In many cases when a critical motor fails, revenue is permanently lost every minute until it can be replaced. Critical motors may be air compressor motors, main conveyor drive motors, or even ventilation fan motors. The sense of urgency is almost palpable.
Failure of a fire pump motor similarly creates a sense of urgency. Sometimes, there’s a heightened vigilance during the replacement period. Other times, the risk of running without it means some processes are just shut down.
