Yes, fire door handles can be used in both residential and commercial buildings, but there are important differences in their application depending on the type of building and the specific fire safety requirements. In residential buildings, fire door handles are typically installed on fire-rated doors that protect escape routes, such as stairwells or hallways. These handles ensure that the doors remain functional during a fire emergency, allowing residents to evacuate safely. In this setting, fire exit door handles may be simpler but still need to meet fire safety regulations to prevent the spread of smoke and flames. The fire rated door handles used in residential buildings are generally designed for easier access while maintaining a secure closure during normal use. In commercial buildings, the requirements for fire door handles are often stricter due to higher occupancy and the complexity of escape routes. Fire escape door handles and fire door handle bars are commonly used in commercial spaces, particularly in areas with high foot traffic or where panic situations are more likely to occur. Fire door handle sets in these buildings may include additional safety features, like panic bars, that ensure fast and safe evacuation during emergencies. These handles must meet more stringent codes to comply with local building and fire safety regulations.
