Inspection of Fire Suppression Cylinder
The requirement of Inspection of Fire Suppression Cylinder is in the following:
1.Fire suppression cylinder should be inspected at least once a year. Normally the volume of the fire extinguishing agent inside cylinder is obtained by weighing cylinder with scale. But it will be much more convenient and efficient to use portable liquid level indicator to find liquid level of fire extinguisher inside cylinder. If leakage is more than 10%, find out the reason, repair and maintain .
2.Once fire suppression cylinder is used, refill it.
3.All fire suppression cylinders must must take performance test once two years or according to the regulated frequency by manufacturer. Change the fire extinguishing agent if it goes bad. Clean the inner part of cylinder and inspect every time when changing fire extinguisher. Visible rust is not allowed to be on inner surface of cylinder.
4.Dry powder fire extinguisher must take performance test once a year or according to the regulated frequency by manufacturer. Dry powder fire extinguisher must be changed every 4 years. If extinguisher lumps or has 10% weight loss, it should be replaced.
5.Large mobile fire extinguisher normally refers to 45L, 135L or larger foam extinguisher. (In sand carrier, 45L wheeled fire extinguisher is very common.During inspection, last inspection date should be noticed. )
