In the event of a fire, the fire extinguisher plays an important role, and it is usually necessary to check its effectiveness. What does the fire extinguisher effectiveness check include?
I. Check the pressure index of the fire extinguisher. The pressure gauge of the fire extinguisher is divided into three areas: Red area: indicates that the dry powder pressure in the fire extinguisher is small, and it may be impossible to spray or has failed. Green area: indicates that the pressure is normal and the fire extinguisher can be used normally. Yellow area: indicates that the pressure in the fire extinguisher is too high, and there is danger of explosion and explosion.

Second, the appearance check, the aluminum seal should be complete, the pressure gauge pointer should be green, the visible part of the fire extinguisher should be intact, no corrosion, visible parts of the fire extinguisher should be complete, no loosening, deformation, corrosion and damage, the nozzle and spray hose Complete and non-blocking.
Third, the tightness check and strength check, the internal pressure of the head and the simplified parts and the head of the connection parts, should be subjected to a hydraulic test in accordance with regulations, there should be no leakage and visible deformation during the test.
