Being young and strong, they sometimes carry more weight than they should. Make sure apprentices are protected against back injuries, so they don't end up with back problems and have to leave the trades. Work with your employer to decide how the work can be changed to protect you and your co-workers from back injuries. Build back-safety into any training. Fewer injuries mean better productivity and lower costs.
Some companies have workers wear back belts.
Back belts may help someone recovering from a back injury. But there is not much evidence they can prevent injuries. Back belts should never be used instead of making work safer.
