The means of entry and exit can be evaluated before entry by checking
drawings, by prior knowledge, or simply by inspection from outside the space.
Confined space openings are generally small and not well located. These small openings must be considered in the rescue plan since they restrict the movement of workers and equipment in and out of confined spaces.

Entry and exit for top-side openings may require ladders. Ladders must be well secured. Performing an emergency rescue of workers trapped in such areas requires careful planning and practice.
