Final answer:
Using proper lifting techniques and maintaining up-to-date mechanical lifts can help prevent back injuries.
Step-by-step explanation:
Back injuries can occur even when mechanical lifts are being used because lifting objects with the back can cause muscle strain and damage to the discs and vertebrae. When lifting with the back, abnormally large forces are created in the back muscles and spine, which can lead to injury.
To prevent back injuries, it is important to use proper lifting techniques. Instead of using the back, it is recommended to lift objects using the legs. This distributes the weight more evenly and reduces the strain on the back muscles and spine. Additionally, using mechanical lifts that are up-to-date and in good condition can further minimize the risk of injury.
By implementing proper lifting techniques and ensuring that mechanical lifts are in good working condition, the unit manager can address the concern of back injuries occurring despite the use of mechanical lifts. This can help reduce the number of injuries and promote a safer working environment.
