ABC Dry Powder for Fire Extinguishers

ABC Dry Powder Fire Extinguishers utilize mono ammonium phosphate-based dry chemical powders, designed for multipurpose use on Class A, B, and C fires. Available in concentrations of 40% and 90%, these extinguishing agents are SABS approved, ensuring reliability and effectiveness.

Applications:

Class A Fires:
The dry chemical powder insulates Class A fires by melting at approximately 350�400 degrees Fahrenheit. Class A fires typically involve common combustible materials such as wood, paper, or trash.

Class B Fires:
For Class B fires, the powder effectively interrupts the chain reaction by forming a coating on the burning surface. Class B fires involve flammable liquids or gases, including gasoline, oil, propane, and natural gas.

Class C Fires:
ABC dry powder is safe and effective for Class C fires, as it is a non-conductor of electricity. Class C fires typically involve live electrical equipment, which requires extinguishing agents that do not conduct electricity, unlike water. It's important to note that electricity can also cause Class A and B fires.

Inappropriate Uses:

ABC dry chemical powder should not be used on chlorine or oxidizer fires, as the resulting chemical reaction can lead to explosions or the release of toxic gases. Water is recommended for these situations. Additionally, it is ineffective for certain metal fires (Class D) and cooking oil fires (Class K). Due to the corrosive nature of ABC dry chemical powder, it is not advisable to use it around aircraft or sensitive equipment.
