What this inspection record means

OSHA opens inspections for many reasons: routine scheduling under a national or local emphasis program, an employee complaint or referral, or a follow-up after a reported injury. Opening or conducting an inspection is not itself an allegation or a finding that this employer broke any rule; any findings appear as the citations listed below, and citations can be contested, reduced, or withdrawn.

29 CFR 1926.651(k)(1): Daily inspections of excavations, the adjacent areas, and protective systems were not made by a competent person for evidence of a situation that could have resulted in possible cave-ins:    (a) Kiewit Infrastructure Co., at 4595 E. 46th Ave, Denver, CO 80216: On or before February 26, 2020, the employer did not ensure that employees working inside a trench with one nearly vertical wall with multi-layered soil were protected from cave-in, in that the employee used a shovel to remove soil from a pre-existing water line in the bottom of the trench.  The water line at the bottom of the nearly vertical wall measured approximately 8 feet, 3 inches, and was previously disturbed.  The competent person failed to classify the soil as previously disturbed and failed to access the need for adequate protection for the exposed, nearly vertical wall containing multi layered soil during his daily inspection. This condition exposed employees to a crushing hazard by excavation wall cave-in.

Kiewit Infrastructure Co., at 4595 E. 46th Ave, Denver, CO 80216: On or before February 26, 2020, the employer did not ensure that each employee replacing a section of a water line, inside a trench, with one nearly vertical wall, that measured 8 feet, 3 inches in depth, was protected from cave-in.  The employer sloped the 3 other sides of the trench, however a nearly vertical wall, on the north side of the excavation was left unprotected, in that the nearly vertical wall consisting of multi-layered soil, was left exposed and unprotected. The employer had not complied with the provisions of 29 CFR 1926 Subpart P, Appendix B, Table B 1.4, in that, all excavations 20 feet or less in depth made in layered soils shall have a maximum allowable slope for soil or rock deposit. The maximum allowable slope associated with Type B soil is an angle of 45 degrees or 1:1 from toe to top. The employer had not complied with the provisions of 29 CFR 1926.652 Subpart P, Appendix B, Table B 1.4, Excavations Made in Layered Soils. This condition exposed employees to a crushing hazard by excavation wall cave-in.
