Dry chemical powder agent is known for its versatility in fire extinguishing operations. As most of the modern spaces have live electrical circuits running everywhere, using conventional agents like water is not safe because it can act as a conductive medium for fire propagation. For factory, warehouse, or commercial space owners, it is important to know which dry chemical powder type is suitable for their space. Selecting the right formulation helps them deal with fire accidents effectively in their respective space.
Importance of Moisture Resistance and Flowability
Dry powder chemicals should remain in a state that can flow freely so that they can be discharged easily. But once they get into contact with any moisture, it can lead to their solidification and make them inaccessible for use. Dry chemical powder blends are mixed in such a way, with specialized agents that make it impossible for moisture to be absorbed and increases their flow properties. The great benefits of these characteristics are that it maintains the powder in the right condition.
Flamax Dry Chemical Powder Variants
Flamax is a series of dry chemical powders by Foamtech Antifire Company. These are the key applications of each variant:
- For Multiple Fire Risks
The ABC dry chemical powder type is effective against Class A, Class B, and Class C fires affecting materials like wood, paper, plastic, flammable liquids, gases, and electrical devices. The dry chemical consists of monoammonium phosphate mixed with fillers for more fluidity, moisture resistance, and stability. ABC dry chemical can be used in petroleum refineries, chemical plants, warehouses, and airports where a combination of different types of fires must be dealt with.
- For Liquid and Gas Fires
BC dry chemical powder is made to fight fire hazards due to flammable liquids, gases, and energized electrical devices. The product consists of sodium bicarbonate and potassium bicarbonate formulations suitable for areas exposed to flammable liquids and gases. The filler formulation allows higher flowability and moisture resistance during discharge.
- For High-Risk Applications
UPBC is a dry chemical powder based on potassium bicarbonate and urea, which can be used for flammable liquids, gases, and electrically charged items. Its flow properties are impressive, as well as its resistance to moisture, insulation, and discharge properties.
- For Combustible Metal Fires
When combustible metals like magnesium, sodium, potassium, and lithium experience flames, a special powder must be used to extinguish the fire. Water reacts dangerously with certain metal flames.
TEC Class D fire extinguisher forms a protective barrier over the metal that is burning, thereby reducing its exposure to oxygen and absorbing heat. It is used in industries that handle metals.
- For Metal and Pyrophoric Fires
Metal alkyls and pyrophoric materials ignite spontaneously and can catch fire if they are exposed to water or even the air. PYROEX is effective against fires involving metals, metal alkyls, and pyrophoric materials. It suppresses the fire by absorbing heat and creating a blanket of fire. The product is used in highly specialized operations using magnesium turnings and triethyl aluminium.
Conclusion
The right choice should always begin with the fuel being burnt, the class of fire, and the conditions of both storage and use. Choosing a formulation that is suitable for the hazard will result in a better fire protection choice in industry. A single dry chemical powder type will not work on every kind of fire hazard. Therefore, it is important to know the classification and suitable application type.
