Water Mist (WM) Fire Extinguisher: #
- Usage: Suitable for Class A, B, and F fires.
- Mechanism: Water mist extinguishers discharge a fine mist of deionized water droplets. When the mist comes into contact with the fire, it evaporates rapidly, reducing the heat and suffocating the flames.
- Benefits:
- Effective on various types of fires, including solid materials (Class A), flammable liquids (Class B), and cooking oils/fats (Class F).
- The mist cools down the fire and prevents re-ignition.
- Non-toxic and safe to use in enclosed or sensitive environments.
Water Mist (WC) Fire Extinguisher: #
- Usage: Suitable for Class A fires.
- Mechanism: Water mist extinguishers operate similarly to water mist extinguishers. They discharge a mist of deionized water droplets to cool down the fire and suppress flames.
- Benefits:
- Specifically designed for Class A fires involving solid materials like wood, paper, and textiles.
- It can be used in areas where traditional water-based extinguishers may cause damage to sensitive equipment or materials.
- Provides effective fire suppression without leaving a residue.
Key Difference: #
- Targeted Fire Classes: The main difference between WC and WM fire extinguishers lies in the specific fire classes they are designed to tackle. WC extinguishers are primarily intended for Class A fires, while WM extinguishers are versatile and can be used on Class A, B, and F fires.
- Versatility: WM extinguishers offer broader application due to their effectiveness on multiple fire classes, making them a more versatile option for environments with varied fire risks.
- Specialised Use: WC extinguishers are tailored for combating solid material fires (Class A), providing focused protection in settings where this type of fire hazard is prevalent.
Understanding the distinctions between these two types of water mist fire extinguishers allows users to select the most suitable option based on their specific fire safety requirements and potential environmental risks.
