Trolley-type CO₂ fire extinguishers are larger variants of portable CO₂ fire extinguishers, designed for more extensive fire protection needs in industrial or commercial settings. Here are some key features and considerations regarding trolley-type CO₂ fire extinguishers:
Size and Capacity: Trolley-type CO₂ extinguishers are significantly larger than portable ones and are mounted on wheeled trolleys for easy mobility. They typically have larger CO₂ cylinders, providing greater firefighting capacity.
High-Pressure Cylinder: Like portable CO₂ extinguishers, trolley-type extinguishers contain compressed CO₂ gas stored in a high-pressure cylinder.
Discharge Mechanism: These extinguishers feature a discharge mechanism, usually activated by pulling a lever or releasing a safety pin, similar to portable CO₂ extinguishers.
Mobility: The trolley design allows for easy transportation of the extinguisher to the location of the fire. This mobility is particularly useful in large industrial facilities or warehouses where fires may occur at different locations.
Versatility: Trolley-type CO₂ extinguishers are effective against Class B (flammable liquids) and Class C (electrical) fires, making them versatile options for a range of fire hazards.
Multiple Nozzles: Some trolley-type extinguishers may have multiple discharge nozzles, allowing for more efficient coverage of a larger area or multiple fire points.
Increased Discharge Duration: Due to their larger size and capacity, trolley-type CO₂ extinguishers typically provide a longer discharge duration compared to portable extinguishers. This extended discharge time can be crucial when dealing with larger or more persistent fires.
Training and Maintenance: Proper training in the use of trolley-type CO₂ extinguishers is essential for effective firefighting. Additionally, regular maintenance and inspection are necessary to ensure the extinguisher is in proper working condition when needed.
Safety Considerations: When using trolley-type CO₂ extinguishers, it's essential to follow safety protocols, including maintaining a safe distance from the fire, wearing appropriate protective gear, and ensuring proper ventilation in the area.
Trolley-type CO₂ fire extinguishers are valuable firefighting assets in environments where larger fire hazards are present, providing reliable and effective suppression capabilities to protect life and property.
