Can such a fire extinguisher still be used?
Thread Content
A dry powder fire extinguisher that has been used once needs to be refilled. However, a few days after refilling, the pressure gauge shows a reading in the yellow zone; yet the extinguisher still functions normally. Is it okay in this situation? Do I need to reinstall it or replace it? Please share your opinions.
Check whether the pressure continues to drop; if it drops into the red zone, refilling is necessary, or a pressure test should be conducted to check for any other issues
It can still be used now, but it won’t work if the pressure is below the red zone
Fire extinguishers are not ordinary production facilities or devices. Emergency backups must be kept in good condition; therefore, for both safety inspection standards and security requirements, such a practice should no longer be used.
It seems there’s no definite conclusion as to whether it’s safe or not.
It can continue to be used within the green and yellow zones; if it approaches the red zone or has reached it, it needs to be replaced or refilled.
Under tracking management, once it is confirmed to be in the red zone, it can no longer be used
Thank you all for your responses. We check it once a month, and it has been in the yellow zone for two consecutive times recently.
A fire extinguisher must not be used once it reaches the red zone; it can still be used at present, but it needs to be monitored regularly. Use should be stopped once it reaches the red zone, after which it needs to be refilled.
Red areas indicate insufficient pressure, green indicates normal levels, and yellow indicates high pressure
When the pointer drops into the red zone, it needs to be refilled!

Filling requires specialized institutions to carry out; it can’t be done just anywhere. It’s certain that when the pressure reaches the red zone, it can no longer be used.
Filling must be done by a specialized facility; once it is confirmed that refilling is possible, the container can be refilled, otherwise it has to be replaced with a new one.
It can be used again now, but if the pressure indicator is in the red range, it cannot be used and should be refilled with powder.
As long as it is not in the red zone, it can continue to be used as long as it is still within its valid period. This post was last edited by lyhh9024 on 2009-3-9 at 15:38.]
According to the regulations, dry powder fire extinguishers need to have their contents replaced once a year. Since you have just had it refilled, it should still be within its useful life. If the pressure inside the extinguisher is normal, the pointer should be in the green middle zone; if it reaches the yellow zone, it means there is excessive pressure. You can observe it for two days to see if the pressure drops back to normal. As per the rules, if there is excessive pressure, the extinguisher still needs to have its contents replaced, though it can still be used. However, if the pointer reaches the red zone, it indicates that there is no pressure left, and the extinguisher cannot be used any longer; it must then be refilled. One thing to keep in mind is that as long as it is still within its useful life, replacing the contents is free of charge
Yes, it is filled at a specialized facility.
? ? Are there any relevant regulations? We have to pay every time we go; it’s not free.
It can continue to be used within the green and yellow zones; if it approaches or enters the red zone, it needs to be replaced or refilled. To determine whether there is a problem with the pressure gauge, it’s best to check the degree of pressure drop, as temperature can also affect pressure changes.
