Narrative
At 19:30 local time (mst), a low-level explosive limit (lel) alarm was received by the operations control center which initiated a callout from occ to field personnel to investigate. Technicians were dispatched to the location, confirmed the alarm, vented the building until it was safe to enter, and inspected the premises to determine the source of the alarm. The technicians discovered oil leaking from the sampler skid, which was flowing along the floor of the building down-gradient to the sump, where all released product was collected and recovered. All product released was confined to the building. The technicians determined that the source of the leak was an improper seal of the stainless steel tubing in a compression fitting on the sampler skid. The failed compression fitting and tubing were replaced and all other like fittings on the skid were inspected for proper seal.
