Commercial gas safety tips in support of 

Gas Safety Week 17th-23rd September 2018 

Commercial gas


Domestic gas safety is important for so many of us with gas-fired boilers, cookers and heaters in our homes. But let’s not forget, commercial gas safety matters too…

In the past year alone, phs Compliance carried out gas safety checks on more than 20,000 commercial gas appliances. 11% of appliances inspected were defective.

Many defects and leaks can be avoided if correct maintenance is carried out. Scheduled planned maintenance not just optimises the safety of commercial gas installations – it reduces the risk to business operations and revenue through downtime. Annual planned maintenance often significantly extends the safety lifecycle of gas-fired equipment too.

Read on to find out more about common defects, how to avoid them, and our top safety tips for commercial gas installations.

Common defects found in commercial gas safety

  • Appliance housing – what should and shouldn’t be boxed off? It’s often the case that boiler rooms are used as storage areas. Be alert to the potential for obstructing ventilation or emergency access. Manufacturer’s instructions should always be followed to ensure that the correct clearances are adhered to for gas appliances located near combustible materials
  • Extract ductwork and ventilation systems in catering kitchens. ‘Deep clean’ best practice should follow industry-standard guidelines as laid out in BESA’s TR19 Internal Cleanliness of Ventilation Systems guidelines. If these standards are met in annual maintenance practice, grease deposits can be avoided and therefore risk of fire is reduced
  • Flue and pipework integrity is paramount to gas safety. The nature of flue gases cause seals and flue material to degrade over time. There is a risk - if left unchecked - that flue gases can escape into the room. Pipework whether it relates to gas, cold water mains or heating circulation can also be at risk of failing if not checked on a regular basis, particularly if it is exposed to extreme weather conditions. Simple regular checks by registered gas Safe engineers ensure the integrity and long life of pipework, and thereby ensure the safety of the installation
  • Plant or meter loading good safety practice. Before installing additional appliances, good practice checks are needed to ensure that the gas meter and supply pipework to the property fully support guideline pressure loss and gas pressures for available appliances. As well as a comprehensive survey, a gas pipework sizing exercise is recommended to ensure that new appliances will operate safely and to manufacturer’s instructions.


Top safety tips for commercial gas installations

1: Avoid undersized pipework or meter. Ensure your registered installer conducts a gas pipework survey to confirm that existing pipework is suitable for adding an appliance and that your meter capacity is not overloaded.

2: Avoid gas appliance locations being used for storage. This blocks necessary ventilation and can create risk from accidental fires.

3: Don’t skimp on annual gas maintenance. Use experienced accredited suppliers within a wider maintenance provider framework. You’ll get the expert service you need, as well as operating spend cost-efficiencies.
