Matters needing attention
1. During transportation and storage, fire extinguishers should be protected from inversion, rain, sunlight, strong radiation and contact with corrosive substances.
2. The storage environment temperature of fire extinguishers should be within the range of-10-45℃.
3. The place where the fire extinguisher is placed should be kept dry and ventilated to prevent the cylinder from being corroded by moisture. Sun exposure and strong radiant heat should be avoided to avoid affecting the normal use of fire extinguishers.
Extended data:
Once the fire extinguisher is turned on, even if it is not sprayed much, it must be refilled according to the specified requirements. Refilling shall be carried out by professional maintenance departments in accordance with the requirements and methods specified by the manufacturer, and the variety, weight and driving gas pressure of the extinguishing agent shall not be changed casually.
If there is a problem with the fire extinguisher after functional inspection, it must be repaired by a qualified maintenance unit, and the damaged parts and gas cylinders should be replaced for water pressure test, and the fire extinguishing agent and driving gas should be refilled.
Maintenance units must strictly implement the fire extinguisher scrapping system. Every five years and before refilling, the main pressure parts of the fire extinguisher, such as the head and cylinder, should be subjected to water pressure test, and only those that pass the test can continue to be used. After the test, the inner wall shall be dried and inspected in time, and there shall be no obvious corrosion. If the water pressure test is unqualified, welding repair is not allowed.
