Preliminary hazard analysis (PHA) is used primarily for:

Preliminary hazard analysis (PHA) is a systematic approach utilized in the early stages of a project to identify and assess potential hazards that could pose risks to safety and health. By conducting a PHA at this initial phase of planning, stakeholders can proactively recognize potential risks before they evolve into more significant issues. This forward-thinking method allows for the integration of safety controls and risk mitigation strategies into the design or operation of a project, ultimately aiming to prevent accidents or injuries from occurring.

While predicting environmental impact, determining financial risks, and evaluating equipment efficacy are essential aspects of a comprehensive safety program, they do not directly align with the primary objective of a preliminary hazard analysis. The essence of PHA is centered on the identification of hazards at the onset to facilitate safe planning, making it a critical tool in promoting safety and reducing risks in various industries.
