The term “permit-required confined space” (permit space) describes that has one or more of the following characteristics: contains or has the potential to contain a hazardous atmosphere; contains a material that has the potential to engulf an entrant; has walls that converge inward or floors that slope downward and taper into a smaller area which could trap or asphyxiate an entrant; or contains any other recognized safety or health hazard, such as unguarded machinery, exposed live wires, or heat stress.
Confined space awareness training should be attended by supervisors who have employees that enter spaces, supervisors that have confined spaces in their work areas, and anyone who hires contractor's that will be entering PRCS (Permit Required Confined Space). Confined space awareness training should
also be included in new employee training.
Awareness to confined space is required especially with people that cannot handle the situation physically and psychologically.
Defining the requirements and the preparations for such places is important including any obstacles that might exist in order to prevent/minimize (being proactive) injuries and mistakes.
