Electrical Switch Room Rubber Matting


As one of most hazardous workplaces, high voltage environments like Electrical Switch Rooms expose employees to possible electric shocks, electrocution, fires and even explosions. These are usually caused by switchgear failures due to various reasons such as:

  • Loose and faulty connections
  • Insulation breakdown
  • Water intrusion or immersion
  • Breaker racking
  • Defective ground fault protection

To control the hazards within the workplace, every business owner must assess the risks beforehand and be knowledgeable on the ways to manage, inspect and maintain their operations - as failure to comply with the Electrical Safety Regulations, as established by the Health and Safety Executive (HSE), may result in legal action and financial losses.

How does rubber matting work in high voltage environments?

Rubber matting is an essential element to boost operational safety in Electrical Switch Rooms. Well-known for its electrical insulating properties, switchboard matting can protect against fatal shocks by reducing potential risks within the facility.

When suitably applied to the area, rubber mats can safeguard workers when the electrical current travels from the equipment to the ground. This effective safety solution is also widely used in other areas such as:

  • Plant rooms
  • Lift control gear rooms
  • Sites with live equipment

Electrical rubber matting is made with different levels of protection to promote safety within the workplace.

Industry standards

Since accidents are a constant threat in Electrical Switch Rooms, it is vital that electrical rubber matting is compliant with industry standards.

BS EN 61111:2009 (all classes)

Under BS EN 61111:2009, the electrical rubber matting will go through a much more extensive testing process compared to the previous BS 921:1976 standard. Rubber matting is classified according to the maximum working voltage.


Maximum Working Voltage


1000V AC


7500V AC


17000V AC


26500V AC


36000V AC


Rubber matting that complies with BS EN 61111:2009 also provides these invaluable features:

  • Lightweight
  • Oil resistance
  • Flame retardant
  • Acid resistance

BS 921:1976

BS 921:1976 is a previously acknowledged British Standard that has now been replaced by BS EN 6111 2009. Rubber matting that complies with the old standard is still available up to 650V working insulation.

ASTM – Standard Specification for Rubber Insulating Matting

The ASTM states the manufacturing processes as well as the minimum chemical, physical and electrical properties required for rubber insulating matting.


VDE is a standard that runs a performance testing process to identify the dielectric matting parameters, surface and volume resistivity. It will also establish the electrical breakdown field strength of the matting.

We are proud to say that Coruba’s range of electrical safety matting has been comprehensively tested in accordance with the industry standards – assuring reliable protection in high voltage areas. For product questions and enquiries, you may contact us on 01702 560194.
