Hazard Identification & Risk Assessment (HIRA)

Hazard identification and risk assessment (HIRA) study offers the systematic approach to assess hazards and their associated risks that may offer an objective measure of an identified hazard as well as provide a technique to manage the risk.

Why HIRA Study

To identify all the factors which may cause harm to workers.
Consider the probability of incidents and assessing their severity
Identify the existing safeguards and controls.
Assess the risks and to make sure they are within acceptable limits.
Recommendation to effectively counter the possibility of hazards

Inputs Needed

HIRA id highly dependent on the availability and accuracy of the input data, with more complete input data providing a higher confidence on the validity and robustness of the results obtained. The example of data collection will be specific to operations, building design, personnel / population occupancy levels.

HAZID Methodology

The study method is a combination of identification, analysis and brain storming based on the hazards identified which is divided into four main sections containing several categories. The generally applicable categories are;

Section 1 External and Environmental Hazard;
Section 2 Facility Hazards;
Section 3 Health Hazards and
Section 4 Assess Risks to:
- People
- Asset /Production
- Environment

The known hazards will be listed and checked within the risk matrix to grasp the importance of risk, the safeguarding controls / measures will be described based on the risk ranks and at last the recommendation shall be provided to prevent / eliminate the potential hazards. The risk matrix used for the study is given below,

Likelihood rating

Likelihood	Description	Rating
Most Likely	The presumably result of the hazard/event being realized	5
Possible	Has a good probability of occurring and is not unusual	4
Conceivable	Might occur at some time in future	3
Remote	Has not been identified to occur after several years	2
Inconceivable	Is practically not possible and has never occurred	1

Severity Rating

Severity	Description	Rating
Catastrophic	Numerous fatalities, irretrievable property damage and productivity	5
Fatal	Approximately one single fatality or major property damage if hazard is realized	4
Serious	Non-fatal injury, permanent disability	3
Minor	Disabling however permanent injury	2
Negligible	Minor abrasions, bruises, cut, first aid type injury	1

Risk Matrix

Risk Rating

Risk	Description	Action
15 – 25	HIGH	A HIGH risk needs immediate action to manage the hazard as detailed within the hierarchy of control. Actions taken to be documented on the risk assessment form as well as date for completion.
5 - 12	MEDIUM	A MEDIUM risk needs a planned approach to manage the hazard and applies temporary measure if needed. Action to be documented on the risk assessment form as well as date of completion.
1 – 4	LOW	A LOW risk could also be considered as acceptable and any reduction might not be necessary. However, if risk can be resolved quickly and expeditiously, control measures got to be enforced and recorded.

LSIR

Location specific Individual risk (LSIR) is that the risk for a hypothetical individual positioned at particular location for 24 hours on a daily basis 365 days per year. The LSIR criteria are employed in order to produce an over view of the long run industrial land use planning and developments. This individual risk is acquired directly from the risk software’s. The LSIR derived from risk software shall be supplied with the unit of Individual / societal Risk Frequency per year.

Risk Assessment Methodology

Risk Assessment is employed for risk management and safety improvement in several industries. It provides a quantitative assessment of potential risks known and provides a basis for evaluating process safety with reference to a planned risk acceptance criterion.

Approach to Risk Assessment

Facility design, function, location, capacity and layout.
Site environmental weather data.
Process engineering / plant operational details of every equipment at the location
Work force deployment, calculable occupancy and exposure.

Consequence Analysis & Recommendations

Consequence is that the measure of the expected outcomes of any accidental that cause the hazard to the individuals / asset / surroundings. This could be done by internationally accepted software with the precise results. Based on the results recommendation are going to be provided with reference to the international standards for each and every hazards.
