Course Description
The course set including units RIIWHS202E and MSMWHS217 is designed to provide essential skills for working safely in confined spaces and conducting gas testing in hazardous environments. This training is ideal for individuals in industries such as mining, construction, oil and gas, and manufacturing, where confined spaces and hazardous atmospheres pose significant safety risks.
This course set is ideal for workers responsible for confined space entry and atmospheric testing, such as those in mining, construction, and maintenance roles. Upon completion, participants will have the skills to safely enter and work in confined spaces, perform gas testing, and ensure compliance with safety regulations, contributing to a safer workplace in high-risk environments.

Entry Requirements
An individual undertaking this course will need to demonstrate the following to be eligible for entry:
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 sessions and 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).”
