FM200 (HFC-227ea) Clean Agent, as an efficient fire extinguishing agent specially designed for high-risk scenarios such as oil depots, has become an upgraded alternative to traditional carbon dioxide (CO₂) fire extinguishing agents with its unique chemical suppression mechanism and safety features. Compared with CO₂, its core advantages directly address the pain points of oil depot fire protection:
Advantages of fire extinguishing speed and concentration: The FM200 Clean Agent only requires a concentration of 9-10% to extinguish Class B (oil) and Class E (electrical) fires within 8 seconds, while CO₂ needs to reach a concentration of more than 34%. The latter is not only difficult to quickly reach an effective fire-extinguishing concentration in the enclosed space of the oil depot, There is also a risk of suffocation for on-site operators due to oxygen deficiency.
Upgraded anti-reignition capability: FM200 Clean Agent achieves fire extinguishing by interrupting the combustion chain reaction. The agent molecules can be adsorbed on the oil surface to form a microfilm layer that inhibits evaporation and reduces the probability of reignition. CO₂ extinguishes fire only through physical suffocation. If the oil surface temperature does not drop below the ignition point, it is prone to secondary combustion due to environmental disturbance. The simulation test of an oil depot shows that the re-ignition rate of oil tank fires protected by FM200 Clean Agent is 0, while the re-ignition rate after CO₂ fire extinguishing is as high as 27%.
Electrical equipment compatibility: The insulation resistance of FM200 Clean Agent is > 10¹²Ω. It can extinguess fires of electrical equipment such as pump groups and metering instruments in oil depots under energized conditions, avoiding the loss of control of oil tank liquid levels caused by power failure. The low temperature (-78.5℃) during CO₂ discharge may cause "cold shock" faults in the equipment, such as embrittlement of the sealing ring of the solenoid valve and malfunction of the pressure sensor.

Application:

Deep protection of the oil storage tank area
In areas such as crude oil storage tanks and gasoline tanks, the FM200 Clean Agent adopts a fixed top-spray fire extinguishing system to precisely target the fire risks caused by the evaporation of oil vapor:
A circular nozzle array is installed on the top of each storage tank and is linked with the liquid level monitoring system through a flame detector. When the oil and gas concentration in the tank exceeds 30% of the lower explosive limit (LEL) or an abnormal temperature rise occurs, the FM200 Clean Agent system is automatically activated and a total flooding fire extinguishing concentration is formed within 10 seconds. Suppress the combustion of the oil surface while preventing the explosion of the tank. The case of a 50,000-cubic-meter storage tank of a certain petrochemical enterprise shows that the system successfully intercepted the tank top fire caused by lightning strike, avoiding nearly 100 million yuan in tank damage losses.
Compared with the CO₂ system which requires continuous discharge for 30 minutes to maintain the concentration, the FM200 Clean Agent only needs a single discharge to lock in the fire, reducing the dosage of the agent by 60% and lowering the number of cylinder configurations and installation costs.

2. Emergency response for the oil pump room and distribution room
The motors in the oil pump room of the oil depot, the transformers in the distribution room and other equipment are high-risk points for electrical fires. The pipeless device of the FM200 fire suppression system shows flexible advantages:
Miniature FM200 Automatic Fire Extinguisher is embedded in the oil pump motor control cabinet. The winding temperature is monitored in real time by a temperature sensor. When the temperature exceeds 130 ° C (ignition point of insulating material), the cylinder automatically breaks the film and sprays the agent to extinguish the fire caused by the initial electric spark within 3 seconds. Prevent the fire from spreading to the nearby oil pipe. The measured data of a certain oil depot shows that this scheme has shortened the average fire response time from 18 seconds of the traditional CO₂ system to 5 seconds.
The distribution room is equipped with a cabinet-type FM200 gas fire extinguishing system, which has a volume of only 1.2 cubic meters (the CO₂ system requires 2.5 cubic meters for the same protected area). It can be installed in narrow Spaces and supports interconnection with the SCADA system. When extinguishing a fire, it automatically cuts off non-fire power supplies and simultaneously sends alarm coordinates to the central control room, with a positioning error of less than 1 meter.

3. Protection of the loading platform and oil pipelines
FM200 Automatic Fire Extinguisher 's mobile fire extinguishing unit provides flexible protection in open-air Settings such as vehicle loading platforms and valve Wells of oil pipelines:
The loading platform is equipped with a liftable FM200 Clean Agent injection device. When the static electricity of the vehicle causes oil leakage and fire, the operator triggers the injection through the handheld terminal. The agent forms an air curtain with a diameter of 5 meters to cover the fire source and prevent the fire from spreading to the oil storage area. A case of a certain finished oil depot shows that the device extinguished the gasoline splashing fire during the loading process within 5 seconds, avoiding a chain explosion accident.
Corrosion-resistant FM200 gas cylinders are installed in the underground valve Wells of the oil pipeline. The pressure-sensing start-up method is adopted. When the pipeline rupture causes the accumulation of oil and gas in the well and reaches the explosion conditions, the chemical agent is automatically discharged to reduce the oxygen concentration to a safe range and prevent deexplosion from causing damage to the pipeline structure.
