Health hazards can de further classified into chemical, physical and ergonomic hazards.

Chemical hazards in the construction may develop from dust, fumes, fibers and liquids. They can be emitted by welding, spraying paint and using solvents. There also are hazards found in materials such as asbestos, lead, silica, cadmium and carbon monoxide. At the construction site, workers might be exposed to chemicals by breathing them in, ingestion and absorption through the eyes or skin. Chemicals at the construction work sites can cause headaches, eye irritation, dizziness, faintness, sleepiness and thus affect judgment and coordination.
Physical hazards in a construction zone include noise, vibration, extreme temperatures and radiation. Extended noise levels above 85 decibels can cause future hearing loss. Vibration harm typically occurs when workers use hand tools for extended periods. To prevent this, workers should take breaks and use earplugs to protect the body and ears from vibration and noise. In the site, extreme temperature changes can cause heat rash, fainting, heat cramps, heat exhaustion, heat stroke, frost nip, immersion injury, frostbite and hypothermia..

Ergonomic hazards cause disabling injuries to the joints and muscles. Ergonomic hazards occur most frequently in construction and contribute to the most injuries on job sites. These hazards occur because of heavy, frequent and awkward lifting or grips.
