Hazard Identification and Risk Assessment
Hazard Identification Risk Assessment (HIRA) identifies and assess hazards during the construction of project, through controlling the risk by implementing mitigation measures before start of the work to avoid incidents.
HIRA is more a proactive approach than being reactive to worksite safety implementations.
Our site team will prepare an impressive HIRA along with proposed control measure on the basis of the Master HIRA. This will be prepared before start of each activity.
A HIRA must be updated after occurrences of any incident, management of change, change of work methodology and change of any regulation. If there is no change then it should be reviewed periodically.
The methodology of the HIRA review is the structured multidisciplinary hazard identification, risk assessment and methodology that provides a detail review of hazard, risk and control of the construction activities.
The review is facilitated by the relevant construction personnel in the brainstorming session
Steps of the HIRA review:
• Classify work/assessment units or work activities during 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, using a Risk Matrix.
• List out present controls (preventive and recovery).
• Assess the risk based on present controls.
• Reassess the medium and high risk to reduce it to an acceptable risk.
• Verify compliance to Regulation, Project Specifications, and applicable international codes and standards.
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.
For each of the identified hazard, the level of risk is assessed based on the Risk Assessment Matrix during 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.
Controls are required to be separated into preventive and recovery, and be categorized using the hierarchy of controls (eliminate, substitute, isolate, engineering, administrative, and PPE). This allows review of controls to ensure the principle of inherently safer construction is being applied.
