Gas and vapour detection play a crucial role in any risk assessment associated with confined space entry and hot work activities.

A recent safety alert from the HSE highlighted the importance of choosing and testing the right equipment when carrying out work related to gas detection. This follows a fatal incident which involved hot work activities.

In this case, hot work commenced with the understanding that there was no dangerous gas or vapour present. This was due to an unforeseen equipment failure which ultimately led to an explosion and a fatal injury.

Following the subsequent investigation, the inner surface of the sample tube was deemed to be a significant contributor to the failed detection as it had absorbed the gas before it could reach the detector.

Workers need to be aware that specific hazards cannot be eliminated or controlled in many cases, and suitable equipment combined with safety arrangements must be implemented prior to work commencing.

Confined spaces pose their own unique set of risks. In many cases, workers are exposed to poor ventilation, hot conditions, lack of oxygen, as well as the build-up of vapours and gases.

Before entering a confined space it is advised that all equipment is safely tested before any work commences, especially when testing for potentially dangerous gases.

We provide a selection of Authorised and Competent Person Confined Space training courses. Our City & Guilds accredited courses provide support to those who are appointed for these positions and to ensure a Safe Systems of Work is in place.
