Task: Changing a tire for a client
Steps:
-
Assessment and Preparation:
- Assess the vehicle's surroundings for potential hazards such as traffic, uneven ground, or nearby obstacles.
- Park the vehicle on a flat, stable surface away from traffic if possible.
- Engage the parking brake and turn off the engine.
-
Gathering Tools and Equipment:
- Gather all necessary tools and equipment: spare tire, jack, lug wrench, and any additional safety equipment such as reflective vests or warning triangles.
-
Lifting the Vehicle:
- Position the jack under the vehicle's frame or designated lifting point, as per the vehicle's manual.
- Ensure the jack is stable and secure on a flat surface.
- Use caution when lifting the vehicle to prevent strain or injury to your back.
-
Loosening Lug Nuts:
- Use the lug wrench to loosen the lug nuts on the flat tire, but do not remove them completely yet.
- Apply steady pressure while loosening to avoid slipping or sudden movements.
-
Removing the Flat Tire:
- Once lug nuts are loosened, carefully remove the flat tire from the hub.
- Handle the tire with care to avoid strain or injury, especially if it's heavy or awkwardly positioned.
-
Mounting the Spare Tire:
- Align the spare tire with the wheel studs on the hub.
- Lift the spare tire onto the hub, ensuring it is properly seated.
-
Securing Lug Nuts:
- Hand-tighten the lug nuts onto the wheel studs to secure the spare tire in place.
- Use the lug wrench to tighten the lug nuts in a star pattern to ensure even tightening and prevent warping of the wheel.
-
Lowering the Vehicle:
- Carefully lower the vehicle using the jack, ensuring it is lowered evenly and securely onto the ground.
- Double-check that all lug nuts are securely tightened.
-
Stowing Equipment:
- Properly stow all tools and equipment, ensuring they are secured in the vehicle.
-
Final Inspection:
- Conduct a final inspection of the vehicle to ensure the spare tire is properly installed and all tools are accounted for.
- Test drive the vehicle at low speeds to ensure the spare tire is functioning correctly.
Hazards:
- Crushing or Pinching Injuries: Risk of injury when lifting the vehicle with the jack or handling heavy tires.
- Slip, Trip, and Fall Hazards: Uneven ground, debris, or slippery surfaces can lead to slips, trips, or falls.
- Traffic Hazards: Working near roadways poses a risk of being struck by passing vehicles.
- Musculoskeletal Injuries: Strain or injury from awkward postures, repetitive motions, or lifting heavy objects.
- Tool and Equipment Hazards: Risk of cuts, bruises, or other injuries when using tools such as lug wrenches.
Control Measures:
- Use proper lifting techniques and mechanical aids when lifting heavy objects.
- Wear appropriate personal protective equipment (PPE) such as gloves and safety boots.
- Maintain awareness of surroundings and be cautious of traffic when working roadside.
- Follow manufacturer instructions for the safe use of tools and equipment.
- Take regular breaks to prevent fatigue and reduce the risk of musculoskeletal injuries.
Responsible Person: The person performing the tire change is responsible for following this JSA, assessing the environment for hazards, and taking appropriate safety precautions throughout the task.
Review and Revision: This JSA should be periodically reviewed and revised as needed to incorporate any changes in procedures, equipment, or regulations, and to address any new hazards that may arise.
