Risk assessment in a metal processing factory in Malaysia

Abstract

This paper evaluates the workplace hazard and safety and analyzes the case studies that happened in a metal manufacturing company. Type of incidents include fire, explosion and trapping in between objects in which one of the employees were reported death crushed by the die casting machine and the explosion of the furnace of the die casting machine. Root cause analysis techniques like Fish Bones technique was used to determine machine, method, materials, environment and personnel of the five hazards in the workplace. HIRARC analysis is performed by highlighting the hazards such as not wearing protective mask and gloves, smoking at workplace, entangled wires cable of machine, operating injection moulding machine insufficient space around furnace in the HIRARC analysis. After Pareto analysis was carried out, it was found that operating injection moulding machine shows the highest risks followed by working around furnace. The incidents can be avoided if the workers are more exposed to SOP of the operation of the machine and protective measures are taken.
