Which configuration can increase the risk of entrapment in confined spaces?

Entrapment in confined spaces can occur when there are configurations that allow personnel to become trapped or unable to exit quickly in case of an emergency. Sloping floors are particularly concerning because they can create scenarios where a person might lose their footing and slide into a lower area, leading to an inability to climb back up or escape effectively. The angle of a sloping floor can also make it difficult for an individual, especially if they are wearing safety gear or if the floor is slippery due to materials present.

In contrast, wide openings generally provide easier access and exit points, reducing the risk of being trapped. Multiple entry points can offer alternative ways to escape if one route is blocked, thereby minimizing entrapment risks. High ceilings typically allow for greater maneuverability and can reduce the likelihood of becoming trapped since there is more vertical space to move safely. Thus, while configurations like wide openings and high ceilings facilitate movement, sloping floors can present a significant challenge in ensuring safety and quick exits.
