Law enforcement identified the site of the incident as belonging to KMCO, LLC, which identifies itself as a specialty chemical manufacturing and toll processing service "to many of the world's largest chemical companies."
According to its website, its east Harris County facility "has batch and continuous distillation and multiple reaction capabilities producing over 900 million pounds per year of toll manufacturing products."
KMCO also touts "investing significantly and leveraging our past 40 years of success to transform into a next-generation, best-practice driven company that meets and even exceeds our customers' expectations."
The sheriff's office later confirmed isobutylene, a colorless gas with a faint petroleum-like odor, was the chemical that ignited the fire at its Ramsey Road facility.
KMCO's president and CEO, John C. Foley, released a statement in the midst of the disaster response:
"There was an incident resulting in an ignition and fire today April 2, 2019 at KMCO, LLC in Crosby Texas. We are deeply saddened to confirm at this time that there have been injuries and one fatality. Those injured have been transported for medical treatment.
