There are a number of issues you may not be aware of that will affect your safety.
If you have long hair, it should be tied back, put in a hairnet or cap to keep it away from rotating machinery. Loose clothing or jewelry could also get caught in machinery, so remove anything that could get caught and wear coveralls or an approved work uniform.
Depending on the equipment you’re using, you may need to wear protective gloves, footwear, “eye” or ear protection, full-face protection or even a hard-hat. And wear a respirator to protect your lungs while working with caustic materials or gases.
Prevent back injuries when lifting heavy objects. Crouch with your legs slightly apart, stand close to the object and position yourself so that the center of gravity is between your feet. Keep your back straight, and use your legs to lift the object.
