Falling objects: Objects such as tools and building materials can fall from a height and cause severe injuries or fatalities.
Weather: Wet weather and ice can increase the risk of slips and trips. Wind can also blow tools and debris off the worksite, which can hit people on the ground.
Overhead power lines: Direct contact with power lines can be fatal, but even getting too close can cause dangerous electrical shocks or flashovers.
Insufficient protective equipment: Poor or inadequate protective equipment can increase the risk of falling and lead to fatal accidents.
Debris chutes: Tools and debris can create a trip and fall hazard, especially if someone falls off scaffolding.
Unprotected edges and openings: These can be a hazard when working at height.
Fragile surfaces: These may not be able to support weight.
Sharp edges: Sharp edges on structures can be a hazard.
Obstacles or structures overhead: These can be a hazard when working at height.
Vehicles in motion: Vehicles moving near the worksite can be a hazard
