South Australian Consolidated Regulations (1) If a
risk assessment (or a review of a risk assessment) indicates a risk to health
or safety, an employer must ensure that no person enters a confined space
unless a person or persons are on stand-by outside the confined space to
render assistance in the event of an emergency.
(2) An employer must
provide appropriate arrangements for the effective rescue of a person from a
confined space in the event of an emergency, including—
(a)
openings for entry and exit to the confined space of adequate size to permit
rescue of any person who may enter the confined space; and
(b)
procedures to prevent obstruction of the openings by fittings or equipment
which could impede rescue,
or, where compliance with paragraphs (a) and (b) is not reasonably
practicable, by the provision of a suitable alternative means of rescue.
