Question

there are ways to protect yourself when excavating. which of the following is a way to protect yourself when working around excavations? select the best option. slope or bench the sides of the excavation and support the sides of the excavation. have another employee declare the excavation safe. support systems, shield systems, or other protective systems should be used only when the excavation is 10 feet in depth or deeper. place a shield outside the work area.

Explanation:

Sloping, benching and supporting excavation sides are standard safety - measures to prevent cave - ins and protect workers. Having another employee declare safety is not a reliable method. Protective systems should be used as per regulations and not just when 10 feet deep. Placing a shield outside the work area does not protect workers in the excavation area.

Answer:

Slope or bench the sides of the excavation and support the sides of the excavation.
