Course Set - RIIWHS202E, MSMWHS201, MSMPER300, MSMWHS216 & MSMWHS217 Confined space, Operate breathing apparatus, Gas testing atmosphere, Issue work permits and Hazard control

This course set is designed for new and experienced personnel required to work in confined spaces; operate confined space safety equipment including atmospheric gas testing and breathing apparatus; conduct hazard analysis; and issue work permits in the resources and infrastructure industries at an operational levelMany roles require confined space training and this associated skillset including safety, injury prevention and maintenance personnel, engineers, risk managers, mine managers, cable installers and transport personnel and safety observers/ stand-by personnel. 

This course set also applies to individuals who are working alone or as part of a team to conduct a hazard analysis which may be required under a safety case, by organisational procedures or simply as being good practice. It will provide individuals with the skills and knowledge required to conduct a hazard analysis.    

Additionally, this course set applies to individuals who require understanding of the permit system and the limitations of each permit and making decisions regarding the need for and correct use of each permit. This unit includes the issue of any and all permits. Permits are also called ‘clearances’ by some organisations. 

Finally, this course set is for those individuals who may be required to carry out gas testing of an atmosphere prior to entering a specific area or workspace. These working environments may be hazardous, unpredictable, subject to time pressure, chaotic and expose responders to risk, on land or water, by day or night. It covers the skills and knowledge required to test the working atmosphere using electronic test apparatus, to find out if it is safe for the proposed work, interpret readings and take actions based on the interpretation. 

This course set has been designed for individuals who work alone or as part of a team as an operator required to wear breathing apparatus in their work role.  This might be because they are working in a confined space, with hazardous gases/vapours, or in an oxygen deficient atmosphere. It covers the skills and knowledge required to conduct pre-donning checks and tests on breathing apparatus, operate and maintain breathing apparatus and equipment in an irrespirable atmosphere, and conclude operations as defined by the Australian Standard AS/NZS 1715:2009 Selection, use and maintenance of respiratory protective equipment. 

Units Delivered

The following units will be included in your certificate:

RIIWHS202E - Enter and work in confined spaces
MSMWHS216 - Operate breathing apparatus
MSMWHS217 - Gas test atmospheres
MSMWHS201 - Conduct hazard analysis
MSMPER300 - Issue work permits

Course Delivery

This course can be delivered/assessed in the workplace or at facility organised by the training provider.

Course Durations

Course durations can vary for multiple reasons, so the durations below are the minimum possible amount.

Refresher Face to Face contact time of at least 10 Hours
Face-to-Face Face to Face contact time of at least 16 Hours

An individual undertaking this course will need to demonstrate the following to be eligible for entry: 

  • Participants must be clean shaven to attend the course. The unit of competency states that participants “Don the apparatus in accordance with workplace procedures and the manufacturer’s specifications.” The manufacturer’s specifications state: “The sealing line between head and facepiece must be free of hair and foreign substances which could cause leakages”

  • To successfully complete MSMPER300 Issue work permits, a student must hold the pre-requisite unit MSMWHS201 Conduct hazard analysis.  

  • Psychological* and physical capability to be able to meet the demands of the practical demonstrations for this course, such as the undertaking of the requirements to safely enter, work in and exit a confined space wearing appropriate PPE.This may involve climbing up, down, through or under structures or confined spaces, being temporarily suspended, wearing harnesses and other relevant PPE, dragging and lifting in confined and restricted environments in dark, low light or smoke-filled areas. 

  • Protective footwear/safety shoes and comfortable/practical clothing must be provided by the student and worn during the practical sessionsand assessment 

  • Language, literacy and numeracy requirements - students must be able to read and correctly interpret required documentation relevant to the confined space entry, speak clearly and unambiguously in English, explain, describe and verify sometimes complex needs and issues and understand the permit requirements. Writing is required to the level of completing workplace forms and producing any required reports. Numeracy is required to the level of being able to correctly differentiate between high and low pressures and temperatures, voltages or masses and interpret gas test/monitoring results. 


*Safe Work Australia notes “Working in a confined space may impose physiological and psychological demands over and above those encountered in a normal working environment. Consideration should be given to a worker’s: 

  • physical ability; 

  • ability to work in a restrictive space (for example claustrophobia) and ability to wear the PPE required to do the work (for example respirators).”
