Lockout Tagout – Danger zone
There are two main reasons: personnel’s operation error and straying into dangerous area.

The main reasons for personnel operation errors are:
1. The noise generated by machinery makes the operator’s perception and hearing paralyzed, resulting in difficult judgment or judgment error. Operating or controlling machinery based on faulty or incomplete information. 3 Mechanical display, indicating signal and other display errors make the operator misoperate. The identification and standardization of the control and control system are not good enough to cause the operator to make operational errors. Time pressure causes problems to be dealt with without sufficient consideration. 6 lack of understanding of the danger of moving machinery, resulting in operational errors.
7. Poor technical skills and improper operation methods. Inadequate preparation, inadequate arrangement, and hasty operation result in mistakes. Improper operation procedures, inadequate supervision and inspection, illegal operation.

The main reasons for straying into dangerous areas are as follows:
Changes in operation of the machine, such as changing operating conditions or improving safety devices into dangerous areas. Figure 2. The mentality of saving trouble and taking shortcuts. For familiar machines, they will intentionally omit certain procedures and enter dangerous areas by accident. Forget danger zone under conditioned reflex, or do not indicate danger zone, operator by mistake. The monotonous and boring operation makes the operator tired and enter the dangerous area. 5. Go into danger area due to visual or auditory errors caused by physical or environmental influence. Wrong thinking and memory, especially new workers who are not familiar with the machine and operation are easy to enter the danger zone. The operator failed to resist the wrong command by the commander and entered the dangerous area. 8 bad information communication and into the danger area.
