What safety feature is mandatory on new fuel transfer pumps as per safety standards?

The mandatory safety feature on new fuel transfer pumps, as per safety standards, is the emergency stop button. This feature is critical because it allows for the immediate cessation of pump operation in case of an emergency or hazardous situation, reducing the risk of spills, fires, or accidents. The emergency stop button can be quickly activated by personnel, providing a crucial layer of safety for both operators and the surrounding environment.

While other features, such as an automatic shutoff mechanism or a pressure gauge indicator, may enhance operational safety and efficiency, the emergency stop button is specifically mandated to ensure prompt action can be taken when needed, making it an essential component of fuel transfer pump safety protocols.
