When fires occur, the most effective way to protect occupants is to _____
Extinguish the fire in its incipient stage.
For a special-agent extinguishing system to be considered successful, it must:
Completely extinguish the fire
A _____-_____ extinguishing system is used wherever rapid fire extinguishment is required an where reignition of the burning material is unlikely
Dry-Chemical
The Two application methods for dry-chemical extinguishing systems are:
Fixed System and Handheld Hoseline
Which type of Dry-Chemical Systems fixed systems is most common?
Local Application
_____-_____ agents are used in situations where water would be ineffective or reactive with the burning materials
Dry-Chemical
Dry-Chemical Extinguishing Agent: Also known as ordinary dry chemical and is effective on Class B and Class C fires.
Sodium Bicarbonate
Dry-Chemical Extinguishing Agent: What agent is twice as effective as carbon dioxide for Class B Fires?
Sodium Bicarbonate
Dry-Chemical Extinguishing Agent: Also known as purple-k, has properties and applications similar to Sodium Bicarbonate
Potassium Bicarbonate.
Dry-Chemical Extinguishing Agent: This agent can extinguish a fire twice the size of Sodium Bicarbonate
Potassium Bicarbonate
Dry-Chemical Extinguishing Agent: Also known as multipurpose dry-chem (pale yellow in color), and is effective on class A, B, And C Fires.
Monoammonium Phosphate
Inert gas that is compressed and used to force extinguishing agents from a portable fire extinguisher; nitrogen is a commonly used one.
Expellant Gas
Dry-Chem Extinguisher Storage Container range from:
Some hold as much as:
30-100 pounds.
2,000 poounds.
Dry-Chem Extinguishers must be located in an area that maintains of temperature range of:
-40F - 120F
Extinguishing agents for combustible metals, also known as _____ _____, are designed to extinguish Class D fires.
Dry Powders
Dry Powder: Sodium Carbonate-based agent with additives to enhance its flow; Designed specifically for use on sodium, potassium, and sodium-potassium alloy fires.
NA-X
Dry Powder: Not suitable for use on magnesium fires
NA-X
Dry Powder: The agent forms an encasing crust or cake on the burning material, which causes and oxygen deficiency
NA-X, MET-L-X
Dry Powder: Listed under UL for use on burning materials at fuel temperatures up to:
1,400F
Dry Powder: Sodium Chloride based agent intended for use on magnesium, sodium, and potassium fires.
MET-L-X
Dry Powder: Applied initially to control the fire, then more slowly to bury the fuel in a layer of the powder
MET-L-X
Dry Powder: Graphite-based agent that extinguishes fires by conducting heat away from the fuel after a layer of the powder has been applied to the fuel.
LITH-X
A _____-_____ system is most effective on fires in commercial cooking equipment that produce grease-laden vapors.
Wet-Chemical
_____ agents are in a general category of fire extinguishing agents that effectively leave no residue.
Clean Agents
_____ agents are effective on Class A, B, and C fires and will not conduct electricity.
Clean Agents
One of the first groups of clean agents developed. Effective on Class B and C Fires
Halon Agents
