An observation of the mortality rate in the construction industry by age for the past five years shows that the mortality rate of those 50 years of age and older is consistently increasing. As the number of middle and old aged workers is continuously increasing, their hazard rate is also increasing so hazard prevention efforts for them are being urgently demanded. In particular, with regard to middle and old aged workers, there are many experienced in construction so wrong work methods or habits adopted in the past can cause hazards so safety education that can allow middle and old aged workers to adopt proper work methods or habits is urgently needed. At this, this study proposes a safety education model for middle and old aged workers that takes into consideration the characteristics of middle and old aged workers. The accuracy of the developed model was evaluated and its applicability was reviewed based on data. Verification of this proposed model was made by conducting a likelihood ratio test and correction rate test and likelihood ratio test results showed that all safety education elements were significant at a significance level of 0.1% and they also had a goodness of fit of 83%, so their potential for applicability in actual construction sites was verified. The accuracy of this model will increase as more data accumulates in the future.
