    The CSB released a Factual Update on the April 2, 2019 explosion and fire at the KMCO facility in Crosby, TX. The CSB found that  a vapor cloud of isobutylene formed at the KMCO facility after a three-inch gray iron (a type of cast iron) y-strainer, a piping component, failed. The vapor cloud found an ignition source and ignited, causing an explosion.


    The explosion killed one KMCO worker and seriously burned two others. On the day of the incident, more than 200 KMCO employees, contract workers, and visitors were onsite. The incident injured at least 30 workers-seven KMCO employees and 23 contract workers. A shelter-in-place was issued to community members within one mile of the KMCO facility. The incident interrupted normal business operations at KMCO and resulted in two rounds of employee layoffs, reducing the number of employees at the Crosby facility from more than 180 to less than 50.

    The CSB investigation is ongoing. Investigators will continue developing the incident causal analysis based on evidence collected during the investigation. A final report, consisting of facts, analysis, conclusions, and recommendations will be issued at the completion of the investigation.

    The Factual Update is attached, and can also be found on the CSB website here: https://www.csb.gov/assets/1/17/csb_kmco_factual_update.pdf?16508
