The perception of risk in construction workers|La percezione del rischio negli operatori edili

Accidents in building sites led us to study risk perception in workers employed in this field. We disposed of 300 workers, aged 18-65, who had to answer to a questionnary were signing among seven risks the more present in their activity, chosing among five levels. So for each risk the worker had to quantify parameters such as: danger, frequence of accidents, actitude to risk-control, training on risk. The risk of falling from high sites has bben perceived as extremely dangerous but it is possibile to control it. Less dangerous is eyes esposition to chemical agents or dust. Manual movimentation of weight and lacerations would be teh most frequent source of accidents. Moreover would be insufficient the capacity to control teh rick related to Weight manual movimentation and vibrations. Workers answered in questionnary that risk training on vibration was not sufficient, on the contrari they knew the risk of falling from high site. So we conclude that to reduce accidents in building sites it is necessary make better training on field, modifying the individual behavior among tworkers.
