In the future, refining, petrochemical, and chemical industries need to review material verification programs to ensure that the maintenance procedures include sufficient controls and positive material identification (PMI) testing to prevent…
After this accident, a safety inspection team was organized. An investigation of this incident and an inspection of all other experimental equipment was conducted by the team. As a result of this inspection, the heaters are now hard-wired to the…
Implementing and enforcing the laboratory's stop work and restart policy and procedures in conjunction with peer reviews for new processes and experiments should help prevent future accidents due to a lack of recognition of potential reactions…
Work documentation (work orders and baseline drawings) should reflect the current system configuration.
Recommendations
Because of the near invisibility of a hydrogen flame in daylight and hydrogen's extremely low ignition coefficient, if a known leak is present (e.g., an audible hissing), ignition should always be presumed. The primary cause of this incident…
This incident emphasizes the need for proper gas detection and ventilation systems, as well as fire suppression systems, in laboratories using and storing hydrogen. This is especially true when open flame burners are in close proximity.…
Several procedural and design changes should be considered for the future:
Key:
We are the leaders in the building industries and factories. We're word wide. We never give up on the challenges.
