QUESTION 1
1.
Using sources found in the Required Unit Resources, develop a job hazard analysis (or job safety
analysis) for using a 4-inch grinder to remove mortar in masonry joints that need tuckpointing.
You must reach some areas by ladder and others by scaffold. List each step of the process, the
hazards for each, and how you would control the hazards for each step.
QUESTION 2
1.
Choose one of the high-hazard activities from the unit lesson that requires a competent person,
and describe the reasons for this requirement. In your answer, be sure to describe the role of the
competent person in controlling hazards, and include your process for inspection and the
frequency of the inspections.
QUESTION 3
1.
Consider that you are the competent person for your company, and you are installing some
underground storm drainage lines. You have an 8-foot-deep excavation that is 6 feet wide and 60
feet long in class C soil. The area you are working in is very limited, and it is hard to get your
equipment, such as backhoes, forklifts, and dump trucks into such a tight space.
It has been raining for the last week, and your foreman comes to you and tells you they can
bench the excavation (meaning to form horizontal steps instead of sloping) because the soil is
sticking together. There is also some water accumulation in the bottom of the excavation. Ladder
access/egress is the proposed means of getting into and out of the excavation. Other trades are
working nearby forming columns and must walk by the excavation often.
What is your response to the foreman, and why? What are the requirements for working in this
type of situation? Remember to use the Occupational Safety and Health Administration (OSHA)
standards to back up your response.
