When an abnormality is found in the pressure gauge of a foam fire extinguisher, how should the user take emergency measures?

1. Identify abnormalities and respond calmly
When the pressure gauge of the foam fire extinguisher is found to be abnormal, the first thing to do is to stay calm and do not panic. Users should carefully observe the readings of the pressure gauge to determine whether there is a clear deviation from the normal range (such as too low pressure, too high pressure or no display). At the same time, check whether the pressure gauge itself has signs of damage, such as broken pointers, blurred dials, or cracked shells.

2. Assess risks and take good protection
After confirming that the pressure gauge is abnormal, users need to quickly assess the risk level of the current environment. If you are at the scene of a fire or are about to face a fire threat, you should immediately take necessary protective measures, such as wearing protective masks, gloves, etc., and stay away from the fire source as soon as possible to ensure your own safety. At the same time, notify the surrounding people to pay attention to the fire and prepare to take further action.

3. Immediately stop using and isolate the source of danger
Once the pressure gauge of the foam fire extinguisher is found to be abnormal, the fire extinguisher should be stopped immediately and isolated in a safe area to prevent leakage, explosion and other dangerous situations caused by abnormal pressure. During the isolation process, it should be handled with care and avoid violent shaking or collision to avoid aggravating the instability of internal pressure.

4. Seek professional help and troubleshoot
When facing abnormal problems with the pressure gauge of the foam fire extinguisher, users should not disassemble or repair it without authorization, but should promptly contact professional fire equipment maintenance personnel or manufacturers for troubleshooting and repair. Before waiting for professionals to arrive, users can try to obtain preliminary guidance and suggestions by checking the fire extinguisher instruction manual or contacting the fire department.

5. Strengthen daily maintenance to prevent abnormalities
The abnormality of the foam fire extinguisher pressure gauge is often related to inadequate daily maintenance. Therefore, users should strengthen the daily inspection and maintenance of fire extinguishers, regularly check whether the pressure gauge reading is normal, whether the dial is clear, and whether the pointer is flexible. At the same time, pay attention to keeping the surface of the fire extinguisher clean and dry to avoid being affected by corrosive substances or humid environments. In addition, pressure testing and filling should be carried out regularly in accordance with the requirements of the instruction manual to ensure that the fire extinguisher is always in good working condition.

6. Popularize knowledge and improve safety awareness
In order to further improve the public's awareness and response capabilities to abnormal problems with the pressure gauge of foam fire extinguishers, relevant departments and units should strengthen the publicity and popularization of fire safety knowledge. Through fire safety training, drills and other activities, we can enhance the public's fire safety awareness and self-rescue and mutual rescue capabilities. At the same time, we encourage everyone to actively participate in the supervision and management of fire safety and jointly create a safe and harmonious social environment.
