Fire is an oxidation reaction from the meeting of fuel, oxygen and heat that causes losses, damage to equipment, death and disruption to business. The wood processing industry has a high fire risk due to the use of various kinds of machinery and raw materials. One effort to prevent and overcome fires is to conduct fire management training for all employees. This study aims to determine the differences in knowledge, attitudes and preparedness for fire prevention and control of workers before and after intervention is given. This research was conducted at PT. Maruki International Indonesia. The method of this research is quasi experiment with sampling using proportionate stratified random sampling technique. The research sample of 43 workers. Data were analyzed by paired sample T-Test with a significance level of 0.05 and the Generalized Linear Model (GLM) Repeated Measures. The results of the statistical analysis of the T-test from the measurement of workers' attitudes at the pre-test up to the 4th post-test showed no significant difference (p> 0.05). The results of the GLM Repeated measures statistical analysis indicate an increase in the attitude scores of workers (pretest-posttest) with the Greenhouse-geiser score F = 2.975, p <0.05. There is a significant influence of fire safety training on attitudes towards the workers of the production department of PT. Maruki International Indonesia. It is expected that the company will complete the fire protection system, conduct safety patrol and carry out regular fire safety training for workers.
