What are the proper usage methods and contraindications for flame-retardant felt?

　　A fire blanket is a tool used to extinguish fires. It works by covering burning objects and cutting off the supply of oxygen, thereby putting out the fire. A flame-retardant blanket is a type of blanket that is not easily ignited. These blankets come in various sizes, but for ease of access, fire blankets with side lengths ranging from 1.2 m to 1.8 m are commonly used. Flame-retardant felt It is suitable for extinguishing small fires and preventing them from escalating into major blazes, making it an effective fire-prevention device. It is typically placed in kitchens or laboratories.

　　Previously, flame-retardant felt was mainly made from fireproof fabric; nowadays, most of it is made from fiberglass instead. Since fiberglass itself is inherently difficult to ignite, resistant to burning, and provides excellent thermal insulation, it has become an ideal material for manufacturing flame-retardant felt. Flame-retardant felt is effective at extinguishing small fires and preventing them from escalating into full-blown conflagrations, making it suitable as a fire-prevention device that can be placed in kitchens or laboratories. In the event of an out-of-control fire or a severe blaze, although a fire blanket may not be able to effectively contain the fire, it can still be worn to protect against burns when escaping from the blaze.

　　1. Where is it appropriate to place flame-retardant felt?

　　4. When a fire blanket is used to cover a burning object, fire-extinguishing measures should be taken until the burning object is completely extinguished.

　　II. What are the methods for using flame-retardant felt?

　　1. Industrial Safety: Sparks frequently occur in steel mills, during electric welding operations, in boiler rooms, and other similar environments. Such sparks can easily ignite fires, so flame-retardant felt is essential in these settings. It can effectively resist sparks and welding spatter, thereby separating work areas and eliminating fire hazards caused by welding activities.

　　2. Earthquake Escape: Fold the fire blanket and place it over your head. The flame-retardant felt is elastic and can help cushion the impact of falling debris, making it ideal for earthquake escape.

　　3. Initial Fire Suppression: In the early stages of a fire, you can drape the fire blanket over the ignition source or burning material to quickly extinguish the fire in a short period of time.

　　4. Fire Escape Route: Wrap your body with fire-retardant felt, put on a smoke mask, and quickly evacuate the fire scene. The flame-retardant felt can effectively isolate you from the flames, reduce the intense heat of the fire, and help prevent bodily injury.

　　5. How to fold a fire blanket: Hold the pull straps of the fire blanket with both hands, then lay the blanket flat. Use tape to fold the back side of the blanket over onto the taped side twice, and then fold the left-hand pull strap over to the right side.

　　III. Instructions for Use and Storage of Flame-Retardant Felt

　　1. It’s recommended to keep the flame-retardant felt in a prominent, easily accessible spot at home. In case of a fire, you’ll be able to grab it quickly.

　　2. If the flame-retardant felt is undamaged after firefighting, it can be reused.

　　3. If the flame-retardant felt is damaged after fire extinguishing, Flame-retardant felt After cooling, it can be rolled up and disposed of as non-combustible waste.
