Explosion protection - Requirements of process measurement technology for the protection of plants against the occurrence of explosions
As early as the 19th century, explosions in the mining sector became more frequent due to industrialisation. Even then, the causes of explosions had to be investigated and researched with the aim of protecting people, the environment and plants. Mine gas and coal dust could ignite on open flames, sparks or hot surfaces and trigger an explosion. Regulations were derived from these findings to prevent explosions. Of course, the danger of an explosion still exists today, because wherever flammable substances in the form of gases, vapours, mists or dusts meet air and an ignition source, an explosion can occur with devastating consequences. Explosion protection to safeguard industrial plants is therefore still a top priority!

Field devices used in potentially hazardous areas must undergo different certification processes, depending on the economic area. Based on the three large economic areas of Europe, North America and China as well as the countries Australia and New Zealand, we show the respective certifications and their complexity.
