The filling and use of energy isolation list is not standard, such as: the filling of isolated materials and energy is not correct;
Incorrect or irregular identification of hazard factors;
The isolation mode is not standardized;
Missing items such as signature and date; Not hanging, Posting and retaining according to document requirements.
