Dangerous concrete work operation – a concrete polishing machine went out of control. - Video

In the video, when the concrete polishing machine went out of control due to operational error, the worker's attempt to intervene with a bamboo pole to stop the rotating parts posed an extremely high risk and could result in mechanical injury. The following are key response measures and safety guidelines: Upon discovering equipment malfunction, prioritize cutting off the power or activating the emergency stop device to prevent further injury. Establish a warning line to prevent unauthorized personnel from approaching and avoid secondary injuries. Protrusions on the rotating shaft must be equipped with fixed protective covers to prevent clothing or tools from being caught. Regularly check safety limit devices (such as emergency stop buttons and power switches) to ensure the wiring is intact. Operators must receive equipment operation training and are strictly prohibited from starting the equipment without authorization. Operational errors can lead to fatal risks; always strictly adhere to safety procedures to protect lives.
