- Equipment Safety Critical Checks
- Any safety critical faults/damage must be tagged out of service and immediately reported to the Supervisor. The equipment must not be used until the issue has been rectified.
- Communication
- Ensure an effective means of two-way communication is established with confined space entrants and a method for raising an emergency.
- Air Quality and Ventilation
- Air quality must be checked prior to entry and periodically (as per Permit), and suitable ventilation must be in place.
- Access Control
- Clearly identify all confined spaces and prevent unauthorised entry, using signage, barriers, covers, or other physical controls.
- Establish Exclusion Zones where confined spaces are not authorised for entry or where atmospheric or engulfment hazards are uncontrolled, physically prevent entry and ensure no persons enter until the space is tested, controlled, and authorised.
- Energy Isolation
- Potentially hazardous sources of energy (solid, liquid, gas) affecting the confined space must be isolated.
- Standby Person
- A standby person must be located outside of the confined space whenever the confined space is occupied, and they must have no other duties during the confined space entry.
