"Emergency Exit" signs should be set on the walls at both sides and corners of the emergency exit evacuation passage, and the upper edge of the signs should not exceed 1m from the ground. You can also set the sign directly on the ground and cover it with a non-combustible transparent and firm protective plate. The spacing between signs should not be greater than 20m, and the distance between the end of the bag-shaped walkway and the signs should not be greater than 10m.
"Requirements for Setting Fire Safety Signs" stipulates the setting principles of fire safety signs and the eye-catching position of the signs. They should be set on movable objects such as door and window frames to avoid contradictions and duplication. The direction should be chosen at the passage, and the observation angle of most observers should be close to 90 degrees.
In order to evacuate people quickly and safely in the event of accidents, a sufficient number of safety exits must be set in the fire protection design of buildings. There should be no less than two safety exits in each building or fire zone. The horizontal distance between two adjacent safety exits in each fire zone or the nearest edge of the evacuation exit in each room should not be less than 5.0m The exits should be evenly distributed and clearly marked. Buildings with fire resistance ratings of Grade I and Grade II.
Tips: When setting fire safety evacuation signs, the contents of the signs should be clear, concise and definite, consistent with what needs to be expressed, and should not contradict each other.
