Integration of risks from multiple hazards into a holistic ALARA/ALARP demonstration

Area of Science:

• Occupational Health and Safety
• Risk Management
• Environmental Science

Background:

• The principle of As Low As Reasonable Achievable (ALARA) originated in radiological protection but is now applied to all hazards in the UK.
• Current hazard assessment methods are often isolated, making a holistic risk view difficult.
• UK regulations require risks to be reduced to ALARA or As Low As Is Reasonably Practicable (ALARP).

Purpose of the Study:

• To propose a framework for the integrated assessment of risks from multiple hazards.
• To address the challenge of demonstrating holistic risk reduction to ALARA/ALARP levels.
• To provide an overview of challenges in achieving a comprehensive ALARA demonstration.

Main Methods:

• Development of a proposed framework for integrated risk assessment.
• Review of current methodologies for hazard assessment.
• Analysis of challenges in holistic risk management.

Main Results:

• A framework for integrated multi-hazard risk assessment is presented.
• Key challenges in demonstrating holistic ALARA/ALARP compliance are identified.
• The need for a unified approach to risk assessment is highlighted.

Conclusions:

• Integrated risk assessment is crucial for meeting ALARA/ALARP requirements.
• The proposed framework offers a pathway towards more holistic risk management.
• Addressing identified challenges is essential for effective implementation of ALARA principles.
