The editor explains how to use the HFC-227ea fire extinguishing system.

(I) Before HFC-227ea spraying, all personnel must evacuate the fire scene within the delay period (usually 30 seconds). The protection area after the fire is extinguished should be ventilated. Underground protection areas and ground protection areas without windows or with fixed window sashes should be equipped with mechanical exhaust devices. The exhaust vents should be located at the bottom of the protection area and should be directly connected to the outdoors. The ventilation frequency of communication rooms, computer rooms and other places should be no less than five times per hour.

(II) The protection area should meet the following requirements: the ambient temperature should not be too extreme and should be kept dry and well ventilated; the air should not contain explosive, conductive dust and harmful substances such as corrosive components, otherwise it must be protected, and the HFC-227ea fire extinguishing equipment should not be subjected to vibration and impact.

(III) The door of the protection area should be opened in the direction of evacuation and can be closed automatically. The door used for evacuation must be able to be opened from the protection area.

(IV) Personnel who install and debug the equipment should be familiar with the basic structure, working principle, performance and operation procedures of this system, as well as the basic structure and working status of each valve.

(V) Heptafluoropropane gas cylinders should be kept away from heat sources. During transportation, they should be loaded and unloaded with care and collision is strictly prohibited. Heptafluoropropane fire extinguishing devices are different from ordinary fire extinguishing devices and fire extinguishing systems. They must be maintained and inspected by specialized personnel. As one of the commonly used fire extinguishing devices on the market, the sealing of the device must be ensured to ensure its reliability to the greatest extent. Inspection and maintenance personnel must keep relevant records, strictly implement the periodic inspection system, and test relevant performance and parameters to ensure the normal operation of the system.
