A vacuum truck at the Santa Clara Waste Water plant near Santa Paula, California carried a white liquid substance that was highly unstable, prone to spontaneous combustion upon drying, and reactive to shock, pressure, water, and oxygen — conditions present during normal industrial operations.
On November 18, 2014, the rear of the vacuum truck exploded, releasing the unstable white liquid. Two workers were injured in the initial blast. The liquid spread and spontaneously combusted as it dried, generating a toxic smoke plume approximately three miles long.
Three responding firefighters were also injured during containment efforts. The toxic plume prompted closure of a local highway and evacuation of nearby residents and businesses, highlighting significant hazards associated with transport and handling of reactive chemical waste at industrial facilities.
