What should you pay attention to when storing dry powder chemical extinguisher

In daily use and maintenance of dry powder chemical fire extinguishers, the storage process is crucial. A reasonable storage method can not only extend the service life of the fire extinguisher, but also ensure its effectiveness in emergency situations. Relevant safety standards and operating procedures must be strictly followed during the storage process to avoid safety hazards and performance degradation caused by improper storage.

First of all, the choice of storage location should focus on dryness and ventilation, and stay away from fire and heat sources to prevent the impact of humid environment on the dry powder inside the fire extinguisher. Moisture may cause dry powder to clump and adhere, and in severe cases it will block the nozzle, affect the spray effect, and even cause the fire extinguisher to fail. To prevent water vapor from invading, the storage area should have a good drainage and ventilation system to avoid the accumulation of accumulated water and moisture, and ensure that the fire extinguisher is always in a dry state.

The storage environment also needs to be kept away from corrosive substances and harmful gases to avoid damage to the equipment structure by chemical corrosion. Chemical corrosion not only weakens the mechanical strength of the fire extinguisher, but may also lead to safety accidents such as leakage or explosion. Therefore, the storage place should avoid contact with corrosive substances such as strong acids, strong alkalis, oils, and solvents. Especially in industrial environments, the storage location should have clear markings and isolation measures to ensure safety. In addition, the storage area should be avoided by vibration, impact and mechanical damage to prevent external forces from deforming or damage to the pressure vessel, thereby affecting the sealing and performance of the fire extinguisher.

A reasonable storage space layout is an important factor in ensuring that fire extinguishers are easy to access and regularly inspected. The fire extinguisher should be stored vertically to avoid being inverted or horizontally to avoid poor flow of dry powder or clogging the nozzle. During storage, appropriate spacing should be maintained for easy inspection and maintenance, and avoid excessive stacking and poor ventilation or difficulty in access. The storage location should be marked with obvious signs to facilitate quick identification and access by staff, especially in emergency fire situations to achieve rapid response. For fire extinguishers of different capacity and types, they should be stored reasonably according to their specifications to avoid overloading or stacking to maintain good stability.

During the storage process, regular inspection and maintenance are also indispensable to ensure the integrity of the fire extinguisher. During storage, regular inspections should be carried out to check whether the pressure gauge is within the normal range, whether the shell is intact, whether the nozzle is blocked, and whether the label is clearly visible. Especially after long-term storage, pressure detection and functional testing should be carried out to ensure that the fire extinguishing agent does not fail due to moisture absorption or other reasons. If leakage, rust, deformation or other abnormal situations are found, repair or replacement measures should be taken in a timely manner to avoid the risk of equipment failure when a fire occurs.

The storage environment must also comply with the requirements of relevant regulations and industry standards. For example, fire safety regulations put forward clear regulations on the storage location, quantity, marking, channel width, etc. of fire extinguishers. The storage area should be equipped with obvious safety signs and warning signs to remind personnel to pay attention to safety and avoid misoperation. For the storage of large or multiple fire extinguishers, a detailed management system should be formulated to ensure that each equipment can be properly managed and maintained in a timely manner.
