Text For Citation: 01 Item/Group: 002A Hazard:

29 CFR 1910.147(c)(4)(i): Procedures were not developed, documented and utilized for the control of potentially hazardous energy when employees were engaged in activities covered by this section: (a) Owens Corning Roofing and Asphalt, LLC at 5201 Fox St., Denver, CO: On and around June 18, 2019, the employer developed and documented but did not utilize procedures for the control of potentially hazardous energy, when employees were working with steam to unclog pipes on an asphalt surge tank and coating system. Employees were exposed to splash hazards from liquid asphalt that was heated to 375 degrees Fahrenheit, when water was introduced to the surge tank from the clog steaming operation and the asphalt erupted from the top of the tank. The suction valve at the bottom of the tank and the downstream asphalt pump were not locked out to prevent the introduction of water into the bottom of the surge tank. This condition resulted in four employees being exposed to hot asphalt splash hazards and each suffering multiple skin burns. (b) Owens Corning Roofing and Asphalt, LLC at 5201 Fox St., Denver, CO: On and around June 18, 2019, the employer developed and documented but did not utilize procedures for the control of potentially hazardous energy, when employees were working with steam to unclog pipes on an asphalt surge tank and coating system. During the application of steam to a clogged pipe, the steam line became clogged with asphalt. Employees decoupled the steam line from the pipe system and attempted to clear the steam line blockage. The steam system was not locked out and de-energized prior to employees attempting to clear solid asphalt from the steam line. This condition potentially exposed employees to burn and struck-by hazards from steam and solid asphalt particles in the steam line, which was pressurized at 80 pounds per square inch.
