Summary
Investigation of hydrogen sulphide exposure during an orifice plate change at MP 299-B. A leaking meter-run gate released gas, repeatedly overcoming the lead operator, who fell through the ladder cage. The report identifies absent job analysis, monitoring, respiratory protection and mentoring, and records operator measures to prevent recurrence.
