Lockout: What does lockout prevent?

Explanation:
Lockout is a safety measure that prevents the actuation of a hazard-control system, specifically stopping the discharge of the extinguishing agent. In a CO2 fire suppression system, applying a lockout ensures CO2 cannot be released even if the system is activated or a detector trips, which is essential during maintenance or testing to protect personnel in the area from an accidental discharge. It’s not about triggering test modes, adjusting fan speed, or blocking alert signals—those functions are handled by other controls. The purpose of lockout is to physically prevent the release of CO2, keeping the space safe during service.
