Temporary Lighting Safety Toolbox Talk

Temporary lighting is commonly used on construction sites, maintenance projects, and other work areas where permanent lighting is unavailable or insufficient. While it improves visibility, temporary lighting also introduces electrical hazards, trip hazards, and equipment damage risks if it is not properly installed, maintained, and used. Safe temporary lighting provides adequate illumination without creating additional workplace hazards.

This toolbox talk reviews the safe use of temporary lighting and the precautions workers should take before and during its use.

Why This Matters

• Proper lighting helps workers identify hazards and perform tasks safely.
• Damaged temporary lighting equipment can create electrical shock and fire hazards.
• Poorly routed extension cords increase the risk of trips and falls.
• Proper lighting placement improves productivity while reducing accidents.
• Routine inspections help identify damaged equipment before injuries occur.

Common Hazards

• Damaged light fixtures, bulbs, or extension cords.
• Overloaded electrical circuits.
• Portable lights placed where they can be struck or knocked over.
• Extension cords creating trip hazards.
• Temporary lighting exposed to water or wet environments without appropriate protection.
• Insufficient lighting causing poor visibility.
• Missing bulb guards or damaged protective cages.
• Unauthorized modifications to lighting equipment.

Safety Checklist

Before Work Begins

• Inspect temporary lighting equipment, cords, plugs, and fixtures for damage.
• Verify lights are suitable for the work environment and electrical supply.
• Ensure protective guards or cages are installed where required.
• Position lights to provide adequate illumination while minimizing glare and shadows.
• Route extension cords to avoid walkways or protect them from damage if they cross travel paths.
• Ensure Ground Fault Circuit Interrupter (GFCI) protection is used where required, especially in damp or wet locations.

During Work

• Keep lighting fixtures stable and protected from impacts.
• Do not hang lights by electrical cords unless they are specifically designed for that purpose.
• Keep combustible materials away from hot light fixtures.
• Replace burned-out bulbs only after power has been disconnected and the fixture has cooled, when applicable.
• Report damaged lighting equipment immediately and remove it from service.
• Adjust lighting as work locations or conditions change.

Crew Talking Points

• Is today's temporary lighting adequate for every work task?
• Have all lights and extension cords been inspected before use?
• Are lighting cords creating any trip hazards?
• What should you do if a temporary light becomes damaged during the shift?
• Where is GFCI protection required on this jobsite?
• Speak up immediately if you notice damaged lighting equipment or inadequate visibility.

Stop Work If

• Temporary lighting is damaged or malfunctioning.
• Electrical cords have exposed conductors or damaged insulation.
• Lighting is inadequate to safely perform the task.
• Fixtures are unstable or at risk of falling.
• Electrical hazards cannot be adequately controlled.
• You are unsure whether the temporary lighting is safe to use.

Final Reminder

Temporary lighting should improve safety—not create new hazards. Inspect lighting equipment before use, provide adequate illumination, protect electrical cords, use GFCI protection where required, and remove damaged equipment from service immediately. If you cannot clearly see the work, stop and correct the lighting before continuing.
