Areas that are considered confined space entry because their configurations hinder the activities of any employees who must enter, work in, and exit them. Employees who work in confined space entry areas generally must squeeze in and out through narrow openings and perform their tasks while cramped or contorted. Employees who work in these tight environments face increased risk of exposure to serious hazards. The area itself poses entrapment hazards such as asphyxiating atmospheres or the moving parts of machinery. OSHA uses the term confined space entry to describe such areas.
