In my opinion, the most dangerous job is construction workers. Society is growing, the more buildings are built. Many accidents happen at the construction site. Workers often work under huge steel beams, even hovering in the air. The most fatal accident in the construction site was falling from the ground. In addition, fire, electric shock, noise, altitude, temperature is too high or too low, light is too bright or too dark, dust, asbestos ... are also dangerous sources for construction workers .
