ALARP
Chemical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: ALARP is an acronym for As Low As Reasonably Practicable, a principle used in risk management to reduce risks to a level that is tolerable and balanced against the cost, time, and effort of further reduction.
Example in context
“The risk assessment demonstrated that the remaining risk from the benzene storage tank was ALARP, with all feasible mitigation measures already implemented.”
“Risk değerlendirmesi, benzen depolama tankından kalan riskin ALARP olduğunu ve tüm uygulanabilir azaltma önlemlerinin zaten uygulandığını gösterdi.”
Where engineers use it
ALARP is a core principle in risk management studies, safety cases, and regulatory submissions for chemical plants. Engineers use it to justify that residual risks after mitigation are tolerable, balancing costs and benefits.
Synonyms: ALARP principle, as low as reasonably practicable
Practice: can you use “ALARP” at work?
A process safety engineer is reviewing the risk assessment for a new reactor. The hazards have been identified, and multiple safeguards are in place. The regulator asks whether the residual risk is ALARP. The engineer must explain the rationale.
Show a model answer
“Please confirm that the risk associated with this operation is ALARP.”
