Gas Testing Atmospheres Training in Perth

MSMWHS217

Gas test atmospheres

Gas test atmospheres training in Perth for workers responsible for atmospheric monitoring before and during confined space entry. MSMWHS217 Gas test atmospheres covers the use of atmospheric monitoring equipment, interpreting test results, and determining safe entry conditions in accordance with WHS requirements. Frequently completed as a combined course with RIIWHS202E Enter and work in confined spaces.

Course Overview

Worker conducts gas test atmospheres training at an open confined space entry point on an Australian industrial site.

MSMWHS217 – Gas Test Atmospheres is the nationally recognised unit covering the skills and knowledge to test atmospheres in confined spaces and other hazardous environments before work begins. Atmospheric hazards — low oxygen, flammable gases, toxic contaminants — often can't be seen or smelled until it's too late, which makes correct testing a critical safety control.


Participants learn to:

  • Select and calibrate gas testing equipment correctly

  • Test for oxygen deficiency, flammable gases, and toxic contaminants

  • Interpret results and determine whether it's safe to proceed

  • Apply correct procedures for ongoing atmospheric monitoring during work


Training is delivered by trainers with genuine industry experience, not just classroom theory. Sessions run at our Bayswater facility or on-site, with on-site delivery available across Perth, the Peel region, and regional WA — letting participants train in the actual environment where they'll be working.

Course Details

Certification

Participants who successfully complete all training and assessment requirements will be issued a Statement of Attainment for MSMWHS217 – Gas Test Atmospheres by Paratus Training (RTO 45274).

Course Outline

  • WHS legislation, Australian Standard AS 2865-2009 Confined Spaces, and workplace procedures for gas testing

  • Common atmospheric hazards — oxygen deficiency, oxygen enrichment, carbon monoxide, hydrogen sulphide, methane, and other flammable and toxic gases

  • Explosive range, upper and lower explosive limits (UEL/LEL)

  • Exposure standards — time-weighted averages (TWA), short-term exposure limits (STEL), and peak limitation values

  • Units of measurement for atmospheric contaminants — mg/m³, ppm, and % v/v

  • Work permit systems and atmospheric testing requirements

  • Determining the type of gas or atmosphere to be tested

  • Selecting and calibrating gas testing equipment in line with procedures

  • Determining the testing regime and sampling pattern required

  • Identifying hazards from possible atmospheric contaminants

  • Implementing hazard control measures and selecting appropriate PPE

  • Using gas testing equipment to test atmospheres — by hand and by lowering on a line

  • Interpreting and reporting gas readings

  • Ongoing atmospheric monitoring during work activities

  • Taking required action when readings are unacceptable

  • Communicating required actions to appropriate personnel

  • Cleaning, inspecting, and fault-finding gas testing equipment

  • Returning equipment to the required location and condition

  • Maintaining records of tests and results in line with workplace procedures

Prerequisites and Entry Requirements

There are no formal prerequisite units required for this course.


All participants must:

  • Have sufficient Language, Literacy and Numeracy (LLN) skills to read and interpret workplace procedures, documentation, and gas readings

  • Hold a valid Unique Student Identifier (USI)

  • Bring a pen

  • Wear appropriate PPE: steel-capped boots, long pants, and a hi-vis long sleeve shirt. If you do not have a hi-vis shirt, Paratus Training can provide a hi-vis vest

Who needs this training?

New to industry

If your role requires you to test atmospheres before or during work — in confined spaces, hot work situations, or any area where hazardous gases may be present — this course gives you the skills and knowledge to conduct testing safely and interpret readings correctly.

Renewal due

There is no legislated expiry date for this unit, however Australian Standard AS 2865-2009 Confined Spaces requires that persons involved in atmospheric testing be reassessed at appropriate intervals. Industry best practice and most employers regard a two-year cycle as the standard. This course gets you back up to date with current equipment, procedures, and exposure standards.

Team training

If your workforce regularly carries out gas testing across confined space, hot work, or field operations, we can come to your site. On-site delivery is available across Western Australia and can be contextualised to the specific equipment and gases relevant to your operations. Contact us to discuss group bookings and scheduling options.
