1. is not designed or intended primarily to be occupied by a person; and
2. is, or is designed or intended to be, at normal atmospheric pressure while any person is in the space; and
3. is or is likely to be a risk to health and safety from—
   1. an atmosphere that does not have a safe oxygen level; or
   2. contaminants, including airborne gases, vapours and dusts, that may cause injury from fire or explosion; or
   3. harmful concentrations of any airborne contaminants; or
   4. engulfment;

1. A PCBU must, manage risks to health and safety associated with a confined space at a workplace including risks associated with entering, working in, on or in the vicinity of the confined space (including a risk of a person inadvertently entering the confined space).
2. A PCBU must ensure that a risk assessment is conducted by a competent person.
3. The person must ensure that the risk assessment is recorded in writing.
4. The PCBU must have regard to all relevant matters, including—
   1. whether the work can be carried out without the need to enter the confined space; and
   2. the nature of the confined space; and
   3. if the hazard is associated with the concentration of oxygen or the concentration of airborne contaminants in the confined space—any change that may occur in that concentration; and
   4. the work required to be carried out in the confined space, the range of methods by which the work can be carried out and the proposed method of working; and
   5. the type of emergency procedures, including rescue procedures, required.
5. The PCBU must ensure that a risk assessment is reviewed and as necessary revised by a competent person to reflect any review and revision of control measures.

Confined space entry permit

The PCBU must not direct a worker to enter a confined space to carry out work unless the person has issued a confined space entry permit for the work.

A confined space entry permit must be in writing and completed by a competent person. It must also state the following;

1. the confined space to which the permit relates;
2. the names of persons permitted to enter the space;
3. the period of time during which the work in the space will be carried out;
4. measures to control risk associated with the proposed work in the space; and
5. contain space for an acknowledgement that work in the confined space has been completed and that all persons have left the confined space.

The control measures stated in a confined space permit must be based on a risk assessment and include control measures to be implemented for safe entry and details of the system of work.

The PCBU must ensure that, when the work for which the entry permit was issued is complete all workers leave the confined space; and the acknowledgement is completed by the competent person.
