What is the OSHA standard for excavation?
OSHA requires employers to provide ladders, steps, ramps, or other safe means of egress for workers working in trench excavations 4 feet (1.22 meters) or deeper. The means of egress must be located so as not to require workers to travel more than 25 feet (7.62 meters) laterally within the trench.
At what depth is shoring required?
5 feet
Trenches 5 feet (1.5 meters) deep or greater require a protective system unless the excavation is made entirely in stable rock. If less than 5 feet deep, a competent person may determine that a protective system is not required.
What specific OSHA standard states a stairway or ladder must be provided in an excavation 4 feet deep or greater every 25 feet of lateral travel?
Means of egress from trench excavations. A stairway, ladder, ramp or other safe means of egress shall be located in trench excavations that are 4 feet (1.22 m) or more in depth so as to require no more than 25 feet (7.62 m) of lateral travel for employees. Exposure to vehicular traffic.
Can I bench Type C soil?
Type C soil is cohesive with an unconfined compressive strength of 0.5 tsf or less. Examples include granular soils such as gravel, sand and loamy sand; submerged soil or soil from which water is freely seeping; and submerged rock that is not stable. Benching Type C soil is unacceptable and shall not be done.
Is a trench a confined space OSHA?

At what height does OSHA require a step?
Riser height shall be from 6 to 7.5 inches (15.24 to 19.05 cm), stair width a minimum of 22 inches (55.88 cm) between vertical barriers, tread depth a minimum of 12±2 inches (30.48±5.08 cm), and tread nosing shall be straight leading edges.
What is OSHA rate?
The Total Case Incident Rate (TCIR) is defined as the number of work-related injuries per 100 full-time workers during a one year period. OSHA uses the TCIR to monitor high-risk industries, and they also allow EHS managers to track incidents and discover patterns across different departments or facilities.
