The development of an operational safety case involves the effective identification, evaluation and control of potential hazards, as well as a positive argument to justify the various choices that have been made to provide for the facility’s operational safety.
A key consideration of the safety case system is the “ALARP” concept, which requires employers to reduce the risk of hazards to As Low As Reasonably Practicable. “Reasonably practicable” roughly means ‘reasonably possible without undue disproportionate economic cost for the minimal benefit to safety.’
