This section discusses the composition of first responders, excluding the media, and the importance of pre-incident planning for gathering and storing information about properties for emergencies.
Focuses on prioritizing life safety hazards in different occupancies and defines fire according to the Fire Code of the Philippines as a rapid oxidation process.
Explores methods of heat transfer like radiation and identifies clues in arson investigations, such as the absence of carbon monoxide in a deceased victim's blood.
Questions cover methods used to prepare for arson, such as 'plants,' and define concepts like fire suppression and abatement in fire control.
Discusses different types of fire extinguishers, specifically carbon dioxide, and clarifies legal charges like murder or arson based on the intent and circumstances of the fire.
Defines organic peroxide as a strong oxidizing compound and clarifies 'boiling point' in arson investigations as the temperature where vapor pressure equals atmospheric pressure.
Identifies removal of valuable articles as an indication of intentional fire-setting and confirms that arson can be consummated even with minimal damage if the fire has started.
Explains 'lamp black' in fire query (soot from burning oils) and differentiates between frustrated, consummated, and attempted arson based on the extent of execution.
Details the composition of AFFF (Aqueous Film-Forming Foam) and introduces 'evaluation size-up' as on-the-spot planning for emergency situations.
Defines Class A fires involving common combustible materials and identifies 'free burning' as the fire stage with the highest intensity.
Explains pyrolysis as decomposition by heat and identifies R.A. 9514 as the Fire Code of the Philippines.
Highlights the function of a damper in duct systems to restrict smoke/fire and defines convection as heat transfer in fluids.
Discusses fire 'magnitude' related to flame size and burning area, and 'alligatoring' as a burnt pattern in wood indicating intense burning.
Prioritizes securing the fire scene in investigations and describes standpipe systems for fire suppression water supply.
States that most arson cases rely on circumstantial evidence and defines 'detonation' as a supersonic explosion with a shock front.
Describes a vertical shaft as an enclosed passage extending from floor to floor and explains 'spalling' as concrete/brick breaking due to intense heat.
Identifies asphyxiation as the leading cause of fire deaths and defines 'backdraft' and 'flashover' as critical fire phenomena.
Defines combustible liquid by its flash point and introduces 'overhauling' as the process of checking for remaining ignition sources to prevent rekindling.
Explains fission as heat energy from splitting atoms and identifies ammonia as a chemical element used by arsonists to hide flammable liquid odors.
Distinguishes between 'attempted arson' based on actions taken before ignition and defines 'accelerants' as chemicals facilitating flame propagation.
Explores 'lamina flame' characteristics and describes the normal vertical movement of fire in a building.
Identifies chemical energy as the most common heat source in combustion and 'fire partitions' as barriers separating hazardous occupancies.
Defines 'ember' as a hot, oxidizing lump without flames and emphasizes 'raising the alarm' as the primary course of action in case of fire.
Assigns responsibility for fire code inspection to the Chief Fire Safety Enforcement Section and defines 'fire suppression' as pacifying a fire.
Describes fire inspection to assess safety from destructive fires and 'duct system' as a continuous passageway for air transmission.
Recommends 'aerial' ladders for high-rise firefighting and 'friction heat' as a cause of fires from machinery or hard surfaces.
Defines 'conflagration' as an extensive fire and prioritizes locating the point of origin after firefighting operations.
Illustrates a 'premixed flame' with a bunson burner and defines a 'fire hazard' as any condition increasing fire probability or hindering firefighting.
Identifies yellow flame color with burning calcium and defines 'containment' as restricting fire spread within a building.
