g. DESCRIPTION: A fitting on a 5,000 gallon capacity holding tank failed due to unknown reasons. The incident resulted in a chemical spill to the concrete enclosure of a ground water remediation facility. At the time of the incident, the holding tank contained approximately 4,000 gallons of the listed product. Technicians from the parent company responded to the site. A fluid transfer from the damaged tank to a serviceable tank is in progress. Of the 20 gallon chemical spill, 19 gallons remained within the small outdoor concrete structure while an estimated 1 gallon leaked through the concrete block wall and onto the grounds of an adjacent property. No fires or injuries were reported and no personnel exposures took place. The Los Fire Department assisted on the call and an environmental specialist is en route to complete a cleanup. Permanent repairs are pending.
