Introduction to Confined Spaces

Sometimes, construction workers are required to work in confined spaces. A confined space is any area which is large enough for a person to enter, but small enough so that a person has limited or restricted entry or exit, and which is not designed for someone to stay in for long periods of time. The constricted nature of these areas makes them more dangerous simply for the reason that they are more difficult to leave in an emergency, but also because smaller spaces do not typically have the same air flow that a larger room would have. These conditions can allow for toxic gas build-up or oxygen deprivation. It is also easier to get trapped in a confined space, since in the event of a cave-in or flood, there are fewer options for escape. Examples of confined spaces include manholes, elevators, tanks, ducts, vaults, and many others.

The goal of this course is to help you understand the risks involved in entering and attending a confined space. We will review many of the potential hazards you might encounter, the equipment and methods to monitor and avoid these hazards, and how to secure the area before and after entry.
