The opening angle of a fire door is a critical factor that impacts the width of evacuation routes. While fire doors and conventional evacuation doors typically open at up to 120° or even 150°, it is recommended to limit the opening angle to 90° to ensure maximum clear evacuation width.
It is important to ensure that repeated opening of the door does not compromise its reliability. While fire doors and evacuation doors are designed to open at wider angles, the reliability test for fire door opening angles is typically set at 70°. Exceeding this angle over time can lead to a decline in product quality. Therefore, setting the opening angle of evacuation doors at 90° strikes a balance between functionality and maintaining product quality.
