How to read the fire extinguisher meter

Fire extinguishers are common fire-fighting equipment in daily life. Correct use and regular inspection of fire extinguishers are crucial. However, many people do not know the meaning of the reading of the fire extinguisher gauge (pressure gauge), making it impossible to judge whether the fire extinguisher is in normal condition. This article will introduce in detail how to view the fire extinguisher table, and attach structured data to help you quickly master relevant knowledge.

1. Basic structure of fire extinguisher table

The pressure gauge of a fire extinguisher is usually located on the top or side of the fire extinguisher, and there will be a clear scale area and pointer on the dial. The following is a common structure for a fire extinguisher table:

2. How to correctly read the fire extinguisher meter

1.Observe pointer position: Which color area the pointer on the fire extinguisher gauge points to directly reflects the pressure state of the fire extinguisher. For example, a pointer pointing to a green area indicates that the fire extinguisher is ready for use.

2.Check dial scale: Some fire extinguisher tables will be marked with specific values (such as MPa or psi), and the values can be used to more accurately determine whether the pressure is normal. The following are the pressure ranges of common fire extinguishers:

3.Regular inspection: It is recommended to check the pressure gauge of the fire extinguisher once a month to ensure that the pointer is always in the green zone. If the pointer points to the red or yellow area, it should be replaced or repaired in time.

3. Common problems and solutions to fire extinguisher tables

1.The pointer points to the red area: It may be that the fire extinguisher is leaking or has not been used for a long time, resulting in insufficient pressure. The solution is to contact a professional agency to refill or replace the fire extinguisher.

2.The pointer points to the yellow area: It may be that the ambient temperature is too high or overfilling causes the pressure to be too high. The fire extinguisher should be placed in a cool place or contact a professional to adjust the pressure.

3.Dial is blurry or damaged: If the dial cannot be read clearly, the fire extinguisher should be replaced immediately to avoid misuse due to inability to judge the status.

4. Precautions for using fire extinguishers

1.Check pressure gauge before use: Make sure the fire extinguisher is in working condition to avoid being unable to use it in an emergency.

2.Correct operation: When using a fire extinguisher, stand upwind and spray at the root of the fire source.

3.Regular maintenance: Fire extinguishers require regular inspection and maintenance, generally a comprehensive inspection every 12 months.
