An evacuation door is different from a fire door. An evacuation door may be a fire door, but it does not necessarily have to be a fire door. These two items are related to human life. Fire doors and related hardware control the fire at the initial stage. If it cannot be controlled, it will prevent the spread of fireworks. Finally, it will also protect the evacuation channel and allow people more time to evacuate.
The evacuation door hardware is designed to allow people to open the door faster in an emergency, with just one motion, and the evacuation door can be opened with any part of the body.
Since Europe and the United States have different evacuation door requirements, China has also formulated the JG/T standard.
Europe requires that an evacuation door escape device be installed on the last escape door leading to the outside, while the United States requires that an evacuation door escape device must be installed on all escape doors (including the entrance and exit of the building).

Design requirements for evacuation routes in the UK
1.1 There must be multiple evacuation passages in the building. The width and quantity of the evacuation passages are determined according to the flow of people in the building.
1.2 When designing the evacuation channel, set the safe minimum value of the evacuation channel, because this channel will not be blocked by smoke and fire. It is necessary to ensure that people can be evacuated within 2-3 minutes in any channel.
1.3 During the architectural design, the evacuation passage is not allowed to be partially narrowed, and the width must be uniform along the passage, because it will form a bottleneck and block the flow of people.
1.4 The doors of the evacuation passages must not be locked. If necessary for security, they must be very easy to open, that is, they can be opened with a single action.
1.5 To ensure that the evacuation door is easy to open but also to ensure the security requirements.
1.6 Evacuation routes must be clearly marked.
1.7 There are the following restrictions on the distance of evacuation routes. Figure 3.1-1
1.8 Specifications for evacuation routes refer to the UK’s Fire and Escape Codes
