HydITEx offers an invention that relates to the field of protection against explosive effects, in particular to limit the effects of an explosion of a hydrogen-air atmospheres in flameproof enclosures "d" designed to accommodate equipment in them, for example, electric, pneumatic, mechanical drives, etc. The method of limiting explosive effects is based on the localization of equipment in an flameproof enclosure "d", in which a protective layer is created, while a protective layer is formed on the inner surface of an flameproof enclosure "d" made of honeycomb coating. The flameproof enclosure "d" contains a housing with a lid connected by screws, inside which normally sparking parts of the equipment are installed, and the inner surface of the housing and lid is covered with honeycomb coating, made with the possibility of scattering a shock wave during an explosion of a hydrogen-air atmospheres inside the flameproof enclosure "d". The inner surface of the case and lid are coated with honeycomb coating. The use of the claimed group of inventions makes it possible to create an flameproof enclosure "d" with high reliability, improved weight and size indicators, and also reduces the impact of an explosion on the equipment placed in it.
