Resumo:
INDUSTRY, ECONOMIC AND PUBLIC-HEALTH CONTEXT CHANGES, ALONG WITH TECHNOLOGICAL ADVANCEMENTS PRESENT A UNIQUE OPPORTUNITY TO REVISIT TRADITIONAL HAZOP SESSION TECHNIQUE, AIMING AT ITS CONTINUOUS IMPROVEMENT, SO UPCOMING RISK ASSESSMENT CAN CULMINATE IN MORE ROBUST AND TANGIBLE RESULTS. WE FIRST INTENDED TO GATHER PERCEIVED DEFICIENCIES OF THE WELL-KNOWN HAZOP TECHNIQUE, TO ULTIMATELY ENHANCE IT, BY PROPOSING AND TRIALING NEW MECHANISMS, AND COVERING GAPS BETWEEN THEORY AND PRACTICE. BASED ON EXPERIENCED HAZOP FACILITATORS’ AND ATTENDEES’ OPINIONS, RECURRING DEFICIENCIES WERE IDENTIFIED, NAMELY: PARTICIPANTS’ LIMITED UNDERSTANDING OF THE TECHNIQUE, LOW ENGAGEMENT, EXTENSIVE SESSIONS, UNPRODUCTIVE RISK CATEGORIZATION AND UNFRIENDLY PRESENTATION OF RESULTS. THIS ASSESSMENT OUTLINED THE BASIS FOR THE PROPOSED IMPROVEMENTS: FACILITATOR HIGHER ACCOUNTABILITY AND PREPARATION; VISUAL MEDIA TO PREPARE ATTENDEES IN PRE-SESSION, ALSO AN OPPORTUNITY TO COLLECT INDIVIDUAL ASSESSMENTS OF PERCEIVED RISKS THROUGH FORMS; OPTIMIZED SESSION TIME, USING DIGITAL TOOLS TO PRODUCTIVELY ACHIEVE CONSENSUS; RESULTS PRESENTATION IN A MORE INTUITIVE FORMAT, ALLOWING EASIER TRACKING OF FOLLOW UP ACTIONS. THIS MODIFIED HAZOP TECHNIQUE HAS BEEN PARTIALLY APPLIED TO AN FEL3 PROJECT IN MINING INDUSTRY, CONDUCTED REMOTELY. RESULTS SHOWED THAT PRE-SESSIONS HELPED PARTICIPANTS WITH LIMITED HAZOP KNOWLEDGE TO CONTRIBUTE, WHILE THE TECHNICAL REGISTER INDIVIDUAL FORMS ALSO LEVERAGED MORE CONTRIBUTION FROM EXPERIENCED COLLABORATORS. AS A RESULT, SESSIONS WERE MORE COMPREHENSIVE AND TIME-EFFICIENT. THE PARTIAL APPLICATION OF THE MODIFIED TECHNIQUE YIELDED SIGNIFICANT GAIN AND INDICATES THE POTENTIAL OF THIS TECHNIQUE FOR FUTURE STUDIES.
