___Is a developed skill that helps you predict fire behavior
Smoke leaving a structure has four key attributes:
Volume, velocity (pressure), density, and color
_______often leads to combustion
Surfaces that are smoking, not burning, are ___________.
_______Are the more prevalent solids in smoke
Soot and ash
___Is Carbon, (officially carbon black) and Carbon can support flaming
The trace metals and minerals, depleted salts, that can no longer support flame
From most interior fires, the volumetric composition of smoke is mostly________.
An _______can be defined as a suspended or propelled liquid
Hydrocarbons give smoke a____color
Satin wet black
Some very common hydrocarbons in smoke can self-ignite as low as 450°F, but they often do not ignite because the particulates have made the smoke too rich to burn. This makes smoke a typical house fire_________.
Smoke is ignitable as low as___and has a collective flammable range of_to_in air!
Self ignition temperature of carbon monoxide
Self ignition temperature of hydrogen cyanide
Self ignition temperature of benzene
Self ignition temperature of Acrolein
Two triggers may cause accumulated smoke to ignite :
The right temperature and the right mixture
Smoke gases that are below their ignition temperature but above flashpoint need only a proper air mix and a sudden spark or flame to complete their ignition, called a_____ignition
The ignition of smoke that has pressurized a room or box likely result in an __________
The ISO who watches what the smoke is doing makes better decisions than the one focused on flaming, because the smoke tells you how intense the fire is about to become as opposed to how bad it currently is
The avenues that heat, smoke, flames, and combustion air follow
A compartmentalized fire condition where open flaming decreases because smoke production displaces and limits available combustion air, although heating continues to produce smoke
*introduction of air will cause the fire to rapidly transition into an explosive growth phase
A rapidfire growth phenomenon that occurs when combustion air is reintroduced into a ventilation controlled fire, leading to smoke flame over and room flashovers
Explosive growth phase
A proactive solution to prevent the explosive growth phase includes_____, which is the application of water to ceilings and walls to help quench and cool moving smoke
Some call this the fuel limited phase.
A hostile event warning sign and is characterized as the intermittent ignition of small pockets of smoke, usually seen as fingers of flame that dance through the upper smoke Layer
Ghosting is not necessarily a hostile our event but serves as a warning sign of impending?
Flashover or flame over
A hostile fire event that includes the ignition insisting burning of the overhead smoke a layer within a room and/or hallway
A hostile fire event that occurs when a spark or flame is introduced into a pocket of smoke that is below ignition temperature but above some aggregate flashpoint
Smoke flame over upon the breaking of windows or opening of the doors is a late sign of?
Explosive growth phase
