OSHA TECHNICAL MANUAL (OTM) - SECTION V: CHAPTER 2

From osha.gov

Introduction. Excavating is recognized as one of the most hazardous construction operations. OSHA recently revised Subpart P, Excavations, of 29 CFR 1926.650, 29 CFR 1926.651, and 29 CFR 1926.652 to make the standard easier to understand, permit the use of performance criteria where possible, and provide construction employers with options when classifying soil and selecting employee protection methods.
Definitions. A. Accepted Engineering Practices are procedures compatible with the standards of practice required of a registered professional engineer.
Overview: Soil Mechanics. A number of stresses and deformations can occur in an open cut or trench. For example, increases or decreases in moisture content can adversely affect the stability of a trench or excavation.
Determination of Soil Type. OSHA categorizes soil and rock deposits into four types, A through D, as follows: A. Stable Rock is natural solid mineral matter that can be excavated with vertical sides and remain intact while exposed.
Test Equipment and Methods for Evaluating Soil Type. Many kinds of equipment and methods are used to determine the type of soil prevailing in an area, as described below.
Shoring Types. Shoring is the provision of a support system for trench faces used to prevent movement of soil, underground utilities, roadways, and foundations.
Shielding Types. A. Trench Boxes are different from shoring because, instead of shoring up or otherwise supporting the trench face, they are intended primarily to protect workers from cave-ins and similar incidents.
Sloping and Benching. A. Sloping. Maximum allowable slopes for excavations less than 20 ft (6.09 m) based on soil type and angle to the horizontal are as follows
Spoil. Figure V:2-16. Temporary Spoil. Text version of Figure V:2-16. This figure illustrates temporary spoil being placed at a minimum of two feet from the surface edge of the excavation.
Special Health and Safety Considerations. A. Competent Person. The designated competent person should have and be able to demonstrate the following: Training, experience, and knowledge of
