The study found that the risk in low level was 11.3%, medium level was62.9%, high level was 24.2%, and very high risk was 1.6%. There was only one job, cutting bar job which was invery high level of risk and there were 6 jobs in high level of risk such as scaffolding job, pouring concrete job,painting job, carrying material job, masonry job and bending bar job. All of 7 jobs must be managed to controlrisks in construction work by using safety activities which are appropriated in any jobs concluding in 3 terms; 1)management of appropriated personal protective equipments (PPE), 2) management of working area, and 3)management of equipments, hand tools, or machines in working. Moreover, an encouragement in term ofconcerning in safety is an important strategy for safety management in construction work. When applying 4safety programs, workers concern in safety issue. Moreover, the testing score of knowledge in term of personalprotective equipment increased from 4.96 to 7.00 points (sig. 0.05). When applying safety program in cutting barjob, the risk decreased to be 6 (in medium level) and when applying emergency plan, there are 5 activities fortaking a patient to a hospital between 16 to 22 minutes.
