Hazardous Areas

The hazardous area industry involves some of the most challenging operational locations in the world. In oil & gas for instance one of the key hazards to onsite workers and the facility itself is the risk of fire or explosion and how to contain this to prevent a disaster. However many other industries are overlooked and the risk could be around you right now.

Some examples of hazardous areas would include:

  • Oil & gas
  • On and offshore
  • Mills processing wood, paper or flour
  • Storage facilities including aircraft hangers
  • Refuelling pumps and kiosks
  • Distilleries
  • Recycling facilities
  • Bunkers & arms

All very different looking facilities, all posing the same risk, a fuel for a spark or flame to cause a threat to life and the facility.

It is the job of specialised equipment to restrict the risk of the fuel finding its ignition. It’s also imperative to limit the spread whilst supporting critical emergency systems. This gives vital time for a safe evacuation, shutdown procedures and to protect the assets of the facility.

There are dangers, most gases are odourless, most dusts look harmless but as we witness in Beirut in 2020 most storage facilities would not look to pose a threat until it finds its spark.

However, equipment needs power, this gives the fuel its ignition source so every single circuit within a hazardous location must ensure they provide adequate safety to greatly reduce the risk of a potential disaster.

During the selection for any cable system a design engineer considers quality, price and suitability as the buying criteria. However, in the unlikely event of a fire or explosion the chosen system must perform beyond any regular true fire scenario that could ultimately result in fatalities and destruction. This scenario is even more so in a hazardous area. The system needs to contain the explosion, quench the flame and avoid a spark entering the explosive atmosphere. This equipment will only need to perform once, however, when it does it needs to be up to the task. The Wrexham Mineral Cable system is designed and tested to do just that.

Mineral Insulated Cables survives during a fire in excess of 1000°C making it the essential choice for areas which are high risk of flash over fires such as petro chemical plants. The construction of mineral insulated Cables includes a solid copper sheath which is non penetrable and suitable in some of the harshest environments. A bare mineral insulated cable can operate continuously at 250°C and requires no conduits, plastics or polymers to aid fire protection.

Mineral insulted cable can withstand some of the most harshest environments and IP protection can be increased with ease. The Exd cable system from Wrexham Mineral Cables is designed to work in conjunction with all Exd explosion proof environments.

Unlike any other type of hazardous area cable system, Mineral Insulated Cables do not require conduits, curing resins, expensive fittings or complicated terminating processes. One simple twist of our cable gland locking nut produces a total seal to zone 1 & 2 hazardous area applications with a 30 year system warranty.


Wrexham Mineral Cables ATEX approved Mineral Insulated Cables (MICC) cable system can greatly reduce risks.

MIC has been in use commercially since 1937. From a fire performance perspective it has not been surpassed by any other cable system. But combining a mineral insulated cable with an Exd rated cable gland you can achieve a hazardous area cable system suitable for zones 1 & 2 in one easy installation. Fitted with a fully approved cable gland there is no additional conduit needed or waiting for hours at a time for resins to cure. Consequently Exd installations can be achieved in less than 10 minutes.

WMC Quality
The quality and reliability of Wrexham Mineral Cables is recognised worldwide and throughout the electrical industry. Our cables are manufactured to meet British and European standards, achieving endorsements & certifications from many regulatory bodies including BRE - LPCB, the world renowned approvals body for fire performance products. Our LPCB product approval register has been maintained for over 25 years, one of the longest in Europe for any fire performance cable manufacturer. Our Quality system is also approved to ISO9001 through LPCB and our entire facility is run in accordance of ISO9001 Quality system standards.

WMC Approvals
BS5839-1:2017 Enhanced to Clause 26.2 BS EN 50200:2015
BS 8434-2:2003 + A2:2009 BS 8591 & BS 8491 CAT C BS6387:2013 C,W & Z BS 60331
The termination glands are ATEX EExd & IECEx approved to EN 60079 for use in potentially explosive atmospheres under the ATEX Directive 2014/34/EU.

WMC Warranty

For over 30 years we have manufactured in the UK, more than 180 million meters of MICC with ZERO failures in the field.  With this impeccable record you can have complete confidence in our 30 year warranty cable system.

WMC project portfolio extends to many hazardous area sites such as Lower Fars Oil Field Kuwait, Chandra Asri Petrochemical Indonesia & Chemical Industries Colombo Sri Lanka. MICC is essential for the hazardous sector as it survives during fires in excess of 1000°C and is constructed including a solid copper sheath which is non penetrable and suitable in some of the harshest environments. A bare mineral insulated cable can operate continuously at 250°C and requires no conduits, plastics or polymers to aid fire protection.
