Gas Detection for Confined Spaces

It is important to test the air inside confined spaces for oxygen as well as toxic and flammable gases prior to entry. Confined space gas detector kits use a remote sampling pump to pull a gas sample into the monitor for assessment. This is standard practice before entering any confined space.

Confined spaces are deadly spaces

Worksafe New Zealand defines a confined space as “any area that is not intended for human occupancy and that also has the potential for containing a dangerous atmosphere”.

Examples of places where a confined space gas detector should be used

Confined spaces are large enough for a worker to enter and perform assigned work but have limited or restricted entry and exit and, amongst other things, may contain a hazardous atmosphere arising from chemicals, sludge or sewage.

  • Hazardous gases that displace breathable air, e.g. carbon monoxide, hydrogen sulphide, oxygen deficiency, etc.
  • Toxic gases that are flammable and/or explosive, e.g. oxygen concentration, benzene, solvents, etc.

To comply with the Health and Safety at Work Act 2015 (HSWA) and, most importantly, to protect workers against man-down incidents, you must evaluate confined spaces before entry. All confined spaces where flammable gases, toxic vapours and abnormal oxygen content are possible should be tested before entry.
