I wasn't able to find specific documentation on developing a Job Safety Analysis (JSA) for safely changing a vehicle tire in our current safety knowledge base, but here are industry-standard safety guidelines:

A Job Safety Analysis (JSA) for changing a vehicle tire involves a systematic approach to identify potential hazards, assess risks, and implement control measures to prevent injuries and ensure regulatory compliance. Here's a general outline:

1. Job Step: List each step of the tire changing process (e.g., preparing the vehicle, loosening lug nuts, jacking up the vehicle, removing the tire, mounting the new tire, tightening lug nuts, lowering the vehicle). 2. Hazards: Identify potential hazards associated with each step (e.g., vehicle rolling, dropping the vehicle off the jack, musculoskeletal injuries, flying debris, pinch points). 3. Risk Assessment: Evaluate the level of risk for each hazard (e.g., high, medium, low) based on the likelihood and severity of potential injuries. 4. Control Measures: Implement specific actions to eliminate or minimize each hazard (e.g., using wheel chocks, using a jack stand, wearing safety glasses and gloves, using proper lifting techniques, following manufacturer's torque specifications).

Detailed JSA Steps:

• Preparation:
• Hazard: Vehicle rolling.
• Risk: Serious injury or death.
• Control: Park on a level surface, engage the parking brake, and use wheel chocks.
• Loosening Lug Nuts:
• Hazard: Stripped or damaged lug nuts, hand injury.
• Risk: Minor to moderate injury.
• Control: Use the correct size wrench, apply steady pressure, and wear gloves.
• Jacking Up the Vehicle:
• Hazard: Vehicle slipping or falling off the jack.
• Risk: Serious injury or death.
• Control: Place the jack on a solid, level surface at the manufacturer's recommended jacking points. Use a jack stand for added support.
• Removing the Tire:
• Hazard: Heavy lifting, dropping the tire.
• Risk: Musculoskeletal injuries (back strain, etc.).
• Control: Use proper lifting techniques (bend knees, keep back straight), and get assistance if needed.
• Mounting the New Tire:
• Hazard: Pinch points, dropping the tire.
• Risk: Hand or foot injuries.
• Control: Wear gloves, use proper alignment techniques, and get assistance if needed.
• Tightening Lug Nuts:
• Hazard: Over- or under-tightening lug nuts.
• Risk: Wheel detachment, damaged wheel studs.
• Control: Use a torque wrench to tighten lug nuts to the manufacturer's specified torque. Tighten in a star pattern.
• Lowering the Vehicle:
• Hazard: Vehicle falling off the jack.
• Risk: Serious injury or death.
• Control: Ensure the area is clear, lower the vehicle slowly and steadily, and remove the jack carefully.
• Final Check:
• Hazard: Loose lug nuts.
• Risk: Wheel detachment.
• Control: Re-torque lug nuts after driving a short distance (e.g., 50-100 miles).

When working with axles, it's important to adhere to specific torque specifications. Axle torque specifications are available, and it is important to use the correct values for the specific equipment and bolt type being worked on. Note that 1 Nm = 0.7376 ft-lb.

Additionally, daily inspections should include checking the wheel/tire assembly.
