Subject: SEMI EHS GRAPEVINE - Silane Fire and Explosion
FYI. Sunedison Pasadena TX which was formerly MEMC had a silane explosion and fire injuring 4 people. This occurred during a line break. I am trying to get more details. As luck would have it, I'm presenting on Pyrophoric Materials on Oct 23 at the Hotzone HazMat Conference in Houston.
A month ago in another silane related incident, a user used an industrial vacuum cleaner to vacuum SiO2 particles from a baghouse. This exploded severely burning the worker. SiO2 particles can develop a significant charge, in addition some are not fully oxidized.
These are reminders that we all must be careful when handling silane.
