Can OSHA permit a contractor to use tabulated data from a registered professional engineer if their sloping angle exceeds the standard?

• A. Yes
• B. No
• C. Only if the data is recent
• D. Depends on the engineer's credentials

Answer: (A)

The correct answer indicates that OSHA can indeed allow a contractor to use tabulated data from a registered professional engineer, even if the sloping angle exceeds the standard requirements. This allowance is based on the assumption that the registered professional engineer has the requisite expertise and credentials to provide reliable data that is tailored to the specific soil and site conditions.

Utilizing tabulated data from a professional engineer can be beneficial when the standard slopes do not adequately address the conditions present at a particular excavation site. The engineer’s assessment can help ensure safety by providing custom solutions that account for unique variables, such as soil type, moisture content, and of course, the specific sloping angle which may differ from the general safety standards.

OSHA recognizes the importance of utilizing qualified professionals to assess and determine excavation safety measures beyond standard angles, provided that the engineer's data is detailed, accurate, and based on solid engineering principles.
