CSB Published Update on 2023 Geismar, LA HF Release

Yesterday, the Chemical Safety Board announced the publication of an update for their investigation of the 2023 explosion and toxic chemical release at the Honeywell facility at Geismer, LA. The update provides background information on the process involved, a summary of the incident timeline, and a description of the damage that resulted from the accident.

It is interesting to note that the Board’s investigators are having to rely on Honeywell investigation data for much of the physical data related to the incident. This is because there was a significant delay in the initiation of the Board’s investigation; the Board announced the start of the investigation in April, 2023. In early 2023, the Board was still fully engaged in clearing the investigation backlog that plagued the Board since before 2021.
