The explosion-proof lamp and lampshade should be able to automatically cut off the power supply before opening. However, because the interlocking device is more complicated and difficult to achieve, most lamps only have warning signs with the words "It is strictly forbidden to open with electricity" on the outer casing.

And because the surface temperature of the bulb is still very high after the power is turned off, if the lampshade is opened immediately, there is still the danger of igniting the explosive gas mixture (mainly refers to the flameproof structure), so incandescent lamps, high-pressure mercury lamps, and high-pressure sodium lamps are light sources with high surface temperature. , and can quickly open the cover of the lamp should pay attention to this.

When replacing the bulb (tube), the flameproof joint surface of the explosion-proof lamp should be properly protected and not damaged; the cleaned flameproof surface should be coated with phosphating paste or 204-1 anti-rust oil, and other paints are strictly prohibited; There should be no rust layer on the surface. If there is slight rust, there should be no pockmarked surface after cleaning.

The sealing ring used for dustproof and waterproof must be kept intact, which is very important for the increased safety lamps. If the sealing ring is seriously damaged, replace it with a sealing ring of the same specification and material, and replace the entire lamp if necessary. When overhauling, pay attention to whether the lampshade is in good condition. If it is broken, replace it immediately.
