Explosion protection Ensure the highest levels of safety in potentially explosive areas.

Explosion protection (Ex protection) is an essential part of safety technology. It deals with protection against explosions and their effects. Anywhere combustible materials, oxygen, other gases, and ignition sources can interact, smooth production processes and compliance with the requirements for occupational safety and environmental protection must be ensured. Explosion protection is mainly based on European and North American standards and directives, including the ATEX, IECEx, NEC/CEC, and UL certifications and directives.

Of course, the plant engineers and planners of classical chemical industry and petrochemical plants must comply with the legal provisions for explosion protection. However, other industries that may seem non-critical at first glance, such as the food industry, can harbor significant risks. People often assume that explosion protection involves gases that can create an explosive atmosphere, but these can also occur when there is dust.
