Material-storage hazards are sources of poten- tial injury that come from the improper storage of files, books, office equipment, or other items. A clut- tered workplace is an unsafe workplace. Material stacked too high can fall on employees. Paper and files stored on the floor or in a hall are a fire risk. To prevent material-storage injuries, take the following precautions: • do not stack boxes or papers on top of tall cabinets • store heavier objects on lower shelves • keep aisles and hallways clear Maintaining a safe workplace is the joint respon- sibility of the employer and employee. The employer makes sure the facility and working conditions are such that accidents are unlikely to occur, and the employee uses common sense and care while at the office. Keys to maintaining a safe working environment include reading and understanding equipment safety manu- als, following safety instructions, and abiding by safety requirements.
