Ensuring worker safety is a top priority, and gas detection is vital for preventing exposure to harmful levels of toxic or explosive gases.

Inadequate detection can lead to serious health problems, including respiratory issues, poisoning, or even fatalities.

It also mitigates the risk of fire or explosion caused by flammable gases.

Gas Detection Regulations in the UK

Gas detection is tightly regulated in the UK to ensure worker safety.

The Health and Safety Executive (HSE) sets out the guidelines, and EH40/2005 lists workplace exposure limits (WELs) for numerous hazardous substances, including gases.


Adhering to these limits is crucial for maintaining a safe working environment.

Some common gases and their UK WELs include:

Carbon Monoxide (CO): WEL of 20 PPM over an 8-hour time-weighted average (TWA)

Hydrogen Sulphide (H₂S): WEL of 5 PPM over an 8-hour TWA

Methane (CH₄): Though methane is not toxic, its explosive properties make it a key gas to monitor.

The Personal Surveyor (PS200 Series) provides unrivalled protection in confined space applications. It features audible and visual alarms in the event of exposure to flammable or toxic gases.

Detecting and displaying up to 4 gases simultaneously, the GMI PS200 is suitable for a host of applications in a variety of industries. The PS200 4 gas detector can be configured to detect a combination of Methane, Oxygen, Carbon Monoxide, Hydrogen Sulphide, as well as other flammable gasses.
