WARNING

To prevent accidental release of extinguishing agents to the environment, do not disconnect and weigh cylinders to accomplish the annual agent quantity verification. Disconnecting cylinders to verify agent quantity damages seals and O-rings. Only liquid level methods should be used to determine agent quantity.

• Pipe hangers.

• Nozzle for obstruction.

• Piping for leaks.

• Riser condition.

2. Ensure:

• Detectors unblocked/uncovered.

• Notification appliances in place.

• Manual stations in place and unobstructed.

• Nozzle covers in place.

• Pressure gauge within operating range.

WARNING

To prevent accidental release of extinguishing agents to the environment, do not disconnect and weigh cylinders to accomplish the annual agent quantity verification. Disconnecting cylinders to verify agent quantity damages seals and O-rings. Only liquid level methods should be used to determine agent quantity.
