The enterprise shall identify the existing dust explosion hazard places, determine the explosion hazard of the generated dust, analyze the risk factors of dust explosion, and evaluate and control the risk of dust explosion.

Verifying that a firefighting foam system accurately proportions foam and water is critical to the system’s effectiveness in the event of a fire. If the premix solution is mixed too lean—not enough foam concentrate and too much water—it may not be able to extinguish the fire. If the premix solution is mixed too rich—too much foam concentrate and not enough water— there is a risk running out of foam before the fire is fully extinguished.

When a suppression system is designed for a room, it’s designed to reach a certain concentration and then hold that concentration for a specific amount of time. It’s ability to hold this concentration is crucial for its ability to put out a fire. Most rooms, especially server rooms and electrical rooms, have a lot of wiring, conduit, HVAC ducts, and other components coming into the room. All of these penetrations of the walls act as potential areas where the gas can leak out and cause the room to not adequately hold the concentration for as long as it needs to so that it ensures the fire is extinguished. The door fan test, also called room integrity fan test, is used is to predict the enclosure’s retention time should the buildings clean agent suppression system be discharged.

Regular fire hydrant testing ensures the ability to provide water at an acceptable pressure and flow rate for public health and firefighting operations. Most jurisdictions also require hydrant flow tests to design fire sprinkler systems for commercial or residential structures.
