Diving & breathing apparatus servicing

Safety. It’s the first and perhaps most obvious reason for why you need to regularly service your breathing apparatus – (SCUBA, SSBA, SCBA and CABA).

Your breathing apparatus keeps you alive underwater and in non-respirable environments. So in order to keep you safe, it needs to function correctly. Small issues with un-serviced equipment don’t usually lead to catastrophic failure, but often it’s a small issue which leads to much bigger problems arising. Regular servicing is a simple and smart way to minimise this risk.

Servicing your current equipment with a good servicing regime or original equipment manufacturer (OEM) is the best way to maintain your equipment correctly. It is also a more sustainable option than purchasing new equipment. Good servicing will allow you to maintain your equipment correctly and ultimately, give you a longer service life with fewer problems.

What is a breathing apparatus

A Breathing Apparatus (BA) is an item of safety equipment which allows the wearer to work safely in an IDLH atmosphere by providing air to a sealed mask from a stored container or cylinder. The cylinder can either be carried by the user or stored at a remote location with the air being supplied via an airline. A BA typically has 3 main components: a high-pressure cylinder (e.g. 200bar to 300bar), a pressure regulator and an inhalation connection (mouthpiece, mouth mask or face mask) connected and mounted to a harness backpack.

What is a breathing air cascade system

Cascade systems are deployed to ensure personnel at risk from exposure to Hydrogen sulfide (H2S) have a safe and reliable supply of breathable air. Outlet manifolds and plug-in points are located in critical areas to allow workers who undertake essential operations (such as emergency well control) to continue working for an extended period. This extended period is generally beyond the 30-minutes offered when utilising Self Contained Breathing Apparatus (SCBA). The use of a cascade system ensures that essential crew have breathable air available throughout the operation which ensures, their safety.

What is a gas detector?

A gas detector is a device that detects the presence of various gases within an area. It is usually as part of a system that warns you about harmful gases in the air.

There are many types available ranging from simple portable single gas detectors to fully fixed gas detection systems covering large areas and incorporating many fixed sensors. Gas detection equipment is categorised into 4 main groups.

H2S gas detection systems and personal gas detectors are designed to provide the earliest possible warning of the presence of H2S. These systems allow the personnel at risk of exposure to take the appropriate action. This can include using their Self Contained Breathing Apparatus (SCBA) to escape, or to connect to the safe breathable air available from the cascade system.

QBS offers a range of gas detection methods. These include:

  • Personal gas detection. Personal or portable gas detection is used to monitor the atmosphere around personnel and is worn on clothing or on a belt/harness. There are many types available from single gas detectors to 4 or 5 gas detectors. They are usually battery-operated. Personal gas detectors transmit warnings via a series of audible and visible signals such as alarms and flashing lights when dangerous levels of gas vapours are detected.
  • Fixed gas detection. Fixed or ‘hard–wired’ gas detection systems are designed to detect H2S or any other toxic or flammable gasses.
  • Area gas detection. Area gas detection is designed for rapid deployment on the rig-site or offshore installation. These battery powered devices provide a high level audible and visual alarm to alert personnel to the presence of gas. Temporary rental options are available.
  • A range of gas detection supporting accessories.

QBS can design, install or offer rental systems across a range of gas detection methods.


Breathing air compressors can fulfil any requirement from 100lpm to 1000lpm (2.9 to 145 SCFM) charging rate with operating pressures up to 350bar (6000 psi).
