THE APPLICATION OF HAZARD IDENTIFICATION AND RISK ANALYSIS (HIRA) AND FAULT TREE ANALYSIS (FTA) METHODS FOR CONTROLLING OCCUPATIONAL ACCIDENTS IN MIXING DIVISION DEWA-DEWI FARM
ABSTRACT: Occupational
accident is one thing that should be avoided, considering occupational accident
has very harmful effects for boh the company and the labours. Dewa-Dewi Farm is
a poultry farm which has four main divisions, which is mixing division is one
of them. There are 5 main activities in
mixing division, such as receiving and testing, weighing, grinding, mixing and
distributing the feed. All work
activities work in mixing division potentially bring out accidents. Identify Hazards is necessary to minimize accidents. Hazard identification and risk analysis (HIRA) is a method of
identifying hazards potential that may occur
in a job. By using HIRA known that the five main activities potentially
face risk of occupational accident such as earaches, muscle injury, shortness
of breath, sore eyes, slipping, falling, strucking, electric shock, burns and
skin allergies. After identifying the problem with HIRA method is completed
then carried out a risk assessment based on two criteria: likelihood
(probability) and severity (impact) should be done. Based on the risk
assessment there are 2 extreme-risk, 7 high risk, 4 medium-risk and 12 low-risk
activities. The next method used is Fault Tree Analysis (FTA) which is a method
of error analysis by direct observation and interviews, which then were
visualized with a model of the fault tree. Analysis of the causes of accidents
using FTA method shows the source of the risks posed by unsafe action and
unsafe condition that is the wrong way of working and poor working environment.
There are several recommendations given such as instructional the best way
about manual lifting, provision of tools and personal protective equipment, and
improve the working environment.
