What is the difference between HIRA and JSA and HAZOP

Question

Accepted Answer

HIRA focuses on identifying hazards and assessing risks, JSA focuses on analyzing specific job tasks, and HAZOP focuses on identifying potential deviations in a process.

HIRA (Hazard Identification and Risk Assessment) is a systematic process of identifying hazards, assessing risks, and implementing control measures.
JSA (Job Safety Analysis) is a process of analyzing specific job tasks to identify potential hazards and develop safe work procedures.
HAZOP (Hazard and Operability Study) is a structured method used to identify potential deviations in a process that could lead to hazards or operability issues.
HIRA and JSA are more focused on day-to-day operational safety, while HAZOP is typically used for process safety in industries such as chemical and oil refining.
Example: In a construction site, HIRA would identify hazards like working at heights, JSA would analyze tasks like operating heavy machinery, and HAZOP would assess potential deviations in the construction process.
