loosen wheel nuts "what is the risk asoisiated with that and what are the cntorl measures we apply"

The risks associated with loosening wheel nuts include:

1. Injury: If not done correctly, the wheel could potentially fall off and cause injury.

2. Damage to the vehicle: If the wheel nuts are not properly loosened, it could lead to damage to the wheel or the vehicle itself.

3. Stripped threads: If too much force is used, the threads on the wheel nuts could be stripped, making it difficult to remove or replace the nuts.

Control measures to mitigate these risks include:

1. Use the correct tools: Always use a torque wrench or wheel brace that fits the wheel nuts correctly. This will help prevent damage to the nuts and ensure they are loosened correctly.

2. Follow proper procedure: Always loosen the wheel nuts in a star pattern, not in a circular pattern. This helps to ensure the wheel is removed evenly and reduces the risk of damage.

3. Safety gear: Always wear appropriate safety gear, such as gloves and safety glasses, to protect yourself from potential injury.

4. Training: Ensure that anyone who is loosening wheel nuts is properly trained in how to do so safely and correctly.

5. Regular maintenance: Regularly inspect and maintain the wheel nuts and threads to ensure they are in good condition and safe to use.
