Fire shutter door http://wangsjgcw.gongchang/ Normally closed fire doors are not meant to be opened frequently. These doors play a critical role in fire safety, as they help prevent the spread of smoke and heat during a fire. Fire evacuation routes must never be blocked or occupied with any items, as they serve as the lifeline for people to escape safely.
It's important to understand that normally closed fire doors should remain shut at all times, though they are not locked. This is a common misconception among many people, who often leave them open without realizing the potential danger. When left open, these doors lose their effectiveness in containing fires and protecting lives.
A properly functioning normally closed fire door can significantly slow down the spread of smoke and toxic gases, giving people more time to evacuate safely. In case of a fire, it’s crucial that these doors are always closed, while normally open fire doors should be able to close automatically when needed. Additionally, all emergency exits and evacuation routes must be clearly marked and kept free from obstructions.
Fire doors come in various types, including wooden fire doors, steel fire doors, and fire shutter doors. Choosing the right type depends on the specific requirements of the building and local fire safety regulations.
