Safety Surveys and Health Hazards Identification among Construction Workers : A Case Study of Residential Construction Site in Khon Kaen Province

This survey study aimed to identify safety management and health hazards in construction by using a case study of residential construction in Khon Kaen province. There were five sites of construction where were included of three processes of construction i.e. earthwork & foundation, structure work, and system & decorating work. Data were collected by using the safety checklist survey in a total of 80 construction workers working in five construction sites. The structure process needed the highest proportion of workers (68.75%). Wearing personal protective equipment according to the risk job was found in the highest proportion at the structure work (50.00%). Earthworks & foundations and system & decorating works met the standards of working environment and facility (62.50%). The standard of engineering control of earthworks & foundations (54.54%) was similar to system and decorating works (52.63%). The major causes of health hazards in constructions were from machines and tools and health effects were struggling, crashing, materials falling on and falling from high level. These findings suggest the owners to focus on injuries and accident prevention espicially from machines and tools. In addition, engineering control is also important measure including scaffolders, temporary panel boards, ladders, welding equipments, and gas cylinders. The safety signs and personal protective equipments should be provided appropriate to the hazards at work. The results of safety survey and health hazards identification are useful for risk assessment on work injuiries.
