Gas Detector Muti Gas

Gas Detector Course Introduction

The oxygen content of the air we breathe is critical.  Oxygen levels can be depleted or displaced due to the presence of other gases.  The problem is we cannot or may not be able to see or smell the level of oxygen or the presence of gases.  

A gas detector is a life safety device that can measure the level of oxygen in air and/or detect the presence and concentration of gases in air.  Used in a confined space they are normally battery operated portable hand held devices which are-

  1. Single Gas, single sensor designed to detect the available oxygen level (Oxygen sensor) or the presence of a gas ie Methane (Methane sensor)
  2. Multi Gas, multiple sensors designed to detect the available oxygen level(oxygen sensor) or the presence of both flammable and/or toxic gases.  Flammable gases such as Methane (Methane sensor).  Toxic gases such as Hydrogen Sulphide or Carbon Monoxide(either individual H2S sensor and CO sensor or a combined toxic sensor)

Although gas detectors are generally reliable their continued safe and proper function is generally dependent on trained competent users ensuring correct use, maintenance, battery inspection and calibration. This training course is designed to more than adequately provide the level of competence required. 

Gas Detector Course Design.

The Gas Detector Course is intended for anyone required to select, test, operate, use, calibrate, care and maintain battery operated portable multi gas detectors.

This training is delivered as part of Confined Space Training Courses but is offered here as “Stand Alone” training for:

  1. Initial training
  2. Refresher training

Gas Detector Course Content

The course consists of:

Knowledge Element.

  1. Hazards associated with low and high oxygen levels and how/why they occur
  2. Hazards associated with the presence of toxic gases and how/why they occur
  3. Hazards associated with flammable gases and how/why they occur
  4. Potential location of gases and factors that influence the behaviour of a gas.
  5. Factors that affect breathing rate.
  6. Awareness of the legislation, guidance documents, approved codes and manufacturers instructions.
  7. Explanation of the purpose and use of a gas detectors.
  8. Identification and naming the main features of the the gas detector.
  9. Selection criteria, ATEX standards and CE conformity.
  10. Explanation of standard test procedures, competent person and legal requirements of PUWER.
  11. Awareness of calibration procedures, datalogging and software requirements for detectors
  12. Recognition of expiry date of the sensors based on date of manufacture and actual use.
  13. Explanation of fresh air start up test, bump teats and completion of test records.
  14. Detailing the faults, defects or wear and tear that would render a detector unsafe for use.
  15. Recognition of the factors that can influence the sensitivity of a detector.
  16. Detailing other factors that would prevent the use of a detector.
  17. Identification of approved attachments, how to correctly attach and use.
  18. Recognition of audible, visual and vibrating alarms.
  19. Identification and recognition of low alarm, high alarm, STEL, TWA and low battery alarm set points.
  20. Selection and use of other features such as movement alarms
  21. Battery management, care and cleanliness.

Practical Element.

  • Conducting gas tests for vertical and horizontal entry into a confined space.

Gas Detector Course Pre-requisites


Course Notes

  1. It is a legal requirement that all employees required to operate and portable gas detectors receive training.
  2. The training detailed on this page is “specific” gas detector training in that it is specific to the detectors we use.  
  3. Training can be carried out at your premises provided suitable resources are available:
    • Sufficient space to accommodate course numbers
    • Space to use whiteboard, laptop and projector
    • External training area for practical training and exercises.
  4. We use BW Technologies GasAlertMicroClip and GasAlertQuattro detectors for gas detector training.  
  5. We can design and deliver training for other manufacturers equipment.
  6. Specific training can be designed and delivered to meet your needs.
