The hazard
A tired worker reacts slower, misses hazards and makes more mistakes, often without noticing. Fatigue builds up from long shifts, night work, heat, hard physical work, stress and too many short nights in a row. Around equipment, heights or traffic, one slow reaction can be enough to get someone hurt.
The action
If you are too tired to work safely, tell your supervisor before you start a hazardous task, not after something goes wrong. If a coworker seems unsafe, say something to them and let the supervisor know. Stress and worry can also wear you down and cost you sleep, so talk to someone you trust or use your employee assistance program if your company has one.
