What procedure must be performed when a fire extinguisher cylinder fails a hydrostatic pressure test?

When a fire extinguisher cylinder fails a hydrostatic pressure test, it is critical to ensure that the cylinder is properly managed in compliance with safety regulations. Each of the actions listed plays an essential role in maintaining safety and accountability.

The first important procedure involves marking the cylinder irreparably by stamping "CONDEMNED" on it. This step clearly identifies that the unit is no longer safe to use and helps prevent its accidental reuse, which could lead to dangerous situations in a fire emergency.

Additionally, the owner must be notified that the cylinder may not be reused. This ensures that the owner is aware of the status of the equipment and understands the potential risks associated with a failing cylinder.

Finally, providing notification in writing that the cylinder is condemned serves as an official record of the incident and actions taken. This documentation is critical for maintaining compliance with safety protocols and providing liability protection for all parties involved.

In summary, all these procedures are integral to ensuring the safety of individuals and property when a fire extinguisher cylinder fails a hydrostatic pressure test, reinforcing the importance of adhering to NFPA standards.
