Construction activities are among the most hazardous operations in the industrial sector because they involve heavy machinery, working at heights, electrical systems, excavation, hazardous materials, and constantly changing work environments. Construction workers are exposed to various physical, chemical, biological, and ergonomic hazards that can lead to accidents, injuries, occupational diseases, and fatalities. Effective safety management, proper training, use of personal protective equipment (PPE), and strict compliance with safety regulations are essential to control these hazards. ## 1. Falls from Height Falls are one of the most common and serious hazards in construction work. Workers frequently perform tasks on scaffolds, ladders, roofs, platforms, and elevated structures. Lack of proper guardrails, unsafe scaffolding, improper use of ladders, and absence of fall protection systems can result in severe injuries or death. Common causes of falls include: * Unprotected edges and openings. * Poorly constructed or maintained scaffolding. * Slippery working surfaces. * Lack of safety harnesses and fall arrest systems. * Inadequate worker training. To prevent falls, employers should provide safe access platforms, install guardrails, inspect scaffolds regularly, and ensure workers use appropriate fall protection equipment. ## 2. Struck-by Hazards Struck-by accidents occur when workers are hit by moving objects, vehicles, or falling materials. Construction sites contain many moving components such as cranes, trucks, excavators, and lifting equipment, creating a high risk of impact injuries. Examples include: * Being struck by falling tools or materials from elevated areas. * Being hit by construction vehicles. * Contact with swinging loads during crane operations. * Accidents caused by flying objects during cutting or drilling activities.
