Importance of Roadside Gas Meter Box Ventilation

Roadside gas meter box ventilation is an important issue to consider when investing in GRP housings for your project. We look at what the law says on gas ventilation and fire safety and how you can be certain that the gas box you’re purchasing is safe to use.

What Does the Law Say?

All roadside gas meter boxes must conform to a strict set of rules when it comes to ventilation. These laws and regulations are put in place to ensure gas housings are safe both for employees using them and the general public.

A minimum of 3% ventilation is required as directed by PRS/35 as required by the national grid gas. This ensures all GRP gas boxes have enough ventilation to prevent the risk of explosion.  Without this, boxes are not deemed safe to use and should not be placed in public areas or around work sites.

Another legal requirement which ensures gas boxes can run safely at full capacity is the British Standard 476 part 7 class 2. This standard refers to how quickly a flame will spread if a fire occurs. To achieve this classification, GRP gas boxes must ensure that in the case of fire, the spread of flame is no larger than 215mm in the first one and a half minutes. It also states that the overall spread can be no more than 455mm in total.

Flame spread can be dangerous and pose a serious health and safety risk. A class 2 rating is the safest and most appropriate standard to consider when investing in GRP gas boxes.

Our top priority is stability and safety, which is why our roadside gas meter box ventilation is up to scratch. All our gas kiosks have been fully and rigorously tested to ensure they meet all the above regulations.

Our boxes are highly protected against flame spread thanks to the strong GRP laminate and fire resistant polyester resin that we use in all of our units. Extra strong boxes, with a double skin sandwich made of 18mm thick plywood, can also be designed and built for use in ‘high risk’ areas, where bad weather or vandalism is more likely.

What comes as standard with our gas meter boxes?

  • Multi-layer GRP with encapsulated integral stiffening
  • Glass strand mat reinforcement
  • Optional plywood double skin
  • Units made from fire retarded resin that meet BS 476 part 7 class 2
  • Minimum required ventilation as directed by PRS 35 – National Grid Gas

The quality of your gas boxes matters and with a minimum ventilation of 3% and life expectancy of 25 years on average, a Kingsley Plastic roadside gas meter housing is one you can trust.
