Confined Space and Gas Detection

A confined space is one of the most hazardous environments people can find themselves regularly working in. Height Safety Engineers can supply a range of breathing apparatus and gas detection equipment to ensure your team are kept safe.

With restricted movement, potentially dangerous atmospheres and limited access, confined spaces are one of the most hazardous places people can be working in. A confined space can be anything from working inside a tank, a trench or enclosed roof space to a culvert, silo and even the inside of a box girder.

Height Safety Engineers can supply a wide range of confined space entry and access equipment including tripods, ropes, winches and pulleys as well as breathing apparatus and gas detection equipment to assist those working in confined spaces stay safe in these dangerous environments.

Popular confined space safety equipment

Skylotec Triboc confined space access tripod

Skylotec Triboc

The Skylotec Triboc is a sturdy, adjustable tripod that is allows the lifting of loads and people into and out of confined spaces. It is also able to be used during confined space rescue, and is rated to lift two people at once. The Triboc’s maximum material load is 500kg.

MSA Altair 5X multigas detector for use in confined space.

MSA Altair 5X Multigas Detector

This gas detector is capable of measuring up to six gases simultaneously, enabling the user to accurately determine the safety of the atmosphere in a confined space. It can measure oxygen, carbon monoxide, carbon dioxide, hydrogen sulphide, sulfur dioxide, chlorine gas and more.

SpanSet Winch SVLWB used for confined space access.

SpanSet Winch SVLWB

The SpanSet SVLWB series winch is used in HSE’s training centres. This winch is available with 20m and 30m length cables and can be used to raise and lower workers in conjunction with secondary fall protection like a fall arrest block. The galvanised cable can be supplied in stainless steel if required.

About confined space safety

Australian Standard AS2865:2009 defines a confined space as an enclosed or partially enclosed space that is not intended or designed primarily for human occupancy. In these areas, there are often risks of one or more of:

  • Oxygen concentrations outside the safe range, either higher or lower.
  • Concentration of airborne contaminants that can cause impairment, loss of consciousness or asphyxiation.
  • Flammable airborne contaminants that ignite or explode causing injury.
  • Suffocation or drowning from engulfment in either a stored free-flowing liquid or rising levels of liquid.

When it comes to working in and around these areas, it is important you have the equipment you need not just to complete your work safely, but to respond to any potential emergency should it arise.

Gas detection equipment can be used to determine if an atmosphere within a confined space is safe. They can also provide ongoing monitoring of an atmosphere and provide warnings if the air is becoming dangerous, allowing workers to exit the confined space before an emergency arises.

In areas where the atmosphere may be hazardous, or has become hazardous, breathing apparatus can be used to allow safe access to work, or effect a rescue in the event of an emergency. Breathing apparatus usually takes the form of a sealed face mask and air supply and is commonly referred to as SCBA (self-contained breathing apparatus).
