Discuss this course →English master · Awareness · v2.0
PERFORMANCE OBJECTIVES

What learners will practise.

  • Recognise potential confined-space hazards and the need for formal evaluation.
  • Explain the controls and roles required before authorised entry.
  • Respond to an alarm or casualty without attempting an unplanned entry rescue.
  • Apply the course decisions to a worked case and justify a response to the capstone.
  • Record control evidence, responsible roles and stop/escalation conditions in the workplace worksheet.

A SAMPLE OF THE APPROACH

Start with understanding.

Confined-space definitions differ between legal systems. Do not classify a space by size alone. Tanks, pits and other enclosed or partly enclosed areas may have dangerous atmospheres, engulfment or other serious hazards. A competent evaluation of the space and planned work determines the required controls.

Then make a decision.

A worker collapses inside a tank. A colleague at the opening can see them and wants to climb in immediately. The atmosphere status is unknown and the planned rescue team has not arrived.

Discuss: What are the facts, what could go wrong, and what must be verified before proceeding?

Make it specific to your workplace.

  • Applicable definition, classification and entry permit system
  • Competent testing, isolation and ventilation requirements
  • Entrant, attendant, supervisor and rescue arrangements

Before deployment, confirm these details with the client’s responsible technical reviewer. The course is a starting point for awareness learning, not a replacement for approved work procedures.
