12. two building trades technicians are discussing the use of ladders on the construction site. technician a says that aluminum ladders should be your first choice when selecting a ladder because they're lightweight, easy to maneuver, and lessen the risk of back injury. technician b says that wooden ladders should be your first choice since an aluminum ladder would conduct electricity if it makes contact with a power source. which technician is correct? o a. only technician b is correct. b. neither technician a nor technician b is correct. c. only technician a is correct. d. both technician a and technician b are correct.

The correct answer would be A, Technician B is correct.

Explanation:

Using Aluminum ladder on a construction site is not a good choice at all. It conducts electricity and can give a power shock to someone if electricity gets  conducted through it by any chance. Secondly, when it will be used on the construction site in open air under the sun, the aluminium ladder would get hot and workers wont be able to easily climb through it. Using wooden ladder would lessen the chances of any injury or casualty on the construction site due to electricity shock. So technician B is right who suggests that wooden ladder should be used instead of aluminium ladder.
