The importance of having a fire extinguisher at home is self-evident, but if the fire extinguisher cannot be used when it is critical, the loss can be great, so the fire extinguisher must not only be prepared, but also be regularly inspected and replaced. How to check it?
1. Check the appearance of the fire extinguisher, check whether the fire extinguisher is intact, whether the plug and lead seal are still there, whether the hose is broken, and whether the bottom of the fire extinguisher is seriously rusted.
2. Look at the pressure gauge on the fire extinguisher. If the pointer is in the green area, it indicates that it is normal. If it is in the red area, it indicates that the pressure of the fire extinguisher is not working and needs to be replaced or refilled. If the foam fire extinguishing agent manufacturer is in the yellow area, it indicates that the pressure of the fire extinguisher is too high. It can be used normally, but you need to pay attention to it to avoid blasting the fire extinguisher.
3. Look at the date of the fire extinguisher, look at the label of the inspection date on the fire extinguisher, and replace it in time or refill it if it expires. Generally, it is necessary to refill the dry powder fire extinguisher after 5 years of use, and refill it every two years from now on.
