This guideline describes the loading of aggregate into tandem or semi-trailer trucks, weighing of the load at a scale and delivery of the load to the proper location on the road.
- Crushing, muscle pull/strain, pinch points, slip, trip and fall.
- Equipment accidents/incidents, struck-by.
- Visibility, weather, dust.
- Pre-Job Planning
1.1 Ensure that workers are properly trained and competently supervised.
1.2 Ensure that the Truck drivers have received the Trucker orientation and are familiar with the “Road Checker Orientation” documents.
1.3 Identify any special hazards and controls.
1.4 Equipment operators must be familiar with and adhere to all Traffic Accommodation, Work Zone Traffic Control Plans and Emergency Plans.
1.5 Ensure that you have sufficient resources (labour, personal protective equipment (PPE), equipment and materials) to carry out the task safely.
1.6 Knowledge of material weights, gross vehicle weight (GVW), road restrictions and road conditions.
- Circle Check
2.1 Complete circle check and documentation daily.
2.2 Each operator must conduct a circle check on equipment being operated to detect equipment deficiencies and ensure that safety related defects and other necessary repairs or deficiencies are corrected prior to operating the unit.
2.3 The operator should only perform repairs or adjustments that they can perform competently and have other repairs performed by a qualified/competent person.
2.4 Ensure safety devices are in good working order.
2.5 Ensure all horns, lights and back up alarms are in good working condition.
2.6 When repairs or maintenance are performed on site, you must ensure that the operator’s controls are made inoperable so that the equipment cannot be moved by another worker while repairs are being made. (i.e. Lock Out / Tag Out system).
2.7 The supervisor shall be responsible to ensure daily pre-shift equipment checks are performed and verify that any problems are corrected.
2.7.1 Because equipment may be inspected and operated by various people, the supervisor must be responsible for ensuring that inspections are performed daily, that necessary repairs are made, that scheduled maintenance is performed, and that records of all inspections and repairs are maintained.
- Truck Operation
3.1 Enter and exit cab by using the three point contact method.
3.2 Seat belts are required at all times when truck is in use.
3.3 All drivers must have proper licenses for units they are operating.
3.4 Truck speed should be adjusted for load, weather and road conditions.
3.5 Extra caution is required when moving through all urban areas.
3.6 Activate appropriate warning lights if vehicle is slowing down, stopped on a highway or haul road, or when operating in a work zone.
3.7 Whenever the operator leaves the cab of his truck all personal protective equipment (PPE) must be worn.
- Loading Operation
4.1 When loading material, use the drive thru process to drive under loading conveyors.
4.2 If the unit has to be backed in for loading, refer to Safe Operating Guideline for Backing up.
4.3 Load box in a manner that will distribute the weight evenly.
4.4 Make sure all loose material from the exterior of the truck box is removed. If the material in the box might blow off, load should be covered with a tarp.
- Weighing Operation at the Scale Site
5.1 Weigh scale should be placed with consideration of work activities and traffic flow.
5.2 Never back on or off a scale. There is a greater risk of a truck going over the edge causing injury, damage and delays.
5.3 The approach ramps to the scale should be long enough to ensure the longest truck can approach the scale on the level so operator can sight down the trailer as they drive onto scale.
5.4 When a low profile scale is used the approach ramps will be lower and shorter.
5.5 Be aware of the width of the scale.
5.6 Ensure area is clear before approaching and going onto scale.
5.7 Drive onto scale in the proper direction: the scale-house should always be on the driver’s side of the unit.
5.8 Drive onto scale at a low speed.
5.9 Do not make any sudden brake applications.
5.10 If operator has to exit and enter the cab, use the three point contact method for better footing.
5.11 Be aware of the approved overweight dumping procedure and the location of the area to dump the excess load. Never back up off the scale always proceed forward.
5.12 After weighing has been completed, proceed forward off the scale at a low rate of speed.
- Hauling Operation
6.1 When driving to the work site, the operator should travel at speeds appropriate for the road and weather conditions.
6.2 When approaching the work zone, if there is a flagging station with traffic being stopped in a queue the operator must stop at the end of the queue. Jumping the queue may only be done if in accordance with Section 7 of this guideline.
6.3 When in the traffic queue, don’t visit in groups around trucks or equipment.
6.4 Proceed with the rest of the traffic only when signaled by the flag person to do so.
6.5 Be sure to activate all rotating lights when in the work zone.
6.6 When traveling on the wrong side of the road, be aware of the increased risk of traffic and make sure to check for traffic before changing lanes.
- Jumping the Queue at the Flagstation
7.1 Under certain circumstances, the Project Manager and the Construction Supervisor may agree to allow aggregate delivery trucks to “Jump the Queue” where traffic is being stopped by a flagperson.
7.2 Verbal agreement is not sufficient. Verbal instructions to the flaggers are not sufficient. There must be a written, documented Traffic Control Plan agreed to prior to any truck “Jumping the Queue”.
7.3 Where one lane of traffic through the work area only is available, the flagger must be able to see the complete work area where the truck will be driving after jumping the queue, and ensure that it is free of traffic. Radio communication alone will be insufficient.
7.4 Where two lanes of traffic through the majority of the work area is available and the truck operator can stop where required to allow oncoming queues of traffic to pass, radio communication of ability to proceed may be allowed.
7.5 The flagger may signal a truck operator in the queue to proceed while at the same time holding the rest of the traffic queue in place.
7.5.1 If the truck is too far back in the queue that other traffic will mistake the flaggers intentions, the flagger shall not signal the truck to proceed.
7.5.2 The signal may consist of:
22.214.171.124 Radio communication between the flagger and the trucker.
126.96.36.199 While facing the queue of traffic, pointing at the truck driver, rotating one hand vertically then pointing to the free lane, while holding the sign paddle showing the Stop sign.
7.5.3 Before the truck leaves the queue, the rotating lights must be turned on.
7.5.4 As the truck pulls out in to the free lane, the flagger must watch other traffic to see that they do not pull out and follow the truck. If other traffic does pull out to follow the truck, the flagger must control them with hand signals, flag sign and positive direction.
7.6 If an operator jumps the queue prior to the development of the agreed upon Traffic Control Plan, or fails to follow the Traffic Control Plan and/or the flagger’s signals, the operator will be removed from the project.
- Dumping Operation
8.1 As the operator approaches the dumping location, make sure that all proper traffic procedures are used to avoid accidents.
8.2 Drive to the end of the windrow and proceed to front of the line of trucks waiting to dump.
8.3 Back up when indicated by the Road Checker.
8.4 Obey all signals given by the Checker.
8.5 Truck and trailer should always be in a straight line and level on firm ground before dumping. Additional care should be taken in windy conditions or on superelevation before dumping.
8.6 Give the weight ticket to the Checker. Ensure your spreader chains are properly set for the commodity you are dumping.
8.7 Always be aware of your surroundings. If unsure ask Checker if there are any overhead power lines. Checker should remind the operators if there are any overhead obstructions.
8.8 For dumping of the load referrer to “Road Checker Orientation” documents.
8.9 If there are overhead power lines, follow the Safe Operating Guideline for Work around Overhead Power Lines.
8.10 If dumping two windrows that are side by side, then proper spacing between the ends of each windrow is important – stagger them at least 3 to 5 truck lengths. Never have two trucks dumping beside one another at the same time.
8.11 At any time during dumping operations, if the operator loses site of the Checker, stop immediately.
8.12 Drive to the designated turn around site as per the Traffic Control Plan. Do not back up to turn around at the dumping area. Backing up past the Checker is immediate removal from the Project.
