Lone working risks and hazards in construction industry

Falls, slips and trips

Falls from the heights are the most common cause of injury and death.

Being struck or crushed

Workers are crushed by falling objects and are stuck by lifting heavy loads or because of manual handling.

Exposure to loud noise

The communication between co-workers is difficult due to loud noise and hearing protection gear.


Cold or wet circumstances can reduce concentration and make manual tasks more difficult and put the lone worker in danger.
