Some of the accidents that cause catastrophic injuries, permanent injuries, and death at construction sites include: Being struck by an object. Construction workers are at constant risk of being struck by objects since construction work regularly involves working on higher floors, trees, and elevated locations. Falling tools, debris, and equipment can cause severe injuries or deaths. Falling objects is the primary reason most construction workers wear helmets. Falls from the same ground level. Workers are constantly working on uneven surfaces, filling holes, installing new structures. When construction workers fall, they can suffer catastrophic injuries. Falls from higher levels. Workers who work on scaffolds, ladders, in the trees, and other above-ground places may die if the fall is from a high height. Survivors often suffer injuries that last a lifetime. Vehicle accidents. Trucks, bulldozers, cranes, forklifts, and other moving vehicles need to be operated with care. The construction site needs to supervise the work all vehicles do so that accidents don’t injure or kill any of the workers. Defective products. Construction workers use many different electric tools and mechanical tools. They work with heavy machinery. Workers should have advanced skills to use these products. Even the most skilled workers can suffer an electrocution, broken bones, burns, or other injuries if the tools, machines, and equipment are defective. Toxic chemicals can cause severe skin disorders and respiratory disorders. Many construction workers suffer repetitive stress injuries.
