U.S. Fire Administration

Dry chemical fire suppression systems are installed in a variety of environments to protect Class B and C hazards. They must be checked periodically to enhance their reliability.

Today’s training vignette, “Inspecting Dry Chemical Fire Suppression Systems” provides an easy-to-use inspection checklist.

Training provides an overview of fire protection topics and does not include all details, requirements or exceptions to the topics that are described. Always refer to nationally recognized design and installation codes and standards, the product manufacturer, or listing details for specific information.

A couple of things I noted

1. the tanks show some corrosion. The corrosion may indicate the need for pressure testing

2. From the picture, I cannot tell if the clearance to the beam meets manufacturers requirements

3. Those tanks are pressurized and the chemical cannot be examined unless the pressure is released. That might be messy.

4. We normally put a tee in the agent piping so we can blow nitrogen through the piping.

5. The agent piping may not be supported properly

But the information lists some good points for a quick visual inspection
