SG-MP-31-04 Traffic Management Plan

It is the responsibility of all management, supervisory and work group personnel to ensure that hazards and safety issues are resolved as quickly as possible and the workplace is free from hazards.

4.0 PROCEDURE

4.1 Public and Operational Interface

As any Project location’s has interface with the people not involved in the work, extra precautions are required to restrict access into the work area.

This will be achieved by the use of signage and the issuing of information bulletins (on sites) to notify personnel that beyond a designated location is a work area and access is restricted to Project people involved in the work only.

Where appropriate additional warning signs or personnel will be used to control traffic flow.

A dust and water management plan for roads, mining and haulage shall be in place. Consideration shall be given to extreme wet weather and the issue of overwatering roads.

Parking standards shall include requirements for the immobilisation of mobile equipment leg. chocking or spoon drain) and, consideration for breakdown maintenance activities.

Design inspection and maintenance requirements should be in place for all roadways including collision protection of hazardous and critical plant and equipment. Risk assessments should be carried out prior to any changes to traffic movements.

Sitebased traffic management plans will be developed and put in place and not limited to the following:

Setting of appropriate speed limits, and installation and maintenance of road signage;
Right of way rules (including overtaking restrictions);
Access planning in areas identified as hazardous and having significant associated risk;
Systems to control movement of mobile equipment in areas accessible to pedestrians, into and out of workshops, and for controls on pedestrian and light vehicle movement around mobile equipment;
Designated parking areas for heavy vehicles and light vehicles including around maintenance areas;
Systems to control approaching and maintenance crews. Equipment operators or drivers shall be out of the ca bin and dismounted onto ground level when their direct involvement with maintenance or servicing is not required;
Guidelines for abnormal road conditions prior to use (e.g. rain, high winds) giving “go/no go” criteria and stating the responsible person for this decision;
Clear communication procedures for interaction between all vehicles;
Truck loading/unloading protocols to avoid material failing from the vehicle;
Systems to control equipment use within the vicinity of overhead power lines;

4.2 Restricted Area

All areas of an operational plant are to be considered restricted areas unless a relevant access permit/permission is approved.

Normal road and Site specific rules apply. Additional precautions will be taken to ensure visibility and early warning is at a maximum where personnel are working close to roadways. Additional measures may include watering of roads to minimise dust, wearing of high visibility vests and traffic controllers.

Traffic management plans must be approved by the client representative prior to any road works, traffic diversions or disruptions to site traffic.

4.3 Escort Vehicles

Suitably trained and qualified escort personnel and vehicles will be provided for oversize loads in accordance with Main Roads WA regulations.

Truck drivers and escort vehicles must not enter the work site unless they have completed the relevant induction procedures.Light vehicles and mobile plant/equipment must meet the relevant site requirements when entering the project site.

4.4 Maintenance Crews on Infrastructure Roads

The designated speed limit on all access roads must be obeyed, no speed greater than 80km/h will be reached. Infrastructure roads that have conditions where potentially dangerous work is being undertaken (e.g. culverts construction where personnel are close to the access road), shall have a speed restriction of 5 Km and windrows placed along the excavation, signs will also be placed at both ends of the specific work area.

Areas in which infrastructure maintenance crews are working dose to traffic, additional precautions will be taken to keep visibility and early warning at a maximum. This may include minimisation of dust through local watering of dust generating areas, the wearing of high visibility vests and the posting of additional traffic controllers at the extremities of the work environment.

4.5 Working Near Heavy Plant or Equipment

Spotters and other people working near heavy plant or equipment are required to wear high visibility vests or clothing and utilise the correct signage at all times.

4.6 Operational Machinery

In order to delineate the paths of the earth moving machinery, a "Scraper and Mobile Plant Circuit' or similar signs shall be erected 100m prior to the circuits.

To minimise the potential of light vehicles entering the blind spots of heavy vehicles, all other plant and light vehicles and mobile plant are to give way to heavy vehicles operating on any infrastructure road or facility.

Where possible light vehicles will not be allowed on roads used by earthmoving equipment.

4.7 Blind Crests and Corners

To ensure safety of light vehicles and mobile plant traversing over blind crests, widened access roads will be constructed to allow traffic to pass safely in both directions.

The directions of flow shall also be separated by a windrow along the centreline of the crest. This windrow shall be a minimum of 60Omm high. '

Signage indicating keep left shall also be placed at the base of each crest with the intent of directing traffic onto the correct carriageway.

In addition to this, the direction of flow shall be separated by a windrow along the centreline of bends, crest or other locations where there is a risk of light vehicles crossing the centreline and into oncoming traffic.

For areas where the access road cannot be widened in order to separate the flow direction, a "Call up area" will be designated with signage erected to mark the location for call up.

NB. Call up areas can only be used when all vehicles and equipment using that section of road have compatible radios on the same channel.

4.8 Excavations

For excavations on the infrastructure roads over 750mm depth, windrows will be constructed along both edges of the access roads as well as centreline markers to delineate the flow of traffic (similar in nature to. those established in the vicinity of bends and crests etc).

These windrows will be at a suitable height to prevent the largest vehicle driving through. These are of particular importance due to changing nature and conditions of infrastructure roads.

