Ted should be wearing a self-contained breathing apparatus​

Answer 1

D. Ted should be wearing a self-contained breathing apparatus​

Step-by-step explanation:

According to this question, Ted has entered into an empty pit in order to do some maintenance work and his colleague, Sam, is outside the pit ready to assist him in case of emergency.

It is necessary to take additional precautions even if Ted is tied to a lifeline or the pit is empty. However, the additional precaution should be that Ted should be wearing a self-contained breathing apparatus​ (SCBA) in case of breathing or respiratory problems down the pit.
