Räjähdyssuojella

Räjähdyssuojella is a Finnish term that translates to "explosion protected" or "explosion proof" in English. It refers to the design and construction of equipment and electrical installations intended for use in hazardous areas where flammable gases, vapors, dusts, or fibers may be present. These environments pose a risk of ignition, and explosion-protected equipment is designed to prevent such ignition from occurring.

The principle behind explosion protection is to contain any potential explosion within the equipment or to prevent the atmosphere from reaching an ignitable concentration. This is achieved through various methods, including robust enclosures that can withstand internal explosions, sealing to prevent the ingress of flammable substances, and limiting the temperature of exposed surfaces. The specific type of protection employed depends on the nature of the hazardous atmosphere and the potential ignition sources. International and national standards, such as ATEX in Europe, define the requirements for explosion-protected equipment. Using correctly rated and installed explosion-protected equipment is crucial for ensuring safety in potentially explosive environments and preventing catastrophic incidents.
