When we think of accidental falls, we often think of work at-height. But fall accidents can happen anywhere there is a change in level – and that includes confined spaces.

Many industries have tight spaces that are considered by OSHA to be "confined" because they are configured in such a way as to hinder the activities of anyone who is called upon to enter, work in, and exit them.

Obviously, not only do confined spaces vary in size, shape and location, but they can come with their own set of challenging conditions, including limited movement, hazardous air, and risk of engulfment.

OSHA identifies a broad range of confined spaces, including that ubiquitous example: the manhole. As soon as the cover from a manhole is removed, any lack of proper safety equipment puts anyone at an increased risk of falling through an unguarded opening. Once within that particular type of confined space, there exists the risk of falling still deeper. Outdated ladders or stairs, inadequate lighting, and the physical challenges posed by restricted movement are all potential contributing factors to fall injuries within confined spaces. Fumes – a major safety consideration for any kind of confined space – have the potential to overwhelm anyone working near the area, leading to a loss of consciousness and the likelihood of a fall.

Other types of confined spaces defined as such by OSHA include ducts, tanks, vessels, storage bins, vaults, tunnels, and silos, to name a few. What is consistent for all of them is a need to consider the same level of fall protection as for any above-ground work involving changes in level. Even in confined spaces, having an effective fall protection system can significantly reduce the risk of injury. Depending on the situation, safeguards such as barriers, guardrails, and devices such as self-retracting lifelines or lanyards can prevent or halt accidental falls. In determining whether a confined space calls for the use of such equipment, it is necessary to evaluate both the area within the confined space and its access point.
