Abstract

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.

Highlights

IntroductionIt discusses about fire risk assessment which is reviewed from fire emergency response scenario from existing safety device side [1][2][3]
In our industrial world, safety and occupational health are very important aspects
An accident that afflict to workers and production machines that occur during production in an industry can cause a disturbance in the work and can stop the production. It discusses about fire risk assessment which is reviewed from fire emergency response scenario from existing safety device side [1][2][3]

Summary

Introduction

It discusses about fire risk assessment which is reviewed from fire emergency response scenario from existing safety device side [1][2][3]. Based on other previous studies, it discusses about human error in work accidents using SPAR-H method. In this study only discussed about human error that can lead to work accident [4][5][6]. This study combines two approaches based on Heinrich theory i.e. component reliability and human error in the safety procedure scenario in case of fire. The probability of the existing safety device is calculated from the failure data that owned by the company, while the work that performed by the worker will be calculated using Human Reliability Assessment (HRA) with SPAR-H method. The purpose of this study is to determine how much the influences of unreliable components and human error in a fire incident, especially in the fire of hammer mill machine
