Description

technical field [0001] The invention relates to the field of fire safety equipment, in particular to a fire safety warning device.

Problems solved by technology

[0004] When artificial warning is adopted, it not only occupies the police force of fire rescue, but also because the position of firefighters is a warning position, it brings certain danger to the life of warning personnel, especially in high-altitude road rescue, which has been done many times Due to the inconspicuous warning facilities, drivers hit rescuers and vehicles while driving, which brought secondary disasters to rescue work

[0005] Although the way of using the warning device has played a symbolic warning role, the effect is not very good, and the reminder intensity is not high enough. For example, if the commonly used warning belt is used, pedestrians often pull up the warning belt to enter the safety warning area out of curiosity.
