Confined Space and Gas Testing

Confined Space means an enclosed or partially enclosed space that:

  • is at atmospheric pressure when anyone is in the space; and
  • is not intended or designed primarily as a workplace; and
  • could have restricted entry to, or exit from, the place; and
  • is, or is likely to be, entered by a person to work; and
  • at any time, contains, or is likely to contain: an atmosphere that has potentially harmful levels of a contaminant; an atmosphere that does not have a safe oxygen level and anything that could cause engulfment.

All hazardous spaces should be thoroughly assessed prior to any persons entering. Some of the most common confined spaces that people are rescued from are:

  • storage tanks, tank cars, process vessels, pressure vessels, boilers, silos and other tank-like compartments
  • pits and degreasers
  • pipes, sewers, sewer pump stations including wet or dry wells, shafts and ducts
  • Shipboard spaces entered through small hatchways or access points, cargo tanks, cellular double bottom tanks, duct keels, ballast or oil tanks and void spaces.

In the event of explosions in public spaces this list expands dramatically.

The work activities undertaken in a confined space are often indicative of the hazards which may be present. For example, the use of hazardous substances can bring about hazards such as oxygen deficiency, atmospheric contaminants or flammable atmospheres.

In a time of crisis, timing is crucial. In as little as four minutes without oxygen a person in a confined space will likely suffer asphyxia resulting in either brain damage or death.

AML Risk Management can provide an onsite specialist rescue services in times when such incidents occur. Before any engagement, AML Risk Management will be on-site to perform all the required preliminary testing – gas testing, entry/egress access points, ventilation requirements, breathing apparatus testing, protective clothing and equipment adherence, all rescue equipment certified and adherence to Australian OH&S compliance.

The urgent need to rescue someone from a confined space often leads to an ill-prepared rescue attempt. Two-thirds of all of deaths occurring in confined spaces are attributed to people attempting to rescue someone else.

AML provide a professional end to end Emergency Response Service that engages from any incident or accident through to rescue, resuscitation or retrieval.
