What Do the Symbols on a Fire Extinguisher Indicate?
If you’ve ever glanced at the cylindrical fire safety device in your home, office, or school and pondered its symbols, you’re not alone. These symbols, or pictograms, provide critical information about the type of extinguishers and the kind of fires they are designed to suppress. Each symbol corresponds to a particular class of fire: A, B, C, D, or K, each of which denotes the nature of the flammable materials. These include organic materials, flammable liquids, electrical equipment, metals, cooking oils, and fats.
Occasionally, some symbols are circled by a red slash, warning against using the extinguisher on certain types of fires, as it could potentially exacerbate the situation. These symbols act as a quick guide, enabling you to select the appropriate fire extinguisher during an emergency.
Types of Fire Extinguisher Symbols
Symbols on a fire extinguisher exhibit diverse shapes, colors, and designs. Each serves a purpose in guiding the user on effectively and safely utilizing the device.
What do the Colors Mean?
Fire extinguisher colors are not merely decorative; they denote the type of fire the extinguisher is designed to tackle. For instance, foam extinguishers typically bear a cream label, signaling their utility in extinguishing fires involving flammable liquids.
Importance of Pictograms
Pictograms offer visual guidance for operation, facilitating the usage of the extinguisher during an emergency, even without a common language.
Types of Fire
Fires are classified into different types based on their fuel source, which in turn influences the best extinguishing agent and method for suppressing them.
Class A Fire
Class A fires involve combustibles like wood, paper, and textiles, leaving ashes behind. Water fire extinguishers, identifiable by their red color, are ideal for dealing with these fires.
Class B Fire
Class B fires involving flammable liquids and gases take us into more dangerous terrain.
This category belongs to flammable liquids such as gasoline, oil, and paints. Envision a paint can tip over near an open flame – quite terrifying.
Flammable gases like propane or butane also constitute Class B fires. Notice the caution signs at gas stations? They’re there for a reason!
Class C Fire
Class C fires, involving electrical fires from equipment like computers, pose a unique challenge in our modern era.
Class D Fire
Class D fires involve flammable metals like magnesium and titanium, a rare but intimidating adversary.
Class K Fire
Finally, we have Class K fires. These typically occur in kitchens and involve cooking oils and fats. Wet chemical extinguishers, recognizable by their yellow color, are most effective in tackling these fires.
