A confined space is an enclosed or partially enclosed area that is big enough for a worker to enter. It is not designed for someone to work in regularly, but workers may need to enter the confined space for tasks such as inspection, cleaning, maintenance, and repair. A small opening or a layout with obstructions can make entry and exit difficult and can complicate rescue procedures. Some common examples of confined spaces that can be found in a workplace can include manholes, sewers, boilers, pipelines, tunnels, wells, storage tanks, trenches and silos, etc.
