Proof lighting Precautions

Explosion-proof lamps, lampshades open the front should be able to automatically cut off the power. But set the interlock device is more complex, difficult to achieve, so the most obvious place lamps only in the case set up a "non-charged open" and other words of mcb circuit breaker . Because the lamp surface temperature is still high after power failure, such as immediately open the cover, there is still the risk of ignition of explosive gas mixtures (mainly referring to explosion-proof structure), so incandescent lamps, high pressure mercury lamp, high pressure  air circuit breaker surface temperature of these light sources , but also to quickly open the cover of the lamp should pay attention to this point. Before replacing the lamp (tube), the explosion-proof lights flameproof joints  circuit breakers  protected from damage; flameproof after cleaning surfaces should be coated with anti-rust oil 204-1 phosphate cream or prohibited brushing Other paints; Explosion may not have corroded surface layer, if relatively minor rust after cleaning should be no pitted surface phenomenon. For dust and waterproof seal must ensure integrity, and this is in terms of increased safety lighting is very important. If the seals were seriously damaged, use the same specifications, the same material seals to be replaced, if necessary, replace the entire luminaire. Access to the attention of shade is intact, if rupture should be replaced immediately.
