Key Hazards
- Workers not seen by drivers, operators, or equipment spotters
- Poor visibility from darkness, fog, rain, snow, dust, smoke, or glare
- Blind spots around vehicles, equipment, materials, or structures
- High-visibility clothing not worn, dirty, damaged, or covered
- Lighting creating shadows, glare, or hidden hazards
- Communication failures between workers, drivers, and equipment operators
2–3 Minute Talk Script
Low-visibility operations make it harder for workers to be seen and harder for workers to detect hazards around them.
Low visibility can come from darkness, fog, rain, snow, dust, smoke, glare, indoor lighting problems, or blocked sight lines.
High-visibility clothing should be worn when workers are exposed to vehicles, equipment, traffic, or other moving hazards.
High-visibility clothing must be visible to work. Dirty vests, covered reflective strips, faded material, or dark outer layers can reduce protection.
Lighting should be placed to improve visibility without blinding drivers, operators, or pedestrians. Poor lighting can create deep shadows or glare.
Workers should stay out of blind spots and should not assume they are visible just because they can see the vehicle or equipment.
Spotters, radios, hand signals, cones, barricades, and work lights may be needed when visibility is limited.
Safe low-visibility work depends on high-visibility clothing, lighting, communication, controlled movement, and stopping work when workers cannot be reliably seen or detected.
Safety Reminders
- Wear high-visibility clothing when exposed to vehicles or equipment.
- Keep reflective material clean and visible.
- Use lighting that reduces shadows and glare.
- Stay out of blind spots.
- Use spotters or radios when visibility is limited.
- Slow down equipment and vehicle movement.
- Stop work if workers cannot be seen clearly.
Ask the Crew
- What is reducing visibility today?
- Can drivers and operators see workers clearly?
- Is high-visibility clothing clean and uncovered?
- Are lighting, shadows, or glare creating hazards?
- What communication or spotting method is needed?
