ALARP in COMAH

• For practical purposes
• All Measures Necessary (AMN)SFAIRPALARP

Existing Guidance

• HSE has produced a suite of guidance documents
  concerning ALARP. These are designed to give high
  level principles which D/Ds can then use to
  promulgate sector specific advice.
• The documents are
• Reducing Risk, Protecting People (R2P2)

8
Existing Guidance (continued)

• Principles and guidelines to assist HSE in its
  judgments that duty-holders have reduced risk as
  low as reasonably practicable
• Assessing compliance with the law in individual
  cases and the use of good practice and
• ALARP in Design - Policy and Guidance.

Annex 3 of R2P2 reflects the ALARP
guidance e.g. the concept of 'hypothetical

ALARP Demonstration

• But the higher the installation lies on the
  societal concerns scale the greater the need to
  look for additional measures, over and above the
  normal standards.How to approach?
• 1. Identify risk reduction measures.
• 2. Assess using Lines Of Defence analysis with
  cost estimates
• 3. Possibly, in extreme cases, add a Cost
  Benefit Analysis.
