Fire safety is important for every business owner. In the event of a fire, you want to be as prepared as possible. That's why it's important to know all about dry chemical fire extinguishers, including what they're used for, how they work, and how to maintain them properly.
What Are Dry Chemical Fire Extinguishers?
A dry chemical fire extinguisher is a backpack-style or handheld device that uses a fine powder to smother and extinguish fires. The most common type of dry chemical powder is sodium bicarbonate or common household baking soda.
What Type of Fires Are Dry Chemical Fire Extinguishers Used For?
There are different types of fires that can occur, including:
- Class A - wood, paper, and cloth
- Class B - liquids and gases
- Class C - electrical
Each type of fire requires a different type of fire extinguisher. Fortunately, dry chemical fire extinguishers effectively put out all types of fires, including flammable liquids and electrical equipment. This trait has earned it the nickname 'ABC fire extinguisher.'
How Do Dry Chemical Fire Extinguishers Work?
When the canister of a dry chemical fire extinguisher is discharged, the dry chemical powder is released in a stream onto the fire. The powder coats the fire and its fuel, effectively disrupting it by smothering the flame and preventing it from reigniting.
Caution should be used, however, when employing a dry chemical fire extinguisher because the powder can irritate your eyes, nose, throat, and lungs. It can also be harmful if ingested. So be sure to follow the manufacturer's instructions carefully.
How Do You Properly Maintain a Dry Chemical Fire Extinguisher?
It is important to regularly inspect any fire extinguisher and perform required maintenance according to the manufacturer's instructions. Typically, fire extinguisher maintenance involves annual servicing by a certified professional.
You should, however, also test your extinguishers regularly and inspect the pressure gauge to make sure they are in working order. If you need to use your dry chemical fire extinguisher, it is important to have it refilled as soon as possible so that it will be ready in case of another emergency. Most companies that sell dry chemical fire extinguishers will also provide refill services.
Dry chemical fire extinguishers are an important piece of safety equipment for any home. By understanding how they work and regularly maintaining them, you can be sure that they will be ready to use in case of an emergency.
