The peak pressure the explosion can reach is known as the maximum explosion pressure (Pmax). These two parameters are commonly referred to as explosion indices, and are crucial for the correct design of explosion protection equipment. After the rapid increase in pressure (and temperature) caused by the expanding gases, a vacuum is created which can suck objects back towards the explosion. This is known as a blast wind, and can cause additional damage to structures following the initial overpressure. For example, it can cause glass windows to shatter in the opposite direction of the explosion overpressure, and is something that should be considered if investigating an explosion. https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/5a596794-8072-4ddb-806d-ab61984177f8/Flame+Speeds+Graphic.png Technical Articles - What Is an Industrial Explosion? - Explosion Flame Speed Deflagration: A subsonic flame front travelling relatively slowly through the flammable atmosphere, producing moderate pressure rise. Deflagration to Detonation Transition (DDT): The flame accelerates rapidly due to congestion, creating significantly higher pressures. Detonation: A supersonic combustion wave coupled with a shock front, generating extremely high overpressures and destructive forces. https://www.dsearuk.com/articles/heat-pump-and-refrigeration-system-dsear-requirements monthly 0.5 2026-08-05 https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/c34ec924-5d9f-4d2d-ad20-22a76345080b/Heat+Pump Technical Articles - DSEAR Requirements for Heat Pumps and Refrigeration Systems - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.dsearuk.com/articles/legacy-non-atex-equipment-in-dsear-hazardous-zones monthly 0.5 2026-08-05 https://www.dsearuk.com/articles/selectingatexequipment monthly 0.5 2026-08-05 https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/691affed-5353-498a-9e51-45a728c7c06f/Mark+for+Explosion+Protection+-+Yellow.png Technical Articles - How to Select ATEX Equipment - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/ce8dbf49-538a-4e15-ac95-d4bb225a0fe9/ATEX+Equipment+-+Table+1.png Technical Articles - How to Select ATEX Equipment - Zone and Equipment Category https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/ff63606a-2359-4566-ae06-5c8d337b6978/ATEX+Equipment+-+Image+1.png Technical Articles - How to Select ATEX Equipment - EPS Equipment Marking Therefore, the minimum ATEX marking required in line with the EPS legislation for an item of non-mining equipment suitable for used in an area classified as Zone 1 or Zone 2 is as shown. https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/7792420c-ae05-45be-b619-b942ed455d52/ATEX+Equipment+-+Table+2.png Technical Articles - How to Select ATEX Equipment - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/0ef3ba8d-083b-48c2-b91d-69961d826f18/ATEX+Equipment+-+Image+2.png Technical Articles - How to Select ATEX Equipment https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/6cc8b15f-5ced-440b-83cf-cfd72e181f42/ATEX+Equipment+-+Table+3.png Technical Articles - How to Select ATEX Equipment - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/0894f700-c0d4-4df3-8593-4c7de6653554/Special+Conditions+Certificate.png Technical Articles - How to Select ATEX Equipment - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://www.dsearuk.com/articles/what-is-hazardous-area-classification monthly 0.5 2026-08-05 https://www.dsearuk.com/articles/what-is-a-dsear-basis-of-safety monthly 0.5 2026-08-05 https://images.squarespace-cdn.com/content/v1/64b05ebd21b30819dc091469/3d8eb3e2-0802-4be0-b83d-c1a04484aaf9/Engineering+Hierarchy+of+Controls Technical Articles - What is a DSEAR Basis of Safety?
