Explosion lights and lampshade should automatically cut off the power before opening. However, because the locking device is more complicated and it is not easy to achieve, most 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 refers to the explosion -barrier structure). , And can quickly open the loud lanterns. Pay attention to this.

When replacing the bulb (tube), the explosion-proof lamps should be properly protected and not damaged; the explosion surface of the cleaning should be coated with phosphorus or 204-1 rust oil, and other paint is strictly prohibited; There must be no rust layer on the surface. If there is a slightly rust, there should be no hemp surface after cleaning.

The sealing ring for dustproof and waterproof must be guaranteed intact, which is very important for adding safety 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 during maintenance.
