ALARP meaning

In practice, ALARP describes the duty to reduce a risk to a level that is as low as reasonably practicable, weighing the foreseeable risk against the time, trouble and cost of further reduction. It aligns with the statutory “so far as is reasonably practicable” (SFAIRP) duty in UK health and safety law and is interpreted through case law (notably Edwards v National Coal Board). ALARP is widely applied in UK risk assessment and safety cases, and is central to nuclear and radiation protection. The Environment Agency (EA) and the Office for Nuclear Regulation (onr) treat ALARP and ALARA as equivalent in radiological contexts. A typical ALARP demonstration follows a structured options assessment: define and characterise the problem; identify potential options; assess their risk‑reduction benefits, impacts and proportionality; select and justify the preferred option(s); implement and keep under review. Where design affects safety and the environment, regulators often accept an integrated assessment combining ALARP and Best Available Techniques (BAT), as their objectives overlap. Jurisdiction: usage is consistent across England & Wales, Scotland and Northern Ireland. In Ireland, radiation protection law primarily uses ALARA under EU Basic Safety Standards; the underlying concept of reasonable practicability informs Irish health and safety practice.
