It depends on the quantity. If you have a great load, yes. If you have a little, no. Some Class D "dry powder" extinguishers use salt (NaCl) as one component.
no it can notit will onliy mack it flam more and sparck will come up so no you can not
NO, use salt! Unless its a grease fire only use water as a last resort (ie you have no salt and cant blow it out) NEVER USE WATER ON A GREASE FIRE!!!!!!!!!!!!!!
No, that would be very dangerous.
Yes, a fire extinguisher works on a grease fire. What you have to avoid with grease fires is throwing water on them, because the burning grease will just float on the water and will be splashed around as the water heats and vaporizes, spreading the fire, rather than being put out. But the carbon dioxide based fire extinguisher doesn't have that problem.
Well the worst way to put out a GREASE fire is to put water on it.
If it is a grease fire, you need to smother it. You can use generous amounts of salt or baking soda. You can also use the lid to the pan, if it fits tightly.
Flour will burn. The best option is salt.
water
You never use water to put out a fat fire, because the pouring water on burning grease or oil will not extinguish the fire. It will only cause the burning oil to splash, spreading the grease fire around.
Do not use butter to put out a fire, any fire, ever. Butter will add fuel to any fire. If you are near butter, you should be near salt. Salt will put out a small fire.
Grease & Electrical
Grease doesn't contain salt; the salt is added if necessary.
if you ge grease on or near a fire and it could ignite. you can't put a grease fire out with water. but baking soda works
