What safety measure is crucial for a new burner installation?

A kill switch by each exit is a vital safety measure for a new burner installation. This switch provides an immediate means to shut down the burner in case of an emergency, allowing personnel to quickly react without having to navigate complex controls or procedures. This accessibility can significantly enhance safety for personnel working around the burner and can help prevent accidents from escalating.

While other options may contribute to overall safety, they do not provide the same immediate response capability as strategically placed kill switches. A dual burner system could offer redundancy and improve efficiency, an automatic blow-off valve could help with system pressure control, and a high-pressure cutoff device is important for monitoring and protecting against dangerous conditions. However, the presence of a kill switch ensures that operators have a direct and swift way to disengage the burner during critical situations, which is essential for maintaining a safe working environment.
