Fire-rated cabinets for ATEX zones - What do I need to know

Within DSEAR, an explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, combustion spreads to the entire unburned mixture.

Safe fire protection with DENIOS fire extinguishers and extinguishing granules

Fire extinguisher obligation in trade and industry

Especially in the workplace, a fire can start quickly. If flammable hazardous substances are in the vicinity, noticeable damage can occur within minutes. Extinguishing blankets can be used quickly in an emergency to save people, but also cooking oil fires in large kitchens or in the home. A fire extinguisher should always be available for equipment, tools and other materials. The regulations of the workplace ordinance (ASR 2.2 "Measures against fires") also apply here. If the workplace consists of several floors, at least one extinguisher must be provided on each floor. If the risk assessment determines that there is an increased risk of fire (e.g. when working with flammable substances), additional fire protection measures must be taken. TRGS 800 (Technical Rules for Hazardous Substances) provides additional information on this.

Fire extinguisher or extinguishing agent: Which extinguisher is suitable?

Fire extinguishers and extinguishing agents must be suitable for extinguishing the materials or substances present in the company according to their assignment to one or more fire classes. These are in detail:

  • Class A: Fires of solid substances, mainly organic in nature, which burn with the formation of embers, e.g. wood, paper, textiles, coal, car tyres.
  • Class B: Fires of liquid substances or substances that become liquid, e.g. petrol, benzene, oils, fats, varnishes, tar, ether, alcohol, stearin, parafin
  • Class C: fires of gases such as methane, propane, hydrogen, acetylene, natural gas, town gas
  • Class D: Fires of metals e.g. aluminium, magnesium, lithium, sodium, potassium and their alloys.
  • Class F: Fires of cooking oils/fats (vegetable or animal oils and fats) in deep-frying and fat-baking equipment and other kitchen equipment and appliances

Practical accessories such as wall brackets, fire extinguisher cabinets or fire extinguisher bonnets make it easier for staff to handle fire extinguishing equipment.
