Abstract: Amends Construction Standards for Excavations, 29 CFR part 1926, subpart P to establish requirements for protection of employees in excavations. Effective Date: 1/2/90. Existing standards regulate use of support systems, sloping and benching systems and other systems of protection against cave-ins; means of access to and egress from excavations; employee exposure to vehicular traffic, falling loads, hazardous atmospheres, water accumulation, and unstable structures in and adjacent to excavations. Revised standard uses performance criteria where possible; consolidates and simplifies many existing provisions; eliminates duplicate provisions and ambiguous language; provides consistent method of soil classification; gives employers added flexibility. Text includes Tables showing timber requirements for trench shoring and alluminum hydraulic shoring requirements. Figures illustrate slope and bench configurations and supports; hydraulic shoring installations, trench jacks and shields. A graphic summary of requirements for excavations 20' or less in depth is contained in Appendix F.
