3. Ergonomics Definition –the science of adapting workstations, tools, equipment and job practices to be compatible with the individual worker and thus reduce the risk of injury due to risk factors Definition –the science of adapting workstations, tools, equipment and job practices to be compatible with the individual worker and thus reduce the risk of injury due to risk factors

4. Ergonomics Alternate work activities to prevent physical and mental fatigue. –If possible, change the order of your work to provide some variety. Take frequent breaks. –Every 15 minutes, look away from the screen to give your eyes a break. –At least once per hour, get out of your chair and move around. Every two hours, take at least a 15 minute break. Alternate work activities to prevent physical and mental fatigue. –If possible, change the order of your work to provide some variety.

14. Office Safety Chairs on castors must have 5 legs. If your desk is too high, compensate by raising the seat height of your chair Never stand on the chair to reach anything, particular if the chair has wheels or is of the swivel kind. Never use your chair to roll to another location. Do not spin around in your chair. Push your chair in when you get up. Chairs on castors must have 5 legs.
