable lug, leading to excessive heat generation and subsequent cable melting.
