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.
