In the animal feed industry, hammer mill machinery plays an important role in the smashing of raw materials. By 2017, in an animal feed industry there has been a fire on the dust collector that almost burned down the hammer mill machine. In previous years also often occur sparks arising due to the knife rubbing against the metal that carried away with raw material. However, the fire will not increase if the hammer mill machine operators are competent in extinguishing the fire. The purpose of this study is to find out how much the effects of hammer mill machine fire fighting in terms of safety scenarios that exist either from human procedures or automatic safety procedures performed by existing safety devices. In this study, using a combination of calculations between Human Error Probability (HEP) values obtained from Human Reliability Assessment (HRA) calculations using SPAR-H method and reliability calculation of hammer mill machine components obtained from downtime data for four years, 2014 until 2017. The total probability of outcome fire controlled increases from 0.177940 to 0,6393 and the total probability of outcome fire uncontrolled decreases from 0,82206 to 0,36068.
