What else can I help you with?
What type of foam do you use on polar solvents?
Fluorocarbon-based or fluorinated foams are typically used for combating polar solvents due to their resistance to those types of chemicals. These foams form a protective barrier on the surface of the solvent, preventing ignition or further spread of the fire.
Do you use CO2 to extinguish Liquid Fire?
The CO2 or the dry Chemicals can be used to extinguish Liquid Fire, though other extinguishes can be used like halogen extinguishers, BUT the halogen is doesn't help as much as it harms, because it causes a toxic gas, and there is Foam extinguishers they come handy too.
Is heat fuel or oxygen removed when you put out a forest fire?
Heat is not removed when putting out a fire; instead, the removal of fuel or oxygen is what helps extinguish the flames. Methods like water, foam, or dirt can suffocate the fire by removing oxygen, while firebreaks or controlled burns can remove fuel to contain or stop the fire's spread.
While working to extinguish a wild land fire how would you exclude the oxygen reduce the heat and remove the fuel?
To exclude oxygen, firefighters can create firebreaks or use water to smother the fire. To reduce heat, they can use water, foam, or fire retardants to cool the flames. Removing fuel involves clearing vegetation or creating a backburn to consume the fuel ahead of the main fire.
Why washing soda not used to extinguish fire?
Washing soda (sodium carbonate) is not typically used to extinguish fires because it does not have the same cooling or smothering effect as substances like water, foam, or carbon dioxide. While it can help control certain types of fires by inhibiting combustion reactions, it is not as effective as other fire extinguishing agents. Additionally, using washing soda could potentially create its own set of safety hazards when dealing with fires.
How will you extinguish fire?
by foam extinguisher
What propety of foam allows it to extinguish fire?
Most are water based, with a thickening power to make it heavier, the purpose of foam, in a firefighting use is to smother and deprive the fire of oxygen
Where is a labs fire extinguisher located?
Laboratory fire extinguishers shoud be located just inside each exterior door. To be as safe as possible they should probably be of the type AR-AFFF, that is Alcohol Resistant Aqueous Film Forming Foam. While these foam extinguishers are messy they extinguish the fire AND THEN they provide reflash protection. Other extinguishing agents will extinguish the fire but if all the elements of a fire are still there, oxygen fuel and temperature, then the fire can reignite. AR-AFFF prevents that and prevents the foam from degrading due to solvents which tend to be present in Laboratories.
What type of foam do you use on polar solvents?
Fluorocarbon-based or fluorinated foams are typically used for combating polar solvents due to their resistance to those types of chemicals. These foams form a protective barrier on the surface of the solvent, preventing ignition or further spread of the fire.
How does one extinguish a paraffin fire.?
To extinguish a paraffin fire, you can use a Class B fire extinguisher specifically designed for flammable liquids or smother the fire by covering it with a damp cloth or a fire blanket. Avoid using water, as it can spread the fire due to the oil content in paraffin. Shut off the source of the fuel if possible.
What are solute and solvent in foam?
In foam, air is typically the solute and the liquid or solid that surrounds the air bubbles is the solvent. The solvent helps stabilize the foam structure by forming a film around the air bubbles that prevents them from coalescing.
Do you use CO2 to extinguish Liquid Fire?
The CO2 or the dry Chemicals can be used to extinguish Liquid Fire, though other extinguishes can be used like halogen extinguishers, BUT the halogen is doesn't help as much as it harms, because it causes a toxic gas, and there is Foam extinguishers they come handy too.
Why would you use foam to put out a fire?
Not normal foam but carbon dioxide foam from a fire extinguisher. This special foam covers the fire and takes all the oxygen out of it, and with no oxygen, no fire!!!
What is the most effective method for extinguishing an oil fire?
The most effective method for extinguishing an oil fire is to smother it by cutting off its oxygen supply. This can be done by covering the fire with a fire blanket, sand, or a specialized foam designed for oil fires. Water should not be used to extinguish an oil fire as it can cause the fire to spread.
What do you call the substance that takes in or dissolves or takes in the solute?
The substance that takes in or dissolves the solute is called the solvent.
Where would you use a foam fire extinguisher?
"foam" fire extinguishers are made for hydrocarbon fires...i.e: gasoline, diesel, etc. These fires are considered class "b" (flammable liquids), and are mostly used by professionals and in commercial and industrial settings. These extinguishers are charged with anther AFFF, FFFP, or AR-AFFF, however, these class of extinguishers are only rated class A & B fires and are hazardous to the environment, humans and animals in addition to being very corrosive.
What is the best glue for polystyrene foam?
The best glue for polystyrene foam is a solvent-based adhesive specifically designed for bonding foam materials.
