Explosion protection aims to minimise the risk of explosions in hazardous environments by controlling or eliminating potential ignition sources. This is achieved by special devices and installations that prevent flammable gas or dust mixtures from catching fire. For areas with a high risk of explosion, such as chemical plants or mines, such measures are essential to ensure the safety of people and equipment.

Zone 0 - Highest hazard

Area in which explosive gas mixtures occur continuously, for long periods or frequently.

Zone 1 - Medium hazard

Area in which explosive gas mixtures occur occasionally during normal operation.

Zone 2 - Lowest hazard

Area in which explosive gas mixtures do not normally occur or occur only briefly.

Zone 20 - Highest hazard

Area in which explosive dust-air mixtures occur continuously, for long periods or frequently.

Zone 21 - Medium hazard

Area in which explosive dust-air mixtures occur occasionally during normal operation.

Zone 22 - Lowest hazard

Area in which explosive dust-air mixtures do not normally occur or occur only briefly. 

Ex lamps are required in various areas of application to ensure safety in potentially explosive environments. Here are some important areas of application:

•         Chemical plants and refineries
•         Oil and gas industry (drilling platforms, pipelines, tank farms)
•         Mines and pits
•         Paint shops and spray booths
•         Food and animal feed industry
•         Pharmaceutical production facilities
•         Ammunition and explosives depots
•         Grain and animal feed storage facilities
•         Water and waste water treatment plants
•         Textile industry (especially areas with a dust explosion hazard)

These areas require special explosion-proof lamps to minimise the risk of explosions caused by sparks or hot surfaces.
