Fire Extinguishers

Water and carbon dioxide fire extinguishers are ineffective on alkali metal fires because they can react violently with alkali metals, such as sodium or potassium, and actually make the fire worse. It is recommended to use a Class D fire extinguisher specifically designed for metal fires in this case.

A hydrocarbon fire extinguisher is a type of fire extinguisher specifically designed to combat fires fueled by flammable liquids such as gasoline, oils, and grease. These extinguishers contain agents like dry powder or foam that work by smothering the fire and cutting off the oxygen supply to extinguish the flames.

In short, No - in the UK "Class 1" is a form of performance that indicates how easily something burns ('Class 4" being the worst).

Fire resistance on the other hand is a term that relates to a construction's ability to resist the passage of fire (e.g. a wall, floor, door etc).

The fact that a material is "Class 1" doesn't necessarily have any bearing on its fire resistance performance. For example, PVC cladding can be obtained to a 'Class 1' rating, but it wouldn't contribute much to the wall's fire resistance performance at all.

A person's hair fire should be smothered by using a heavy material like a coat or a blanket, or by using a fire extinguisher if available. If a person's clothing is on fire, they should stop, drop to the ground, cover their face, and roll to smother the flames.

If you have plenty of crank, but, no, fire, then your problem is in the fuel system. Check your fuel pump by disconnecting the lower fuel line on the filter and then try starting the car. If no fuel comes out of the line, you have found your problem! Bad fuel pump!

Yes.

Firefighting foam is normally used in diluted form - 1-6% foam and 94-99% water, depending on the application. This reduces its corrosive effects, but the pure agent can be quite damaging to equipment over time.

Eg: On the Antarctic FD (Mcmurdo Station, Antarctica) we bought 4 new air rescue firefighting vehicles in 2005 which we filled with a non-freezing undiluted foam/antifreeze mix. When we attempted to use the vehicles for the first time in 2007, the brass fittings on the foam lines blew apart in several places as soon as they were charged, rendering the truck useless. This was due to corrosion by the foam agent, which had leaked past the check valves and filled the foam lines for an extended time.

I don't know what chemical is in wasp killer if that is what you are asking. I know that diatomaceous earth works well on nests that are in the ground. The wasps cannot get through it without dying.
There is a safer wasp killing spray. I think it is Concern brand.

Monex Dry Powder is a precious metal powder used for investment purposes or in the production of various industrial products. It is produced through a unique refining process that results in a high-purity form of the metal. Investors often purchase Monex Dry Powder as a way to diversify their portfolios and hedge against economic uncertainties.

Anything that will cool the fire below kindling point, or exclude oxygen from the fire.

Homo erectus was the first to use fire. It took millions of years to discover fire. It was discovered when lightning burnt something. The people from the homo erectus clans then started making it with sticks and stones looking out for little sparks. This technique is still used today by some people and others use our improved technology.Like Handy Man, hominids in the Upright Man group were toolmakers. But with their larger brains,they were able to invent more complex tools, including strong hand-axes made of stone. Upright Man's greatest advantage was the ability to use fire. Anthropologists have found burned animal bones in the same places as Upright Man remains. This clue means that Upright Man probably used fire to cook animal meat.Scientists aren't sure whether these hominids were hunters or wheher they found dead animals to eat.

You must pull the trigger every time you want to fire a round. That’s why it’s called semi - automatic

No, using the empty extinguisher is necessary in order to progress through the game. It is used to obtain the full extinguisher by combining it with the fire hose nozzle.

Carbon dioxide fire extinguishers are not recommended for calcium carbide fires because calcium carbide reacts violently with water, producing acetylene gas. When a carbon dioxide extinguisher is used, it can displace oxygen and potentially build up the concentration of acetylene gas, which can lead to a more hazardous situation. It is safer to use dry powder extinguishers or other specialized extinguishing agents for calcium carbide fires.

If V1 = V2 => p1 / T1 = p2 / T2 <=> p2 = p1 * T2 / T1

Let's assume that T1 = 20 C Degree = 313 K

=> p2 = p1 * 343/313 => p2 = 1.10 p1 which means 10% higher pressure.

In MegaMan Battle Network 6, you can find the fire extinguisher in ACDC Town. Go to the SciLab area and enter Dex's house. Inside Dex's house, go up the stairs and you will find the fire extinguisher in the room on the top left.

The exact number of portable hand held fire extinguishers located in the cargo compartment of a USAF C-17 may vary depending on the specific configuration and mission requirements of the aircraft. However, typically there are multiple fire extinguishers strategically placed throughout the cargo compartment to ensure adequate fire suppression capabilities in case of emergency situations.

You should use a fire extinguisher when a fire is small and contained, such as a small grease fire on a stove or a trash bin fire. It is important to remember that you should only attempt to use a fire extinguisher if you have been trained in its proper use and if it is safe to do so. If the fire is large or spreading quickly, evacuate and call emergency services.

The white stuff in fire extinguishers is typically a chemical called dry chemical powder or monoammonium phosphate. This powder is a fire suppression agent that is effective for extinguishing different types of fires, such as those involving flammable liquids, gases, and electrical equipment. When released, the powder smothers the fire and helps to cool the fuel, preventing it from reigniting.

If you remove the siphon tube from a CO2 fire extinguisher, the extinguisher will not work properly. The siphon tube is responsible for drawing and releasing the CO2 gas from the extinguisher. Without it, the CO2 gas will not be able to flow out effectively, rendering the extinguisher ineffective in suppressing fires.

Water is good as it will cut off oxygen and cool the heat source.

Powder and foam will smother to cut off oxygen.

Carbon Dioxide (CO2) will cut off oxygen but blast of gas may spread ther fire by blowing light material such as paper causing it to set fire to other things.

Don't use water on oil, or a chip pan fire.

A Class C fire extinguisher.
