A magnisium fire burns at a significantly higher temperature than a typical fire with other combustable materials. If a water extinguisher were to be used on a metal fire, the heat of the fire will cause the water to break down into its chemical constituants Hydrogen, and Oxygen (H2O), and instead of removing heat from the fire it will actually cause the fire to intensify due to the addition of fuel Hydrogen (H2) and an oxidizer Oxygen (O).
Other extinguishers can extinguish the fire, but again due to the extreme heat it will take significantly more agent to extinguish this type of fire than would be needed for a standard combustables fire. An extinguishing agent which is designed for use on a metal fire can withstand the extreme heat and will extinguish the fire by blanketing the burning metal and smothering the fire by depriving it of oxygen. Dry Sand for example would work well. There are other agents which could be used on this type of fire which extinguish the fire interfering with the fire's chemical reaction rather than smothering it.
What else can I help you with?
Can magnesium chloride react with sodium bicarbonate?
Yes, magnesium chloride can react with sodium bicarbonate to produce magnesium carbonate, water, and carbon dioxide gas. This chemical reaction is commonly used in certain types of fire extinguishers.
What types of fire are ABC fire extinguishers designed to extinguish?
Ordinary combustibles, such as wood, cloth, paper, burning liquids such as gasoline, and fires in live electrical equipment. They are not for deep fat fryers (class K) nor for combustible metals such as magnesium (Class D fire).
What is the classification of a metal fire extinguisher and how does it differ from other types of fire extinguishers?
A metal fire extinguisher is classified as a Class D extinguisher, specifically designed to put out fires involving combustible metals like magnesium, titanium, and sodium. Unlike other types of fire extinguishers that are effective on different types of fires (such as Class A, B, or C), Class D extinguishers are specifically designed for metal fires and use a dry powder agent to smother the fire and prevent it from reigniting.
Is organic salt a form of extinguisher?
Yes, some types of Class D fire extinguishers use NaCl (table salt) as an extinguishing agent for fires involving magnesium, sodium and potassium.
What is the colour of carbon dioxide extinguishers?
Carbon dioxide extinguishers are typically identified by their black color. This color coding helps distinguish them from other types of fire extinguishers, which may be painted in different colors to indicate their contents. The black color indicates that the extinguisher is designed for use on electrical fires and flammable liquids. Always check the label for specific usage instructions and safety information.
What are fire extinguishers be used for?
FIRE extinguishers are used to put out fire.
Class b fire extinguishers are for what types of fires?
liquids
What types of fire extinguishers are safe to use on electrical type fire?
Extinguishers with a Class C rating (C can be used on Currents)
What is a class d extinguisher used for?
No, hence them being Class D fire extinguishers they are only used on combustible metal fires. there are different class d extinguishers as well for specific metal fires no one class d extinguisher on all metal fires mostly very specific
When and where are fire extinguisher used?
Fire extinguishers are used by businesses, homes and even firefighters to put out small fires. There are different types for use in locations where certain types of fires can occur, such as grease fire in a commercial kitchen, or fuel fire at the gas station or airport. Fire extinguishers can be large and on wheels (or even its own vehicle), or small and hand-carried. You can use a fire extinguisher on a fire but make sure it is used on the right type of fire as directed on extinguisher. One exception is when Magnesium is burning. Large amounts of magnesium on fire should be covered with sand or limestone. Water will not slow it down at all. Even CO2 is not efficient with magnesium as it burns with high temperature and reacts with many things when that hot. Specially prepared Class D fire extinguishers can be used on flaming metal fires, such as magnesium, lithium or titanium -- but you have to have one handy for it to be of any use.
What sort of fire extinguishers should we get if we live in a flat on the 12th floor?
There are several types of fire extinguishers that one should purchase that rely on their compact form and low weight such as Alert 5 Rechargeable fire extinguishers, and Tundra Tundra extinguishers.
Portable fire extinguishers are labeled for what purpose?
to put out fire In other words, because there are different types of fires there are different types of fire extinguishers. The label will tell you what type of fire it is designed for.
