The document discusses preventing workplace accidents. It explains that accidents can result from unsafe conditions, unsafe acts, or dangerous work. Unsafe acts may occur due to negligence, recklessness, or lack of knowledge. To eliminate accidents, workers must understand their causes, identify unsafe acts, and understand how unsafe acts occur. Unsafe acts can be instantaneous due to inattention or working without plans, or pre-determined through creating unsafe conditions or neglecting safety standards. Companies can form volunteer work safety groups with employees and safety committees to jointly analyze risks and accidents and develop solutions. All workers must participate in ensuring safety.
