Hazard Identification, Risk Assessment and Risk Control (HIRARC)
What is Hazard Identification, Risk Assessment and Risk Control (HIRARC)?
HIRARC is a method in which Hazards are determined, assessed and controlled in order to reduce or mitigate the severity of an event. It is used to prevent an incident, thus we consider this as proactive method. Those used to analyse an incident is more commonly known as a reactive method. The HIRARC method is widely used in Malaysia since the authority, the Department of Occupational Safety & Health (DOSH) has promoted this method since they were established. In the year 2008, DOSH has issued a guideline on how to conduct a HIRARC.
This guideline serves as a reference to safety practitioners on how to conduct a HIRARC with examples that could be related to the workplace. It also explains the terms and definition of each terminology used. It is a great learning tool to people who are new to the OSH field. Let’s look more into the details of the guideline.
This article is written in reference to the guideline under Item 2.0 Term and Definitions,
Hazard means a source or a situation with a potential for harm in terms of human injury or ill health, damage to property, damage to the environment or a combination of these.
Ask any safety practitioner in Malaysia, and they might probably give you the same answer, with the same exact wordings as this is a ‘must-know’ for them, otherwise they would not be able to pass the certification required by them. But, what does this actually mean? What is the definition about?
Let’s look into this scenario. A person is currently conducting welding works.
Based on the above definition, we can see that they are multiple sources that could cause harm to the welder himself, possibly to other peoples, property or environment around the welder. The sparks emitted by the welding process could cause damage to the welders eye. The sparks could also fly off and ignite the tank beside. The welder could be in contact with live wires which could cause him to get electrocuted. A lot of Hazards can be determined by just looking at the image.
A good safety practitioner would need to possess knowledge on the activity of works that is being conducted, in order to correctly analyse the situation, and correctly identify whether there is a hazard or not, and if there is a hazard, what would its impact be?
Risk means a combination of the likelihood of an occurrence of a hazardous event with specified period or in specified circumstances and the severity of injury or damage to the health of people, property, environment or any combination of these caused by the event..
We can say that for each action that we take, either drinking a cup of coffee, or driving to work, there are always risk associated with that action, in which could lead to a bad result for us. Risk is the chance of that something bad happening. Mathematically, risk is the likelihood times by the severity of that event.
For each event happening, we can determine its likelihood by analysing our past incidents data. How frequent does this event happen? How sever will this event impact us?
For each risk rating identified, we can determined whether it is a high, medium or low risk. This is better reflected inside the Risk Matrix as show below.
Hazard Identification, Risk Assessment and Risk Control (HIRARC) have become fundamental to the practice of planning, management and operation of a business as a basic part of risk management. This was recognized as proactive way of managing hazard and risk in daily operations or activites.
HIRARC 101 training will give the participant skills and knowledge on the best way of developing HIRARC for activities at workplace. This training also helps organisation on ensuring compliance to Malaysia’s Occupational Safety and Health (OSH) Law, as well as the International Occupational Health and Safety Management System Standard – OHSAS 18001.
According to DOSH Guidelines in Occupation Safety and Health Acts 1994 (OSHA), all organizations shall conduct HIRARC as part of the regulatory requirement set by the Government of Malaysia.
