231 Overhead protective structures—particular risk control measures
(1) This clause applies if:(a) construction work is carried out at a place that adjoins a public place or any other property, andbut does not apply to maintenance work on power or telecommunication poles, towers or overhead lines unless a risk assessment identifies that any hazards cannot be controlled by means other than overhead protective structures.(b) that construction work is carried out at a vertical height exceeding 4 metres above the lowest ground level of that public place or other property (unless the ratio of the horizontal distance to the vertical height between the nearest boundary of that public place or other property and where the work is carried out exceeds 2),(2) In any case in which this clause applies, an employer must provide an overhead protective structure that:(a) is of appropriate strength and design having regard to the circumstances of that case, and(b) will catch, deflect or hold any weight and amount of material or objects that might reasonably be expected to fall on it.Maximum penalty: Level 4.

Alternatively, if a bin is used at the discharge end, a fence with a hinged gate that can be securely locked must be provided around the bin at a distance of at least 2 metres from the bin.(3) The employer must ensure that doors and all other openings of the chute (except the discharge end) are closed and securely locked before:(a) any demolished material is removed from any such designated area, or(b) any such bin is replaced.(4) The employer must ensure that notices of the danger from discharged material are prominently placed at the discharge end of the chute and on the access gate of the fence.(5) In this clause, opening, in relation to a chute, means an opening in the side of the chute through which material can be fed into the chute.Maximum penalty: Level 4.
233 Formwork—particular risk control measures
(1) An employer must ensure that formwork complies with AS 3610—1995 Formwork for concrete.(2) An employer must ensure that formwork is designed, constructed and maintained so as to support safely all loads that are to be placed on it.(3) An employer must ensure that, before the concrete pour, formwork is inspected by a qualified engineer and is certified by the qualified engineer as safe for its intended purpose and the loads that will be placed on it.(4) Subclause (3) does not apply if:(a) the deck of the formwork is less than 3 metres above the lowest surrounding ground level, or(b) the area of the formwork deck is less than 16 square metres and is designed to hold not more than 2.5 cubic metres or 6 tonnes of wet concrete (whichever measure is appropriate).Maximum penalty: Level 4.
234 Prevention of structural collapse—particular risk control measures

235 Site security—particular risk control measures
(1) Subject to subclause (2), an employer must ensure that perimeter fencing is provided for all construction sites.(2) Subclause (1) applies with respect to the site of construction of a single dwelling house, duplex or civil engineering project or the site of maintenance work only if a risk assessment identifies the need to isolate particular hazards at the site that cannot be controlled by means other than perimeter fencing.(3) The employer must ensure that perimeter fencing required to be provided by this clause is adequate for the purpose for which it is constructed.(4) An employer must ensure that signs, that are clearly visible from outside the site and on which the name and contact telephone numbers (including an after hours emergency telephone number) of the controller of the site are stated, are placed on each construction site.Maximum penalty: Level 4.
