The NFPA standard that regulates water-based fire suppression systems -
ANSWER👀 NFPA 13
Flammable gases, vapors of ignitable liquids, combustible dusts, backdraft
explosion, and aerosols are examples of fuels often involved in what type of
explosion? - ANSWER👀 Chemical Explosion
A type of toxicity exposure that involves a low-level of continuous exposure -
ANSWER👀 Chronic
The type of electrical system that involves a current flowing in a loop or complete
circuit. - ANSWER👀 Closed
These materials produce essentially the same flame temperature as ignitable liquids.
- ANSWER👀 Combustibles
A rapid oxidation process, as opposed to slow oxidation - ANSWER👀 Combustion
A type of gas that is liquefied under pressure for storage and is heavier than air (1.5
to 2.0 vapor density) - ANSWER👀 Commercial Propane
A solid explosive that is characterized by high pressures, crushing effects, and
typically pronounced seats - ANSWER👀 Condensed-Phase Explosive
,Explosions involving a solid--as opposed to a diffuse fuel--in which the fuel and
oxidizer is mechanically mixed or the material itself can be rapidly and molecularly
converted - ANSWER👀 Condensed-Phase Explosion
These provide a pathway for current to flow in an electrical system - ANSWER👀
Conductors
These two conditions are essential for an outdoor vapor cloud explosion to occur,
otherwise the ignition of the flammable cloud would merely produce a flash fire -
ANSWER👀 Congestion and Confinement
The typical location on a circuit where electrical overheating is most likely to occur
(eg. loose connection or resistive oxide at the connection) - ANSWER👀 Connection
Points
Inhalation, cutaneous, ingestion, injection and ocular are the five routes of what? -
ANSWER👀 Contamination
A device in an RV that transforms AC to DC - ANSWER👀 Convertor
A type of toxicity exposure that involves repeated exposure over time - ANSWER👀
Cumulative
A fire pattern in a wildfire, where the grass or foliage is beveled on the side facing the
fire - ANSWER👀 Cupping
, The most common reason for children playing with fire - ANSWER👀 Curiosity
A legal challenge to the reliability of expert's opinions, utilized to discover the
method's testability, peer-reviewed, error rate, and community acceptance -
ANSWER👀 Daubert Challenge
The weight of the building's materials - ANSWER👀 Dead Load
A permanent covering over a boat's compartment/ hull - ANSWER👀 Deck
A type of blastwave that is subsonic and does not produce a shockwave -
ANSWER👀 Deflagration
The two main classes of combustion explosions - ANSWER👀 Deflagration and
Detonation
A legal procedure that is part of discovery and seeks to obtain and preserve a
testimony - ANSWER👀 Deposition
A type of oxidation reaction and chemical explosion that produces a shockwave -
ANSWER👀 Detonation
A type of blastwave that is supersonic and produces a shockwave - ANSWER👀
Detonation
The most common pressure regulator in a fuel gas system - ANSWER👀 Diaphragm
