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.
Trenching and Excavation Safety 1 Introduction Excavation and trenching are among the most hazardous construction operations. The Occupational Safety and Health Administration’s (OSHA) Excavation standards, 29 Code of Federal Regulations (CFR) Part 1926, Subpart P, contain requirements for excavation and trenching operations. This
The OSHA standard applies to all open excavations made in the earth’s surface, which includes trenches. According to the OSHA construction safety and health standards, 1926.650(b), a trench is referred to as a narrow excavation made below the surface of the ground in which the depth is greater than the width—the width not exceeding 15 feet (4.5
OSHA Excavation Standards. Construction activity of all types poses hazards that are subject to regulation by the Occupational Safety and Health Administration, or OSHA, which recognizes excavation as one of the most hazardous types of construction
Warning system for mobile equipment.When mobile equipment is operated adjacent to an excavation, or when such equipment is required to approach the edge of an excavation, and the operator does not have a clear and direct view of the edge of the excavation, a warning system shall be utilized such as barricades, hand or mechanical signals, or stop logs.

Sep 12, 2013· Rest assured if an OSHA Compliance Safety and Health Officer (CSHO) visits your jobsite and sees sloping has been selected as the protective system, he or she will measure the trench and determine the slope. Some CSHOs will use a rod and inclinator to determine the slope in degrees and others may just use simple calculations to calculate the slope.
Requirements Slope Configurations . Scope and Application. Specifications for sloping and benching, when used as methods of protecting employees working in excavations from cave-ins, are provided in this section. Definitions. Actual slope means the slope to which an excavation face is excavated.

Ramps are covered under OSHA guidelines 1926.451 and the general requirements mandated under sub section (e) (5). Ramps that measure more than 6 feet above lower levels (areas below the level at which a worker is working and could fall) should be equipped with guardrail systems.

All simple slope excavations 20 feet or less in depth shall have a maximum allowable slope of 1 1/2:1 Simple Slope. 2.All excavations 20 feet or less in depth which have vertically sided lower portions shall be shielded or supported to a height at least 18 inches above the top of the vertical side.
Mar 02, 2016· Engineer’s Corner: Providing Clarity for OSHA Requirements for Protective Systems 20 Feet or Deeper. One of the more interesting questions I receive from contractors well versed in both the excavation standard and manufacturer’s tabulated data regards the application of OSHA’s 20-ft depth requirement for site specific engineering.
Protective Systems in Excavation: Generally, in order to protect workers from cave-ins, OSHA requires employers to Slope and bench the sides of the operation, Support the sides of the excavation, or; Place a shield between the side of the excavation and the work area.
materials. If possible and practical, grade the slope away from the excavation. This serves a dual purpose of keeping equip-ment and vehicles from accidentally rolling into the excavation and directing rain water away from the excavation OSHA 1926.100(a) requires the use of hard hats where there
OSHA Standards for Ramps. Ramps are covered under OSHA standard 1926.451(e)(5) and 1926.651(c). Following is a summary of the guidelines for buildings under construction, during excavation, and the general requirements: In buildings under construction, ramps must be well lit while the construction is underway.
(2) Additional requirements for shield systems used in trench excavations. The sides of the shield shall extend a minimum of 18 inches above the vertical walls of compound excavations as shown in Appendix B, figures B-1, B-1.2 and B-1.3. On vertically cut trenches, the shield shall extend to at least the catch point of the trench.
TOSHA Training Services assist employers, employees, and their representatives in reducing safety and health hazards in their workplaces and in complying with the requirements of Tennessee OSHA standards and regulations. Join us in our effort of reducing safety and health hazards in your workplace.
Battering the excavation sides – Battering the excavation sides to a safe angle of repose may also make the excavation safer. In granular soils, the angle of slope should be less than the natural angle of repose of the material being excavated. In wet ground a considerably flatter slope will be required. Falling or dislodging material
All excavations or trenches of 4' or greater in depth shall be appropriately benched, shored, or sloped according to the procedures and requirements set forth in OSHA's Excavation standard, 29 CFR 1926.650, .651, and .652. Excavations or trenches 20 feet deep or greater must have a protective system designed by a registered professional engineer.
Mar 18, 2013· (2) “Toe of slope” means the point at which the side of an excavation intersects the lowest level of the excavation. (3) “Trench” means an excavation having a depth greater than its width measured at the bottom. (4) “Trench jack,” means a screw or hydraulic jack used as a
Look for the legislative requirements that apply in your jurisdiction and the type of protective measures to be taken. Sloping involves cutting back the trench wall at an angle that is inclined away from the work area of the excavation. The angle of slope required depends on the soil conditions. This option provides additional safety
