Explosion lights and lampshade should automatically cut off the power before opening. However, because it is more complicated and difficult to achieve, most explosion -proof lamps only set a warningboard such as "strictly prohibited to open" in the shell. And because the surface temperature is still high after the light bulb is powered off. If you open the lampshade immediately, there is still a danger of litting the explosive gas mixture (mainly referring to the structure of the next door). You can quickly open the lamps of the lid to pay attention to this. Some explosion -proof fluorescent lights have a locking mechanism that is turned on and power -off, which provides convenience and security for the maintenance work. Because the fluorescent lamp is a cold light source lamp, there is no surface high temperature, and the lid can be turned on immediately after power off.

       When the explosion-proof lamp is replaced by the bulb (tube), the explosion-proof lamps should be properly protected and shall not be damaged. There must be no rust layer on the explosion surface. If there is a slightly rust, there is no hemp surface after cleaning. The sealing ring for dustproof and waterproof must be guaranteed intact, which is very important for the increased explosion -proof lamps. If the sealing ring is severely damaged, replace it with the sealing ring of the same specifications and the same material, and replace the entire lamp if necessary. Pay attention to whether the lampshade is intact. If there is a rupture, replace it immediately.
