OSHA 30 Hour Construction Program Practice Test

What describes an obstructed space in the context of confined spaces?

1. A space that is completely unobstructed

2. A space that is fully sealed

3. A permit space with some type of obstruction

4. A designated emergency exit path

The correct answer is: A permit space with some type of obstruction

An obstructed space in the context of confined spaces refers to a permit space that has some type of obstruction. This might include physical barriers or equipment that can hinder access or egress, affecting ventilation or the ability to maneuver within the space. Understanding this concept is crucial for safety procedures, as obstructions can create additional hazards, making it essential to evaluate and mitigate these risks before entry. The other choices do not accurately describe an obstructed space. A space that is completely unobstructed merely indicates there are no obstacles present, and a fully sealed space does not allow for entry or exit, which does not align with the definition of an obstructed space. A designated emergency exit path is not related to the physical characteristics of the space itself, but rather to the means of escape from it. Recognizing the characteristics of confined spaces assists in implementing safety measures to protect workers.
