Defining Confined Spaces


Being aware of confined spaces and how they impact your building team is critical for any architect, engineering or construction professional. Based on OSHA’s definition, there are three key pillars to a confined space:

  • A space large enough and so configured that a worker can bodily enter and perform his or her assigned work. OSHA does not have a definitive standard for what is considered large enough, and instead bases judgments on the size of the various employees on a construction crew.
  • A space that has limited or restricted means for entry or exit. You are dealing with confined space entry if workers must use ladders or open a flange or latch and crawl in to an area. If there are doors that you can walk through while upright, or if stairs are present, OSHA does not consider that restricted.
  • A space that is not designed for continuous human occupancy. Areas without the ventilation and other basic requirements human habitation for hours at a time would fall under this category.

These confined spaces present unique safety challenges that you and your staff must be prepared to handle. Check out our Youtube video for more details, and consider RedVector’s construction training courses to get your entire crew up to speed on how to stay safe in confined spaces and beyond.
