What to do if the pressure of the heptafluoropropane fire extinguishing cylinder is insufficient?
When the pressure of the heptafluoropropane fire extinguishing cylinder is insufficient, it will be reflected on the pressure gauge of the fire extinguishing agent cylinder group, that is, the pointer on the pressure gauge is in the red area. If a fire occurs at this time, the heptafluoropropane gas cannot be quickly and effectively sprayed into the protective area due to insufficient pressure, which may lead to delayed firefighting and ultimately failure, resulting in huge economic losses and personal injury.
There are two types of gas substances in the steel cylinder of the heptafluoropropane fire extinguishing system: heptafluoropropane fire extinguishing agent and nitrogen driven gas. The heptafluoropropane fire extinguishing agent is used for extinguishing fires, and the nitrogen in the heptafluoropropane fire extinguishing system is used to drive the valves related to the heptafluoropropane fire extinguishing system, releasing the heptafluoropropane fire extinguishing agent to achieve the fire extinguishing function. Therefore, if the pressure of the fire extinguishing agent bottle group is low, it indicates that both gases may leak. In this case, a professional fire protection company needs to retest the filling of heptafluoropropane fire extinguishing agent and nitrogen through professional equipment.