4.9 Road Conditions

Road conditions vary greatly due to environmental factors, the frequency of use, and the load and type of vehicle using the infrastructure roads. Operators must be particularly mindful of the road conditions at all stages of their journey.

Haul roads must be three times wider than the width of the largest vehicle using the road, unless the road is one way.

Roads and tracks shall be regularly inspected using established risk estimation procedures including the variables of time, distance, road surface, load bearing capacity, weather patterns and frequency of use.

This assessment technique shall be used to categorise roads and tracks within the infrastructure system. Road category assessments shall form the statistical basis for a regular information bulletin detailing changes in road categories and scheduled maintenance.

These bulletins shall be distributed to all employee groups for the widest possible dissemination.

4.10 Road Rules

The following are general rules to adhere to whilst travelling through Project sites:

Unloaded light vehicles and mobile plant to give way to loaded plant (water carts carrying water are not considered loaded);
Scrapers to have right of way within the scraper circuit. At the ends of the circuit, other plant and vehicle is to be stationary to allow scrapers and other plant to move on or off the formation;
Light vehicles to give way to all mobile plant on site at all times;
Prior to overtaking slow moving light vehicles and mobile plant (except haul trucks, scrapers and water carts), and where safe to overtake, vehicle operators must make radio contact and receive a reply before overtaking and warn the slow moving vehicle of their intention;
When passing parked or slow moving light vehicles and mobile plant, rollers or graders, radio communication shall be established prior to passing;
Moving Haul trucks and scrapers MUST NOT be overtaken whilst on haul road under any circumstances;
Emergency vehicles and mobile plant, moving haul trucks and scrapers MUST NOT be overtaken under circumstances.

4.11 Signage

All signage must conform to the following requirements, AS 1742.3 and the MIRWA Traffic Management for road works, Code of Practice and must as a minimum:

Give clear direction
Be visible and not obscured.
Be maintained.
Be reviewed regularly for relevance.
Pictograms may be required where tourists' numbers are high.
Flashing lights will be placed to warn drivers of any hazards present at night or in poor visibility.
All side roads to be signed (STOP and NO ENTRY)
No red signage to be erected within 5 metres of any railway.
Search and Rescue & Emergency Access

4.12 Traffic Control

Many methods of traffic control are available and all should be considered when establishing traffic control plans and procedures for sites. Traffic controls can include signage, gates, traffic signals, etc.

4.13 Site Specific Traffic Management Plans

Traffic Management Plans will be in place for all areas of project sites and will detail all traffic management issues, hazards and circuits. The plan will be reviewed and approved by client representative and distributed to all potentially affected parties. The plan will be discussed at the pre shift meetings throughout the site to ensure that ail personnel are aware of the changes.

4.14 Delivery Vehicles Coming to Site

All vehicles delivering materials to site must comply with the Sites vehicles standards and all drivers must be competent in the vehicle operation.

Information packs will be developed for all types of delivery to site and they will include the following:

A plan of the roads leading to the site detailing the correct route to use to get to site;
Contact details for the site and the person they should be asking for;
Details of the clothing and PPE requirements for the site; and
Details what the individual is allowed to do on site and where they can go.

4.15 Journey Management

Where a journey is to be made to a Remote Site, the vehicle operator shall call the arrival point and advise them when they will be arriving on site and when arrived make contact with the person tracking the journey to confirm they have arrived safely.

Contact by radio or similar where available at regular and prearranged times shall be arranged.

In the event of the operator not reporting in to the destination by the nominated time (ETA) plus two hours and no contact able to be established the person tracking the journey or the manager shall:

Immediately confer with the proposed journey log and confirm route, times, personnel, destination and last confirmed check in location/sighting;
Attempt to make radio contact with the vehicle operator. Should the vehicle operator of the missing vehicle fail to be contacted, the Journey & Transport Co-ordinator shall wait for the next scheduled call. If this is not met the following actions is to be taken;
Contact local Emergency Response co-ordinator or crew.
Contact local Police to initiate a co-ordinated SAR. In most cases the Journey & Transport Co-ordinator will have a more detailed knowledge of the area of travel and should liase closely with the relevant emergency services group to assist with SAR operations.
In the event of a search and rescue being conducted, the Journey & Transport Co-ordinator /Exploration Manager, shall initiate the crisis management team and hand over overall responsibility to the Project Manager/Registered Manager.
Unrestricted access will be afforded to emergency personnel, light vehicles and mobile plant and related assets at all times.
Should the emergency alert be raised by radio, all communications should cease and emergency personnel will direct work crews if required by radio.

As a guide the following points should be noted in the event of a breakdown:

Remain calm assistance will arrive shortly.
Try to contact the Journey & Travel Co-ordinator /Exploration Manager and inform them of the situation.
If you cannot contact the Journey & Travel Co-ordinator remain with your vehicle and stay calm.
Stay with the vehicle and use the vehicle for shelter if possible.
Conserve your water and energy. Do not waste it.
Keep out of the sun and rest as much as possible.
If picked up by another vehicle, contact the person tracking the journey and inform them of the situation.
