Study Notes

Overview of Confined Space Procedures

Establishes guidelines for first responders dealing with confined space operations to ensure safety.
Emphasizes that first responders shall not enter confined spaces under any circumstances.

Definition of Confined Space

Limited or restricted means of entry or exit.
Not designed for continuous human occupancy.
May contain hazardous atmospheres or materials that can cause engulfment or entrapment.

Examples of Confined Spaces

Manholes, utility vaults, tunnels, sewer systems.
Wells, trenches, open pits, sump pits, silos, storage bins.
Brewer vats, septic tanks, caves, mines, tank cars, industrial smokestacks.
Other examples include cold storage facilities, ship holds, auto repair lift pits, and water treatment plants.

Hazards Associated with Confined Spaces

Atmospheric Hazards:
- Difficult to see, smell, hear, or feel; may include oxygen deficiency/enrichment.
- OSHA defines flammable atmospheres as containing gas/vapor above 10% of LFL or LEL.
- Toxic substances exceed permissible exposure limits; details vary by substance.
Physical/Mechanical Hazards:
- Examples include electrical risks, high water, steam, collapse, smoke/fire, darkness, and moving machinery.
- Other potential hazards are hypothermia, high noise levels, vibrations, and exposure to hazardous materials.

Responsibilities of First Responders

Establish Command: Take initial control of the situation upon recognizing a confined space emergency.
Size-Up the Situation:
- Recognize confined space emergencies and activate the Technical Rescue Team.
- Gather critical information regarding the type of space, victims, and on-site conditions.
Site Control and Scene Management:
- Isolate and deny entry to the confined space, establish a hot zone of 150 feet.
- Create staging areas for incoming units, maintain access for TRT, and control utilities affecting victims.
- Prepare to call for additional resources as needed (e.g., specialized teams, utility companies).
Identify Hazards:
- Recognize hazardous atmospheres, materials, temperature extremes, and physical risks.
Establish Communications:
- Communicate with victims only without entering the confined space.
- Personnel near the entrance must wear appropriate PPE, including SCBA.
