Incident on Feb 27, 2021: Six employees sustain burns due to naptha fire

At 3:30 p.m. on February 27, 2021, a tractor trailer carrying a heat exchanger tube bundle attempted to cross a wooden ramp, meant to provide a temporary road crossing of Street A between Unit #6 and Unit #9 of the refinery. The ramp covered a two-inch threaded carbon steel pipe that connected the two units. The pipe was used to transfer sour Naphtha from Unit #9 manifold to Unit #6 LNHT stripper column. When employees attempted to use the temporary road crossing while moving the heat exchanger tube bundle, the piping was struck and displaced, resulting in the release of sour Naphtha, which ignited. Six employees were hospitalized for face and body burns.

The rules behind these citations

Current text from the Code of Federal Regulations. Some citations were issued under older wording.

29 CFR 1910.106 · Flammable liquids

29 CFR 1910.106(c)(3)

(3) Pipe joints. Joints shall be made liquid tight. Welded or screwed joints or approved connectors shall be used. Threaded joints and connections shall be made up tight with a suitable lubricant or piping compound. Pipe joints dependent upon the friction characteristics of combustible materials for mechanical continuity of piping shall not be used inside buildings. They may be used outside of buildings above or below ground. If used above ground, the piping shall either be secured to prevent disengagement at the fitting or the piping system shall be so designed that any spill resulting from such disengagement could not unduly expose persons, important buildings or structures, and could be readily controlled by remote valves.

29 CFR 1910.106(c)(4)

(4) Supports. Piping systems shall be substantially supported and protected against physical damage and excessive stresses arising from settlement, vibration, expansion, or contraction.

29 CFR 1910.106(c)(7)

(7) Testing. All piping before being covered, enclosed, or placed in use shall be hydrostatically tested to 150 percent of the maximum anticipated pressure of the system, or pneumatically tested to 110 percent of the maximum anticipated pressure of the system, but not less than 5 pounds per square inch gage at the highest point of the system. This test shall be maintained for a sufficient time to complete visual inspection of all joints and connections, but for at least 10 minutes.
