The Top Four Construction Hazards


• Wear and use personal fall-arrest equipment when working in elevated locations 

• Install and maintain perimeter protection 

• Use ladders and scaffolds safely 

Crushing Accidents 

• Never position yourself between a moving object and a fixed one 

• Always wear high-visibility clothes near equipment and vehicles 

Trench Failures 

• Never enter an unprotected trench or excavation five feet deep or deeper without an adequate protective system in place. (Some trenches under five feet deep may also need such a system.) 

• Make sure the trench or excavation is protected either by sloping, shoring, benching, or trench shield systems 


• Locate and identify utilities before starting work. 

• Look for overhead power lines when operating any equipment. 

• Maintain a safe distance from power lines; learn the safe distance requirements. 

• Do not operate portable electric tools unless they are grounded or double insulated. 

• Use ground-fault circuit interrupters (GFCI) for protection. 

• Be alert to electrical hazards when working with ladders, scaffolds, or other platforms.
