Study Notes
Purpose and Authority
- Establishes procedures for response and mitigation of Liquefied Petroleum (LPG) and Natural Gas (NG) incidents.
- Authority given to the Fire Rescue Administrator.
Scope and General Information
- Applicable to all Emergency Operations personnel.
- Incidents may escalate into major emergencies causing fire, explosion, or evacuation.
- LPG/NG spreads rapidly, creates hazardous atmospheres, and can accumulate in confined spaces.
Characteristics of Natural Gas
- Also known as Methane; lighter than air.
- Fills spaces from the ceiling down; disperses quickly outdoors.
- Lower Explosive Limit (LEL) range: 5.3% to 14% by volume.
- Colorless and odorless; treated with Mercaptan for a rotten egg odor.
Characteristics of Liquefied Petroleum Gas
- Also known as Propane; heavier than air.
- Fills spaces from the floor up; remains low outdoors.
- LEL range: 2.1% to 9.5% by volume.
- Colorless and odorless; Mercaptan added for odor detection.
- Different tank sizes for various uses (20lb to 30,000lb storage).
Investigation Procedures
- Approach gas leaks upwind; avoid ignition sources.
- All personnel must wear bunker gear and SCBA for suspected leaks.
- First arriving unit responsibilities include establishing command, evacuating occupants, and atmospheric monitoring.
Atmospheric Monitoring
- Drager X-am 2500 4-Gas monitor used for detecting gas levels.
- Normal atmospheric conditions:
- O2: 21%
- LEL: 0%
- CO: 0 ppm
- H2S: 0 ppm
Confirmed LPG/NG Leak Actions
- Request additional resources (Battalion Chief, EMS).
- Establish Control Zones based on LEL readings.
- Ensure continued monitoring and adherence to safety protocols (two-in/two-out rule).
- Secure gas meters/tanks and inform gas company.
Responsibilities for Exterior LPG/NG Leak
- Consider requesting Special Operations assistance.
- Open flames from uncontrollable sources should be allowed to burn.
- Protect exposures and direct mitigation strategies.
- Cool LPG tanks to prevent BLEVE (Boiling Liquid Expanding Vapor Explosion).
Special Operations Team Roles
- Special Operations Captain to brief Incident Commander.
- Offensive measures may include grounding, clamping, and flaring off gas.
- Defensive measures involve waiting for LPG/NG company assistance.
Documentation Requirements
- Thorough documentation as per Incident Reporting protocols.
- Record gas monitor readings throughout the incident.
- Include information on any LPG/NG company technician present.
