Question

1. which of the following characteristics typical of a confined space? a. it has a limited amount of ventilation. b. there is no means of escape. c. it is too small to work in. d. it may be entered by untrained employees.

Explanation:

A confined space typically has limited ventilation. While it must have a means of entry and exit for safety (so b is incorrect), it is not necessarily too small to work in (c is wrong), and it should not be entered by untrained employees for safety reasons (d is incorrect).

Answer:

a. It has a limited amount of ventilation.
