When using fire doors, please note the following:
1. Fire doors should be kept closed, especially normally closed fire doors.
2. Install automatic door closers to ensure timely closure in case of fire.
3. Regularly check the sensitivity of automatic door closers and door locks to ensure they function properly in case of fire.
4. Prevent other objects from blocking fire doors during a fire; regularly check surrounding objects.
5. In some cases, such as fire doors in stairwells, electromagnetic door locks can be used for automatic opening in case of fire.
6. Fire door locks should be push-bar type for easy manual or physical pushing to open in an emergency.
