A gas leak detector is used to alert the user to a suspected gas leak or high levels of gas.
These gas detectors can be used to detect most combustible gases, all those used in plumbing, heating and other similar applications. These include methane, propane, butane, ethanol, ammonia and hydrogen.
A gas detector can be used when a gas leak is suspected or for checking that a new installation is sealed and complete. Combustible gas detectors are not a continuous monitor for gas leaks: they are used only when needed or for interval checks.
They can be used in professional and DIY applications.
Whilst you do not need any professional training to use a gas detector, anyone working on gas appliances in the home or elsewhere must be on the Gas Safe Register. It is a legal requirement that a Gas Safe Register ID card must be carried by all those practising gas applications.
