Explosion Protection

Explosion Protection


The presence of an explosive atmosphere (vapours of flammable liquids or combustible dusts in suspension) combined with an ignition source (such as static discharge or friction due to moving metallic parts, etc.) causes an explosion, event more rare than a fire, but surely more serious in terms of human losses and damages to whole industrial plants.

So it is extremely important to adopt the minimum safety measures to prevent an explosion (cleaning in order to eliminate dust clouds or dust layers, use of anti-static materials, check of the correct bonding and earthing of the equipment, use of electrical equipment EX marked that is suitable to be used in explosive atmospheres, etc.)

Moreover, when the explosion risk cannot be eliminated, it is very important to adopt the proper protection measures and isolate the explosion wherever that risk may be present (tanks, filters, deposits, conveyors, etc.) All explosion prevention and protection equipment must be ATEX approved.

A good risk analysis and hazardous areas classification are the first fundamental steps in order to assess the real hazard that an industrial plant is subjected to. No matter the sector, all industrial fields are involved to some extent: food, beverages, chemical, oil & gas, pharmaceutical, cosmetic, etc.

Static Earthing Control

Automatic static control systems with interlock capacity for the correct earthing of road vehicles, intermediate bulk containers, small drums, big-bags, parts of machinery, etc.

Spark detection and extinguishment

In pneumatic transports and mechanical conveying systems carrying combustible materials, flying sparks are often causing fires and filter explosions. In order to avoid this risk, it is necessary to monitor conveying and extraction systems for flying sparks and to safeguard them by spark extinguishing systems.

Temperature detection for ATEX zones

In order to monitor the temperature inside the process (pipeline, filters, silos, etc.) it is possible to use ETEX heat detection system which is suitable to all EX zones (0, 1, 2, 20, 21, 22) and for both surface industries and mines.

In order to avoid that an explosion inside the equipment propagates through the pipeline to other process sections creating “domino effect” proper devices / systems for explosion isolation must be applied:

Chemical barrier (explosion suppressors)

Mechanical barrier (fl ap valve, Float Valve, Quench Valve, etc.)
