HAZARD IDENTIFICATION & RISK ASSESSMENT (HIRA)
In every manufacturing process which is sequences of activities to produce tangible products, manufacturers need natural resources and human resources. During the manufacturing process that always involves human resources, natural resources, and list of equipment, there are list of potential hazard that can occur.
Hazard is any existing or potential condition that can lead to injury, illness, or death to people, damage to or loss of a system, equipment, or property or damage to the environment. Since loss of economics value and fatalities of human are one of hazard effect, manufacturers has to know list of potential hazard and method to overcome occur hazards. An effort to overcome this issues start with hazard identification and risk assessment.
What is HIRA
Hazard identification and risk assessment. HIRA is a process of steps often followed to identify risks, assess consequences and likelihood, in order toreduce risks to an acceptable level.
HIRA Objective
The objective of this Hazard Identification Risk Assessment (HIRA) is to identify and assess the hazard associated with the construction of the project and thereby control the risk by implementing mitigation measures before the start of the work to avoid incidents. HIRA helps to become proactive rather than just reactive.
Steps of HIRA :
· Classify work/assessment units or work activities during the construction phase (based on Work Method Statement).
· Identify the hazards associated with work activities.
· List out the Consequence of the hazard involved in the activity.
· Assess and score the risk (i.e. probability X severity) using the Risk Matrix as per TPL Risk Assessment Matrix.
· List out present controls (preventive and recovery).
· Assess the risk based on present controls.
· Reassess the medium and high risk to bring it down to acceptable risk.
· Verify compliance to regional Regulations, Project Specifications, and applicable international codes and standards.
HIRA Risk Matrix
For each of the identified hazards, the level of risk is assessed based on the TPL SHE Risk Assessment Matrix (see Figure 6.3) during the HIRA review. Risk ranking is firstly performed based on the unmitigated risk for each hazard, and then the level of risk is re-evaluated after taking into consideration of the existing prevention/mitigation measures and controls.
If the risk is in the Green region on the TPL SHE RAM, this is broadly acceptable and no further action is required. If the risk is in the Yellow region on the TPL SHE RAM, this is in the tolerable regions and needs to be demonstrated to be As Low As Reasonably Achievable (ALARP) by recommending further action. If the Risk is still in the Red region, this is not acceptable and action definitely needs to be taken. HIRA Review team shall discuss the proposed actions, where applicable, to address the hazard that is ascribed with a medium to high-risk rating.
Control measures
Controls are required to be separated into preventive and recovery. Controls are required to be categorized using the hierarchy of controls (eliminate, substitute, isolate, engineering, administrative, and PPE).
This allows a review of controls to ensure the principle of inherently safer construction is being applied.
When
thinking about your HIRA remember:
· A hazard is anything that may cause harm,
such as chemicals, electricity, working from ladders, an open drawer, etc;
· The risk is the chance, high or low, that somebody could be harmed by these and other hazards, together with an indication of how serious the harm could be.
