Question

technician a says that you should always wear ear protection when using an air hammer. technician b says that standard wall sockets can be safely used with impact wrenches. who is correct?

o a. technician a
o b. technician b
o c. both technician a and technician b
o d. neither technician a nor technician b

Explanation:

Air hammers are noisy, so ear - protection is necessary (Technician A is right). Impact wrenches require high - power and standard wall sockets may not be rated for their load and can be dangerous, so Technician B is wrong.

Answer:

A. Technician A
