Glare Reduction Toolbox Talk

Glare occurs when excessive or poorly directed light interferes with a worker's ability to see clearly. It can come from sunlight, work lights, vehicle headlights, reflective surfaces, or improperly positioned lighting fixtures. Glare reduces visibility, increases eye strain and fatigue, and can contribute to slips, trips, falls, struck-by incidents, and operating errors. Managing glare is an important part of maintaining a safe work environment.

This toolbox talk reviews common sources of glare and the steps workers can take to improve visibility while reducing eye strain and safety risks.

Why This Matters

• Reducing glare improves visibility and hazard recognition.
• Proper lighting helps prevent slips, trips, falls, and struck-by incidents.
• Managing glare reduces eye fatigue and improves worker comfort.
• Equipment operators can better identify people, obstacles, and travel paths.
• Balanced lighting improves work quality and overall jobsite safety.

Common Hazards

• Sunlight shining directly into workers' or operators' eyes.
• Portable work lights aimed toward personnel.
• Vehicle headlights creating temporary blindness.
• Reflective metal, glass, water, or polished surfaces.
• Lighting fixtures positioned too high or too low.
• Moving between bright and dark work areas without allowing eyes to adjust.
• Dirty light lenses causing scattered light.
• Poorly maintained lighting creating uneven illumination.

Safety Checklist

Before Work Begins

• Inspect the work area for potential glare sources.
• Position temporary lighting to illuminate the work without shining directly into workers' eyes.
• Adjust lighting angles to reduce reflections from equipment and work surfaces.
• Clean lighting fixtures and lenses to improve light distribution.
• Consider the position of the sun when planning outdoor work.
• Use task lighting where focused illumination is needed instead of increasing overall brightness.

During Work

• Reposition portable lights if glare develops as work progresses.
• Reduce speed when operating vehicles or equipment if glare affects visibility.
• Allow your eyes time to adjust when moving between areas with significantly different lighting levels.
• Use appropriate eye protection with tinted or shaded lenses only when suitable for the task and lighting conditions.
• Report lighting arrangements that create unsafe visibility conditions.
• Stop and correct lighting issues before continuing work if glare prevents safe operation.

Crew Talking Points

• What sources of glare are present in today's work area?
• Can portable lighting be repositioned to improve visibility?
• How does glare affect equipment operators and pedestrians?
• What should you do if sunlight or work lights prevent you from seeing clearly?
• Which tasks require additional lighting without increasing glare?
• Speak up immediately if glare makes it difficult to safely perform your work.

Stop Work If

• Glare prevents you from clearly seeing hazards or coworkers.
• Vehicle or equipment operators cannot safely see their travel path.
• Lighting cannot be adjusted to provide safe visibility.
• Reflective surfaces create unsafe working conditions.
• Eye strain or reduced visibility compromises safe work.
• You cannot safely perform the task because of excessive glare.

Final Reminder

Too much light can be just as dangerous as too little. Position lighting carefully, minimize glare from sunlight and artificial sources, keep fixtures clean, and adjust work practices whenever visibility is affected. If glare prevents you from working safely, stop and correct the lighting before continuing.
