Everyone who must enter a confined space for construction activities, maintenance, or other work must be properly trained. Additionally, workers must have regular refresher training in the spaces they will be working it.

Some examples of confined spaces are:Confined Space Training

  • Bins, boilers, and pits (elevator, escalator, and pump pits)
  • Manholes (sewers, storm drains, electrical, communications, and utility)
  • Tanks (fuel, chemical, water, grains, other solids or liquids)
  • Heating, ventilation, and air-conditioning ducts (HVAC)



OSHA considers a space to be confined when it:

  • Is large enough to enter
  • Has a limited means for entry and exit
  • Is not designed for continuous occupancy



  • Consultation, identification, and evaluation of confined spaces within your facility
  • Training customized to meet the needs of your organization and your confined spaces
  • Rescue plan development and team training
  • Standby rescue team services staffed by experienced professional first responders and rescuers

Why do we need an on-site team? Can’t we just dial 911?

While some workers rely on local emergency services (911) to be their rescue team, you leave more assumptions than certainties unless your agency forms a close working relationship with those agencies. Not all local emergency response agencies maintain a confined space rescue team. Some agencies share rescue resources, and it may take an extended period of time for the equipment and rescuers needed to arrive at the site. Additionally, the emergency responders may not know the unique hazards of the space where the work is being performed until an actual emergency is declared. Lack of familiarity with the space can lead to delays in rescuing a victim until the rescue team learns, understands, and secures all of the potential hazards.
