Study Notes
- Limiting access to fire scenes is important for safety.
- Hazard control zones include cold, warm, and hot zones.
- The fire perimeter is staffed by police to keep unauthorized people away.
- Incident conditions determine the dimensions of the fire perimeter.
- Electrical hazards are common at fire scenes.
- Firefighters should take immediate action to warn others of electrical hazards.
- Failure to warn others of electrical hazards can lead to electrocutions.
- Firefighters should treat all downed power lines as if they are energized.
- Firefighters should wear appropriate personal protective clothing and footwear when dealing with electrical hazards.
- Water should not be applied directly to electrical equipment that is burning or arcing.
- Modern synthetic fuels in residential occupancies burn faster and progress to flashover conditions much sooner than fuels found in mid-20th-century homes
- Structural firefighting tactics are based on materials found in homes 50 or more years ago
- Fires in a less-ventilated room would go into decay as the fire consumed available oxygen
- Probability of saving lives in the fire compartment is greatly diminished when firefighters arrive after flashover
- Larger rooms with different furnishings may take longer to reach flashover conditions, allowing more time to conduct rescue activities on the interior
- Providing additional air by opening doors, windows, and roofs could lead to a rapid increase in combustion in a ventilation-limited fire compartment
- Structural stability and survivability were not tested during UL experiments
- Structural stability is compromised as the fire continues to burn through the growth phase to the fully developed phase
- Structural stability is highly dependent on construction methods and materials
- The longer the fire burns, the greater the risk to firefighters and occupants.
- Fire growth and time are critical factors in building and structural fires.
- Occupant survival probability is low after a structural collapse due to fire.
- Different fuel configuration, ventilation profile, or structure type/size can change fire time value and curve configuration.
- Building fires involve contents while structural fires involve actual structural members.
- Fires progress from building fires to structural fires during the progression to flashover.
- Fires entering concealed spaces present many problems.
- Concealed fires can harm firefighters by cutting off their egress.
- Table 5-5 lists time variables from ignition to effective actions on the fire ground.
- The time variables are subject to change depending on local resources and fire conditions.
- Brannigan's Building Construction for the Fire Service distinguishes between building and structural fires.
