In special circumstances, can the exit sign for runners effectively guide the crowd?

In emergency situations, especially in emergencies such as fires and earthquakes, timely and effective crowd guidance is the key to ensuring safe evacuation. As an important part of the emergency evacuation indication system, whether the running man exit sign can effectively guide the crowd is directly related to the life and death of the personnel.
In emergency situations, people's emotions are often easily affected by panic and fear, and fast and clear indication signs can help them quickly determine the direction of escape. If the sign design is not conspicuous or difficult to identify, it may cause confusion in the crowd and increase the difficulty of evacuation. Therefore, the shape, color, size, etc. of the sign should meet international standards and be highly recognizable. The use of a green background color and a white or bright running man icon is the most common design, because this combination has a strong visual impact in the crowd and can attract quick attention.
In an emergency evacuation, people usually do not have time to find an escape exit, so the running man exit sign should be installed in key evacuation passages, exits and corners to ensure that no matter which direction the crowd approaches from, they can see and identify the sign at the first time. If the sign is not properly positioned or does not cover all the places that need guidance, it may cause people to stray into a dead end or miss the nearest exit, thus delaying evacuation time.
In a fire or smoke environment, vision may be severely disturbed, so the running man exit sign should have strong light reflectivity or luminous function. At night or in low-light environments, signs with luminous or reflective materials can effectively improve their visibility in the dark. In addition, some modern signs are also equipped with emergency lighting functions to ensure that the signs can still work effectively in power outages or other low-light conditions.
During emergency evacuations, people's thinking and reactions are often affected by stress, so the transmission of sign information must be concise and clear. The running man icon has been widely accepted as the standard symbol for emergency evacuation guidance because it can intuitively express the meaning of "people walking towards the exit" without any language translation or explanation, thus avoiding confusion caused by language barriers or understanding barriers.
The protective function of the running man exit sign also needs to be considered, especially in harsh environments such as fires and heavy rains. The material of the sign should have certain high temperature resistance, corrosion resistance and wind and rain resistance to ensure that it can still maintain stable performance under special circumstances. This design can ensure the usability of the sign in harsh environments and avoid damage or disappearance of the sign due to external factors.
