　　Be Wary While Lifting

　　Lifting even small loads (stacks of files, computer paper, a computer monitor, etc.) can lead to injury if done improperly. Your back, neck and shoulders are all susceptible to this type of injury. Before you decide to lift anything, be sure it is not too heavy for you (if it is, ask a co-worker or supervisor to help).
