SP08 Barricades Falling Object and Public Protection


The erection of barricading, falling object protection and specific site controls are critical to ensure that members of the public may not be injured by the undertakings of Silverback and the activities of its subcontractors. The implementation of such controls may also be critical to isolate and exclude specific high-risk work areas within a site so that groups of workers on site may not be injured by the activities of others.

This procedure addresses a number of work situations where standard control mechanisms may be implemented to protect workers and the public. It must be stated however, that the requirements stated in this procedure must be done so in conjunction with a risk assessment, specific to each high-risk work activity or potential public exposure.

Every operation performed by Silverback personnel and subcontractors may involve potentially different public safety issues depending on.

  • the layout and location of the work area,
  • the number of people who have access to or around the work area,
  • the methods of public access and egress around the work area (roadways, footpaths, etc)
  • the time-of-day that the work is performed (early morning, peak hour, night) and ultimately,
  • the work methods employed (EWP use, safety nets, gantries, scaffolding, etc)


Silverback and subcontracted personnel are to comply with the relevant provisions of the following procedural requirements and references. The typical hazards addressed by this procedure include:

Hazards Risk (Potential)
  • Falling objects
  • Flying particles/materials
  • Contact with moving plant/machinery


Where public access or interaction is foreseeable on or around site, appropriate measures are to be taken to warn the public of the work activity and associated hazards, exclude the public, isolate equipment and provide overhead protection against falling objects in accordance with the following.

  1. Warning/hazard signs are to be used to clearly identify areas on and around the perimeter of sites as being a place of work. This includes signage to adequately indicate to the public: a. the nature of the workplace, b. that unauthorised entry to the workplace is not allowed, and c. that they are not to use the adjoining area in stated circumstances, ie “Do not proceed if light is flashing. Load is being lifted onto site”.
  2. Public areas are to be kept clear of any debris, trip or slip hazards and protected from any projectiles, dust etc that may be released as a product of work undertaken.
  3. The risk of death or injury to members of the public that may result from unauthorised access or objects falling or otherwise hitting a member of the public in an adjoining area must be determined and controls put in place before work starts. Controls could include signage, barricades, boarding etc. with details recorded in the Construction Workplace Plan.
  4. Barricades are to be used on site to create temporary exclusion zones where work is being undertaken above, or restricted access to hazards such as trenches is required within the boundary of the site.
