Confined space are identified by a competent person, appropriate signage applied and there is a register (or similar) which identifies confined spaces.
Critical Risk Ref. 3.1
Work planning processes considered whether the requirements to enter confined space can be eliminated.
Critical Risk Ref. 3.2
Workers involved in confined space work have attained competencies in accordance with the Australian training framework (or international equivalent) for; - working in confined space - atmospheric monitoring of confined space - supervision of confined space work
Critical Risk Ref. 3.3
Prior to entry a confined space permit is completed and authorised by a competent worker. The permit includes an assessment of the hazards and specific controls required to manage hazards, tracking of persons entering the confined space, rescue plan requirements, emergency communications/contacts.
Critical Risk Ref. 3.5
Prior to entry, testing of atmospheric conditions by a competent person utilising calibrated equipment is required. Atmospheric testing will include: oxygen, H2S, CO, LEL. Where their is a risk for atmospheric hazards, monitoring of that atmosphere will be continuous.
Critical Risk Ref. 3.6 & 3.9
A competent confined space sentry/standby percent shall be located outside of a confined space at all times when the confined space is occupied. The sentry shall be trained in atmospheric monitoring and will be supplied with means of communication with entrants.
Critical Risk Ref. 3.8
Any systems likely to influence the atmospheric or physical status of the confined space are identified, purged and/or confirmed isolated before entry into the confined space.
Critical Risk Ref. 3.4
Sentries have an effective means of two-way communication with confined space entrants and a method of activating an emergency response.
Critical Risk Ref. 3.10
Confined space entrants wear a harness where required to facilitate rescue in the event of a emergency.
Critical Risk Ref. 3.7
Confined space work is controlled as per requirements above. Where rescue equipment has been established it is appropriate and would be effective for rescue if deployed.
Critical Risk Ref. 3.5
Conduct interview with supervisor and relevant workers are aware of the procedural requirement for planning, monitoring and undertaking work in confined space.
