10. During a project walk with a insurance carrier safety representative, you come across a stub of 1/2-inch diameter conduit protruding about 18-inches from the slab. You believe that if someone falls onto the conduit they could be impaled or otherwise seriously injured. You ask the insurance carrier safety representative if OSHA might have a problem with the unprotected conduit stub. She replies that, while OSHA doesn't have a specific standard addressing this type of hazard posed by protruding conduit, OSHA would still likely issue a citation for the hazard. What is she talking about?(2.5 Points)

OSHA's "General Duty Clause" also known as "Section 5(a)(1) of the OSH Act."

OSHA would likely issue a citation under 1926 Subpart K, "Electrical Safety".

OSHA would likely issue a citation under 1926.95 for a lack of personal protective equipment.

OSHA would likely issue a citation under 1926.701(b).

14. You're speaking with your excavation subcontractor in a pre-mobilization meeting. You ask the subcontractor's competent person if they anticipate working in any confined spaces. They reply that they anticipate working only in manholes "occasionally" and perhaps in "live" manholes that are connected to sanitary sewer lines where there is a hazard of engulfment and a potential hazardous atmosphere.

27. If the excavation shown in the photo is made in Type C soil, and if the contractor chooses to use sloping as a means of protecting the workers, what is the minimum slope that they must have to comply with OSHA 1926 Subpart P, Appendix B?https://www.osha.gov/laws-regs/regulations/standardnumber/1926/1926SubpartPAppB(2.5 Points)

No, because there's not enough of it to cause and issues with nearby workers.

If it's windy enough, no. If it's not windy enough, maybe.

No. Dust is dust. Grow up and worry about stuff that actually matters.
