7 Task # Job steps Hazards / Risks Risk Class Controls Residu al Risk Responsible 1 Site planning and setup TRAFFIC Workers being hit by passing vehicles Vehicle collisions Pedestrian hit by passing vehicle Movement of heavy materials and equipment Slips / trips and falls Working in Hot and Cold climates 1. Park vehicle in a safe location; Use of side roads with lower traffic volume is preferable, DONOT block driveways or access ways. All new workers and visitors to site must be inducted to and sign onto SWMA. 2. TELSTRA Using Telstra s Impact Worksites Traffic Management Plans ( ), select the most appropriate Traffic Situation. Delineate the worksite using guards, bollards, parawebbing, cones, bollards etc. 3. NBN Co. Using NBN Co Traffic Guidance Scheme cards (TGS), select the most appropriate Traffic Situation. Delineate the worksite using guards, bollards, parawebbing, cones, bollards etc. Open pits and manholes must not create a trip or fall hazard, ensure delineation and signage. Scenario 1 & 2 are for short term parking only and all scenarios above these require a competent qualified controller to implement (Minimum Yellow Card) 4. Where a Traffic Situation cannot be matched to the worksite, contact your Supervisor for assistance as professional traffic management may be required. Crash barriers will be required if working within 1.2 meters of a road edge and traffic will need to be reduced to 40 km/h or less. 5. visibility Orange Long sleeve, long leg work wear and safety footwear must be worn when working on the road side.

8 IMPACTS ON RESIDENTS, OTHER AUTHORITIES AND BUSINESSES 1. Ensure vehicles, Plant, equipment and materials are stored and located so as not to interfere with residents, business owners and other construction workers 1 Site planning and setup Aggressive Customers / members of public Block access and egress Dog bites Spiders and other dangerous fauna Slips / trips and fall 2. Prior to entering resident s property, conduct a visual inspection of the customer premises to identify potential hazards such as dogs, waste material and debris. 3. Where an unrestrained dog is identified, DO NOT ENTER the premises until contact with the owner has been achieved (e.g. via phone or gate intercom) and the dog has been restrained/secured or isolated. before work commences Working in construction zones Working in landfill and contaminated land areas 4. If a resident or business owner becomes agitated or aggressive, do not confront or provoke. Seek advice from your Supervisor to determine the most appropriate course of action. Where the customer is threatening or becoming physically aggressive, remove yourself from the site immediately. 5. When working in construction zones ensure that an appropriate Vehicle Movement Plan (VMP) is incorporated to ensure all workers are aware of plant, people and vehicle movements. Positive communications must be maintained and a spotter or third party traffic control may be required to direct traffic. All workers onsite need to be informed of construction activities and possible risks that may impact on them. 6. Workers are not permitted to work in contaminated soil areas without the permission of the land owner and all suitable precautions being undertaken.
