At about 8am today, the Building 31 acid neutralization system buffer tank was found overflowing. The rinse water (with a pH of 2) overflowed the trenches in the building and started to flow out of the door onto the concrete pad. The SRF technician who found the spill started initial containment, and alerted other staff, including Industrial Hygiene personnel, to assist. The rinse water outside the area was quickly contained by trained SRF chemistry technicians. The incident was created by a faulty pH control system sensor. After the sensor was replaced, normal system operation resumed by about 11am. An event follow-up team is analyzing the release for lessons learned.
There were no injuries and no environmental impacts to the soil or drains.
