How can you ensure the sprinkler water supply valve remains in the right position?

Locking the sprinkler water supply valve in the open position is a crucial step to ensure the valve remains functional and ready for use in case of an emergency. This action prevents accidental closure or tampering, which could lead to a failure in the sprinkler system during a fire event.

When the valve is locked in the open position, it ensures a constant supply of water to the sprinkler heads, allowing them to operate effectively when needed. This is especially important in maintaining compliance with safety regulations and protecting property and lives.

While tagging the valve, performing regular visual checks, and placing signage can contribute to overall awareness and monitoring of the valve's status, they do not provide the same level of assurance against unintentional closure as locking the valve does. These practices can help in identifying issues and remind personnel of the importance of keeping the valve operational, but they do not physically secure it in the position required for safety.
