The present invention relates to a safety belt for a work which is formed by connecting a shoulder belt, a chest belt, a back belt, and a bottom belt to surround the legs, waist, and shoulder of a worker, and in which a life rope having a safety ring and an impact absorption part is connected to the intersection part of the back belt. The safety belt for a work comprises a hook coupled to one side of the shoulder belt to hook the safety ring; a hook detection part installed in the hook to detect whether or not the safety ring is hooked; a falling detection part installed in the impact absorption part to detect whether or not impact is absorbed by the impact absorption part; an alarm sound speaker for generating alarm sound by receiving a signal generated by the hook detection part and the falling detection part; and a power supply part for supplying power to the hook detection part, the falling detection part, and the alarm sound speaker. When the safety ring is hooked on the hook or the impact is absorbed by the impact absorption part, the safety belt for a work generates the alarm sound while transferring the signal from the hook detection part or the falling detection part to the alarm sound speaker. In the present invention, the hook detection part for detecting whether or not the safety ring of the life rope is hooked on the hook of the shoulder belt and the falling detection part for detecting whether or not the impact is absorbed by the impact absorption. Thus, the safety belt for a work makes a worker recognize safety consciousness by generating the alarm sound through the alarm speaker when the safety ring is hooked not on a site construction but on the hook or the impact is absorbed by the impact absorption part and makes other workers recognize a falling accident when the worker falls. |
