Confined Space Emergencies

A confined space emergency is any occurrence inside or outside the space, including failure of hazard control or monitoring equipment, that may endanger authorized confined space entrants.

The period for successful rescue is very limited.

Believe it or not, during emergencies, rescuers end up as confined space fatalities more often than those being rescued. So, why is that? Fatalities can occur when the rescuers:

  • Are overcome by their emotions
  • Take unnecessary chances
  • Do not know the hazards involved
  • Do not have a plan of action
  • Lack confined space rescue training

It is important to know the period for successful rescue is very limited. Otherwise, a rescue attempt will become body retrieval. After only four minutes without oxygen, it is very likely a worker will experience asphyxiation, which may result in brain damage or death.

Preventing Confined Space Rescuer Fatalities

Planning the rescue is paramount. Make sure rescue team members understand their duties:

  • Practice, practice, practice!
  • Ensure the rescuer does not travel a greater distance than allowed by the air supply, self-contained breathing apparatus (SCBA), and escape cylinders.
  • Analyze distance, space configurations, physical obstacles, and total time needed to enter the space, perform rescue operations, and leave the space.
  • Leave the confined space immediately whenever a problem arises with respiratory protection equipment or whenever the attendant orders evacuation.

Everyone involved in a rescue should assume the space is deadly and entry rescue may be required in the worst case!
