During a fuel spill, what should be done to reduce spark hazard?

De-energizing electrical systems during a fuel spill is critical to reducing the spark hazard. Fuel vapors can ignite easily in the presence of sparks or static electricity, making it essential to eliminate any potential sources of ignition. Electrical systems can generate sparks, especially if there is a short circuit or malfunction. By de-energizing these systems, you minimize the risk of any electrical sparks igniting the flammable vapors released from the spilled fuel.

Maintaining safety during such incidents relies heavily on preventing any actions that could lead to ignition. Ensuring that all electrical equipment is turned off and disconnected reduces the likelihood of creating sparks, thereby enhancing the safety of the response crew and surrounding environment.
