What risks need to be considered when rescuing someone from a confined space?
What Is a Confined Space?
A confined space is a workspace that limits free movement while working, especially with regard to safe entry and exit. A relatively large space like a railway tank car is still considered a confined space due to its single trapdoor entrance.
Who Is Allowed to Work in a Confined Space?
Usually these areas require technical experts such as mechanics, welders, or electricians, but every individual who enters a confined space must have received confined space training.

What Are the Biggest Dangers in Confined Space Rescue?
The primary danger can be the environment itself if toxic atmosphere, fire, crushing, or falling hazards pose an immediate danger to an individual. But the most universal danger is inadequate planning, preparation, training, and protocol, all of which must be established long before an individual enters a confined space.

What Risks Need to Be Considered When Rescuing Someone from a Confined Space?
- Immediate risks to life such as air shortage, poisons, potential explosions, potential electric shock, fire, water, crushing, or falling
- The status of the injured party (e.g. difficulty breathing, confusion, panic, inability to communicate) and the nature of the injury (e.g. broken bones, bleeding, head injuries, cardiac issues)
- The status of the rescue team (preparedness, availability, awareness of the location and its dangers)
- Ingress and egress dangers such as obstacles, static discharge, and hidden dangers
- The need to send additional people into the rescue scene – the more people in a confined space, the more dangerous it can become
- Safety gear – adequate ropes, pulleys and other hoisting equipment, correctly anchored and weight rated for the operation; breathing apparatus, safety clothing, and lighting charged, tested, and ready
- The carriage of bulky gear, such as breathing apparatus and ladders
- Corrosive atmospheres that might cause unseen structural damage to nylon harnesses, and metal objects that can be a source of spark or static discharge
- Tunnel vision and other distractions that can cause rescuers to get lost, injured, or use poor judgment
- Inadequate planning and training – every element of a confined space situation must be clearly and thoroughly analyzed, and all team members must have regular training and, in the case of CPR, certification
- Inadequate communication due to obstacles, noise, static, or darkness
Confined space situations are among the most dangerous workplace situations. When things go wrong, it can cost more than just the life of the injured worker. Procedures and plans must be regularly reviewed, with hands-on training required for all team members who may be involved in a confined space rescue, in any capacity.
