Incident Date
Describe the incident, including corrective steps taken and their result.
A hose clamp failed on a low-pressure vent line from a hydrogen reactor experiment and effluent was leaked into the laboratory. Unburnt hydrogen in the effluent stream triggered the low-level hydrogen alarm. The hose clamp was resecured and other hose clamps were checked for proper tightness.
Lessons Learned
Maintenance on the low-pressure venting system was not occurring at regular intervals. Ventilation integrity is now checked before starting an experiment.
