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
120-130 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
