According to OSHA, at what trench depth must means of egress be provided?

  1. 3 feet

  2. 4 feet

  3. 5 feet

  4. 6 feet

The correct answer is: 4 feet

According to OSHA regulations, means of egress must be provided for trenches that are 4 feet deep or more. This requirement is put in place to ensure the safety of workers who may be entering or exiting trenches, as the risk of hazardous conditions, including potential cave-ins, increases with depth. By mandating egress systems, such as ladders, stairs, or ramps, OSHA aims to facilitate safe access to and from these trenches, thus reducing the likelihood of injury. Understanding these guidelines is crucial for ensuring compliance and maintaining a safe work environment in construction operations involving excavation work.
