Explosion proof equipment is able to exclude one of the preconditions for an explosion - the ignition source - and is in that way an important contribution to explosion protection. In domestic areas, architectural measures ensure that normally an explosive atmosphere cannot be formed. The conscious restriction of these measures, for example the intended, unimpeded flow of flammable gases or a reduction in ventilation can lead to explosions if an ignition source is also present. The easiest and most simple way to understand small and safe explosions is by looking at a gas lighter. When the nozzle of the lighter is opened, it releases a small amount of flammable gas. This gas mixes with the surrounding air, the spark from the flint ignites the mixture, and a weak sound is heard - the burning. Some distance away from the nozzle the proportion of the flammable gas is already so low that the explosion and the flame are restricted to the immediate vicinity of the nozzle. In other words, the design of the gas lighter has ensured that it is safe to use. The effect of an explosion in enclosed spaces and under non-atmospheric conditions - for example under increased pressure - is often more powerful. Just think of the useful application of explosions in vehicle engines. To attain effective explosion protection against non-controlled, unintended explosions linked to disastrous consequences, it is necessary to remove one of the three factors. BARTEC products prevent effective ignition sources from getting in contact with potentially explosive atmospheres. They effectively prevent explosions because the other two factors - the oxygen in the air and often the flammable substance - cannot be reliably and permanently ruled out in workplaces.
