Carbon Dioxide (CO2) Fire Suppression Agent:

Carbon dioxide is most effective on Class B and Class C fires and has non-conductive properties, so it can be used on electrical (anything plugged in) fires and is residue-free and will not cause corrosive destruction to electrical equipment. Carbon dioxide (CO2) is an effective discharge agent in fire extinguishers for several reasons:

  1. Smothering: Carbon dioxide is a heavy gas that can displace the oxygen that fuels the fire, effectively smothering the flames.
  2. Non-Conductive: Carbon dioxide is a non-conductive gas, which makes it safe to use on electrical fires without creating a risk of electrical shock.
  3. Clean: Carbon dioxide leaves no residue after it is discharged, making it a clean and safe choice for fire suppression.
  4. Safe for People: Unlike some other fire suppression agents, carbon dioxide is safe for people and does not cause harm if it is inhaled in small quantities.
  5. Versatile: Carbon dioxide is effective on a wide range of fire types, including Class B fires (flammable liquids and gases) and Class C fires (electrical equipment).
  6. Effective Cooling: The high pressure discharge of carbon dioxide helps to cool the surrounding area and prevent re-ignition of the fire.
  7. Environmentally Friendly: Carbon dioxide is a naturally occurring gas and is not harmful to the environment, making it a preferred choice for fire suppression in many industries.

Carbon dioxide is a highly effective fire suppression agent because it is fast-acting, safe for people, versatile, and leaves no residue after it is discharged.

US Coast Guard (USCG) Approved:

United States Coast Guard (USCG) approved fire extinguishers are specialized fire suppression devices that meet the stringent standards set by the USCG for use on boats, ships, and other marine vessels. These fire extinguishers are designed to handle fires in a marine environment, where standard fire extinguishers may not be suitable.

USCG approved fire extinguishers must undergo rigorous testing and certification to ensure they meet the USCG’s specifications for performance, reliability, and durability. The USCG requires that these fire extinguishers are able to quickly and effectively suppress fires in a marine setting, including fires involving flammable liquids, electrical equipment, and cooking equipment.

In addition to meeting the USCG’s performance standards, these fire extinguishers must also be designed with safety and ease of use in mind. They must have clearly marked labels and instructions, and be equipped with appropriate mounting brackets for secure installation on a vessel.

USCG approved fire extinguishers play a critical role in ensuring the safety of marine vessels and their crew by providing reliable fire protection in the event of an emergency.

T-Handle Brass Valve

The T-handle brass valve is a simple but effective mechanism for controlling the flow of carbon dioxide gas from a fire extinguisher. It is an important safety feature that can help prevent fires from spreading and causing further damage.

It is commonly found on carbon dioxide (CO2) fire extinguishers, which are used to extinguish fires involving electrical equipment and other types of flammable liquids.

The T-handle brass valve works by controlling the flow of the carbon dioxide gas from the extinguisher. When the T-handle is pulled, it releases the pressurized carbon dioxide gas from the cylinder, which then flows through the discharge hose and out the nozzle or horn of the extinguisher.

The brass valve on a CO2 extinguisher has two positions: open and closed. When the T-handle is in the closed position, the valve is shut and no gas can escape. When the T-handle is pulled, the valve opens and the gas is released.

It is important to note that once a CO2 extinguisher has been discharged, the valve cannot be closed again. This is because the pressure inside the cylinder drops significantly when the gas is released, making it difficult or impossible to reseal the valve.

UL Rating 20B:C

The UL rating system is used to indicate the fire-extinguishing capabilities of a portable fire extinguisher. This rating is assigned by Underwriters Laboratories (UL), an independent organization that tests and certifies products for safety.

The 20B:C rating indicates that the fire extinguisher can be used to extinguish fires involving Class B and Class C fires. Class B fires involve flammable liquids and gases, such as gasoline, oil, and propane. Class C fires involve electrical equipment, such as appliances, wiring, and circuit breakers.

The number 20 before the letter B indicates the capacity of the extinguisher to put out a Class B fire, which is measured in square feet. A 20B-rated extinguisher is capable of extinguishing a fire that involves a flammable liquid or gas that covers an area of up to 20 square feet.

The letter C after the number 20 indicates that the extinguisher can be used on Class C fires. Class C fires are energized electrical fires, so a C-rated extinguisher is required to extinguish them safely.

Typical Applications for UL 20B:C Rated Wheeled Fire Extinguishers

The UL Rating 20B:C indicates that the fire extinguisher is suitable for use in a variety of settings, including homes, businesses, and industrial facilities. It is important to select the appropriate fire extinguisher based on the type of fire that may occur, and to ensure that it is properly maintained and easily accessible in case of an emergency.

UL Rating 20B:C fire extinguishers are commonly found in a variety of settings, including homes, offices, retail stores, and industrial facilities.

In homes, a 20B:C fire extinguisher can be useful in kitchens, garages, and workshops, where flammable liquids and gases may be present.

In offices and retail stores, 20B:C extinguishers are often installed near electrical equipment, such as computers, printers, and copiers, to protect against Class C fires that may occur.

In industrial facilities, such as manufacturing plants and chemical processing plants, 20B:C extinguishers may be used to protect against fires involving flammable liquids and gases that are commonly used in these settings.
