SCBA and Fire Fighter PPE FFII Training Hillcrest Station
Oxygen Deficiency Oxygen deficiency Normal O2 is 21% 17% some muscular impairment and increase respiration 12% dizzy, headache and fatigued 9% Unconsciousness 6% Death
Elevated Temperatures degrees reduced B/P, circulatory failure Inhalation of hot gasses pulmonary edema (swelling) death from asphyxiation
Smoke Made up of Tar Carbon Dust Some particles are irritating, some are lethal Size of particle determines how deeply it gets into the lungs
Toxic Gasses Gas combinations will be different at each fire May cause Disease of lung tissue Impair RBC ability to carry O2 Gasses given off determined by Nature of combustion Rate of heating and temperature O2 concentration at time of combustion
Carbon Monoxide Found at every fire Colorless and odorless Result of incomplete combustion More deaths occur from this than any other product of combustion Prevents O2 from attaching to hemoblobin 500ppm dangerous
Carbon Monoxide – Care Symptoms Flu-like Need O2 immediately
Hydrogen Chloride Colorless gas Pungent Causes swelling of upper respiratory tract Comes from burning PVC Very dangerous during overhaul Latent heat can cause plastics and electrical cables to decompose after fire is out
Hydrogen Cyanide (HCN) Interferes with respiration at cellular level and tissue level Colorless, almond scented gas Emitted by Wool, nylon, polyurethane foam, rubber, paper Concentrations above 270 ppm almost immediately fatal
Carbon Dioxide Nonflamable, Colorless, Odorless Paralyzes brain’s respiratory center Watch out for CO2 flooding systems
Nitrogen Oxides Nitric Oxide NO and Nitrogen Dioxide NO2 Nitrogen Dioxide Reddish brown gas, known as silo gas Released from plastics Cause pulmonary edema React with water to form acids Irritating effect often tolerated while inhaling fatal dose
Phosgene COCL2 Colorless, tasteless gas Disagreeable odor Generated when freon comes in contact with flame Generates Hydrochloric Acid when it comes in contact with water
Dangerous Building Conditions Fire Spread Combustible furnishing and finishes Heavy Fire Load Large open spaces (hard to vent or stop spread) Weakened support members Water build-up Building Collapse
Electrical Emergencies Downed power lines Contact with electric lines Energized equipment
Handling power emergencies Notify power company No solid streams Treat all lines as live Avoid working under lines if possible Keep aerial equipment 10 feet away from lines Provide one span danger zone around lines
Functions of protective clothing Helmet with face shield Protective hood Protective coat and pants Gloves Boots PASS
Limitations of protective clothing Depends on material Direct flame contact Chemicals Comfort
Inspection and care of equipment
Fireground Accidents Trauma Heat Exhaustion Chemical exposure Cardiovascular
Responding and Returning Hearing Falls Slipping Run over by apparatus Thrown from apparatus
Training Same as fireground Physical discomfort or illness
Nonfire emergencies Trauma Chemical Exposure Electrical contact
Personnel Accountability System Allows for accounting of all personnel on fire scene Uses tags or badges Standard procedure for “handing over ID” List of who is doing what What happens when I’m done or when I leave the scene
Procedures for save environment Redesign tasks to eliminate lifting Use proper lifting techniques Be aware of unsafe conditions and attempt to fix them Eliminate horseplay Request assistance Strive for good health/fitness Be aware of proper disinfecting techniques
