(Washington, DC - January 14, 2003) A CSB investigative team is en route to the site of Monday's explosion in Brazoria County, TX, south of Houston that killed two workers and injured five others. The accident at BLSR Operating apparently involved two stationary vacuum tank trucks carrying petroleum wastes. CSB Chairman Carolyn W. Merritt is accompanying the team, which is headed by CSB Investigator John Vorderbrueggen. The team will assess whether to conduct a full CSB investigation of the incident, which would lead to a determination of causes and issuance of safety recommendations. Details to follow.
