ABI5010 – Certificate in Hazard and Operability (HAZOP) / Hazard Identification (HAZID) Studies (HAZOP/HAZIDCert)©

This course is a dual certification course focusing on Hazard and Operability (HAZOP) study and Hazard Identification (HAZID) as well known and well documented methods. In the first part of the course, participants will be acquainted with HAZOP study used to verify the integrity of design or procedures with respect to safety and operability. HAZOP, or Hazard and Operability Studies is one of a number of risk assessment techniques used to demonstrate compliance with health, safety and environmental standards and legislation

UNIT HH3: Students will submit an individual evidenced based HAZOP/HAZID report that includes research and contain at least 1000 words. It will be based on a practical assessment and include research it must be work related. Once the project is complete it must be forwarded to ABIOSH within 21 days of the last exam. This practical must include a cover sheet stating that it is the students own work and signed by the instructor
