SCBA and Fire Fighter PPE

FFII Training

Hillcrest Station

oxygen deficiency
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
Elevated Temperatures
  • 120-130 degrees
    • reduced B/P, circulatory failure
  • Inhalation of hot gasses
    • pulmonary edema (swelling)
    • death from asphyxiation
smoke
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
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
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
Carbon Monoxide – Care
  • Symptoms
    • Flu-like
  • Need O2 immediately
hydrogen chloride
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
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
Carbon Dioxide
  • Nonflamable, Colorless, Odorless
  • Paralyzes brain’s respiratory center
  • Watch out for CO2 flooding systems
nitrogen oxides
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
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
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
Electrical Emergencies
  • Downed power lines
  • Contact with electric lines
  • Energized equipment
handling power emergencies
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
Functions of protective clothing
  • Helmet with face shield
  • Protective hood
  • Protective coat and pants
  • Gloves
  • Boots
  • PASS
limitations of protective clothing
Limitations of protective clothing
  • Depends on material
  • Direct flame contact
  • Chemicals
  • Comfort
fireground accidents
Fireground Accidents
  • Trauma
  • Heat Exhaustion
  • Chemical exposure
  • Cardiovascular
responding and returning
Responding and Returning
  • Hearing
  • Falls
  • Slipping
  • Run over by apparatus
  • Thrown from apparatus
training
Training
  • Same as fireground
  • Physical discomfort or illness
nonfire emergencies
Nonfire emergencies
  • Trauma
  • Chemical Exposure
  • Electrical contact
personnel accountability system
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
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
