Lighting Assessments Toolbox Talk

Lighting conditions should be evaluated before work begins and whenever jobsite conditions change. A lighting assessment helps determine whether workers have enough illumination to safely perform their tasks, recognize hazards, operate equipment, and move through the work area. Poor lighting can contribute to slips, trips, falls, struck-by incidents, equipment damage, and reduced work quality. Regular assessments help identify and correct lighting deficiencies before they result in an incident.

This toolbox talk reviews how to perform a basic lighting assessment and the responsibilities of workers and supervisors for maintaining safe visibility throughout the workday.

Why This Matters

• Lighting assessments help identify areas with inadequate visibility.
• Proper illumination allows workers to recognize hazards before incidents occur.
• Good lighting improves work quality, productivity, and accuracy.
• Routine assessments help ensure temporary lighting keeps pace with changing work conditions.
• Correcting lighting deficiencies reduces the risk of injuries and property damage.

Common Hazards

• Insufficient lighting for the task being performed.
• Shadows concealing trip hazards, tools, or equipment.
• Glare from portable lights, headlights, or reflective surfaces.
• Burned-out bulbs or malfunctioning fixtures.
• Changing work locations without relocating temporary lighting.
• Weather conditions reducing outdoor visibility.
• Damaged lighting equipment or electrical cords.
• Poor illumination of walkways, stairs, exits, or equipment operating areas.

Safety Checklist

Before Work Begins

• Assess the work area to ensure adequate lighting for each planned task.
• Inspect permanent and temporary lighting systems for proper operation.
• Evaluate walkways, access routes, stairs, and emergency exits for adequate illumination.
• Identify areas where shadows or glare may interfere with safe work.
• Verify portable lighting is positioned securely and electrical cords are protected from damage.
• Correct or report lighting deficiencies before work starts.

During Work

• Reassess lighting whenever work locations, weather, or jobsite conditions change.
• Adjust lighting to eliminate shadows and improve visibility.
• Replace or report burned-out bulbs and damaged fixtures promptly.
• Monitor lighting around mobile equipment, material storage, and pedestrian routes.
• Ensure task lighting is available for detailed or precision work when needed.
• Stop work if lighting conditions become inadequate for safe operations.

Crew Talking Points

• Is today's work area adequately illuminated for every task?
• Are there any shadows, glare, or dark areas that create hazards?
• Do temporary lights need to be repositioned as work progresses?
• Are walkways, exits, and equipment operating areas clearly visible?
• Who should be notified if lighting conditions become unsafe?
• Speak up immediately if you notice poor visibility or damaged lighting equipment.

Stop Work If

• Lighting is inadequate to safely perform the assigned task.
• Critical hazards cannot be clearly seen.
• Lighting equipment is damaged or creates an electrical hazard.
• Glare or shadows significantly reduce visibility.
• Emergency exits or access routes are not adequately illuminated.
• You cannot safely identify hazards, coworkers, or equipment because of poor lighting.

Final Reminder

Lighting conditions should never be taken for granted. Evaluate work areas before starting the job, adjust lighting as conditions change, correct deficiencies promptly, and stop work whenever visibility is inadequate. A simple lighting assessment can prevent injuries and improve the safety and quality of every task.
