Hazardousrequires

Hazardousrequires is a term used in risk management to denote safety or hazard-related requirements that are essential to preventing or mitigating hazardous conditions. It refers to requirements whose non-fulfillment would create, worsen, or fail to mitigate an identified hazard. The term is not part of any formal international standard, and its meaning and use vary by organization and domain. In practice, hazardousrequires is invoked to flag critical safety controls within a requirements baseline and to prioritize verification and validation activities.

Scope and applications include process safety, product safety, and certain software safety contexts. It is commonly applied in hazard analyses, risk assessments, and requirements engineering to identify controls that have a high impact on overall safety. Examples might include automatic shutdown on overpressure, continuous gas detection with audible alarms, fail-safe interlocks, and data integrity checks that prevent unsafe operation. In software-related safety, hazardousrequires can refer to input validation, fault handling, and fail-operational behavior that protect users from harm.

Lifecycle and verification involve establishing traceability from each hazardousrequires to the associated hazard, risk rating, and safety function. These requirements are typically subject to stricter verification and validation activities, such as independent reviews, testing against hazardous scenarios, and demonstration of compliance with safety objectives. Changes to hazardousrequires usually trigger re-evaluation of risk and may require re-certification or re-approval in regulated contexts.

Relation to standards: hazardousrequires is not a standardized term, but it aligns with established concepts such as critical safety functions, safety requirements, and risk-based controls. Users should define its meaning consistently within their organization to ensure clear communication and proper safety governance.
