Back Safety Training

Explanation
Using legs to lift a load is least likely to lead to back injuries because it is the correct technique for lifting heavy objects. By using the legs to generate the lifting force, the back is kept straight and the load is distributed evenly throughout the body. This reduces the strain on the back muscles and minimizes the risk of injury.

Explanation
All of the listed factors - stress, overweight/obesity, poor posture, and poor physical condition - can contribute to back injury. Stress can cause muscle tension, leading to back pain. Excess weight puts additional strain on the back, increasing the risk of injury. Poor posture and weak muscles can lead to improper alignment and lack of support for the spine, making it more susceptible to injury. Therefore, all of these factors can play a role in causing or exacerbating back injuries.

Explanation
The correct answer is to lift slowly with legs, keeping the back straight. This technique is recommended to prevent strain and injury to the back. Lifting slowly allows for better control and stability, while using the legs instead of the back muscles helps distribute the weight evenly and reduces the risk of back strain. Keeping the back straight further supports proper alignment and reduces the strain on the spine.

Explanation
Improper lifting is the most common cause of back injuries at work. When individuals do not use proper lifting techniques, such as bending at the knees and using their leg muscles instead of their back muscles, it puts excessive strain on the back. This can lead to muscle strains, sprains, and even more serious injuries like herniated discs. Therefore, it is important for individuals to receive proper training on lifting techniques and to use equipment like back braces or lifting aids when necessary to prevent these injuries.

Explanation
When carrying material, it should be held low and close to the body to maintain balance and minimize strain on the muscles and joints. This position allows for better control and reduces the risk of dropping or losing control of the material. Holding it at arms length can cause fatigue and increase the chances of accidents. Holding it overhead can strain the shoulders and upper body, leading to potential injuries. Therefore, the best and safest way to carry material is to keep it low and close to the body.
