What do the normally closed fire doors do not open normally?

Fire Shutter Door – http://wangsjgcw.gongchang/ Normally closed fire doors are not meant to be opened frequently. These doors play a crucial role in fire safety by preventing the spread of smoke and heat, giving people more time to escape safely. It's essential to remember that fire evacuation routes must never be blocked or occupied with any items. These passages are life-saving routes during emergencies. A normally closed fire door should always remain closed but not locked, which is often misunderstood by many. This simple rule can make a big difference in saving lives during a fire. When a fire occurs, these doors act as barriers, slowing down the spread of smoke and toxic gases, thus increasing the chances of survival for those inside. To ensure that fire doors function properly when needed, it's important to keep them in their correct positions. Normally open fire doors should be able to close automatically in case of an emergency. Additionally, all evacuation signs must be clearly visible and properly placed to guide people quickly to safety. Fire doors come in different types, such as wooden fire doors, steel fire doors, and fire shutter doors. Choosing the right type based on your building's needs is essential for optimal fire protection.
