Abstract: Petrochemical unit inspection and maintenance operation is heavy work that needs to be done in short time. And most of the process media are flammable, explosive, toxic and hazardous substances. There are many types of high-risk operations and confined space operation is one of them. Slight negligence in the operation process is accident-prone. Once accident occurs, it is difficult to rescue workers from the confined space and blind rescue may even lead to increased number of casualties. Based on the characteristics of confined space operations, the safety management strategy is specifically elaborated from the three stages of operations involving pre-operation preparation, safety management during the operation, and interruption and shutdown of the operation. Common errors are summarized and corrective measures are proposed. These can provide reference for the safety of confined space operations in unit inspection and maintenance projects of petrochemical enterprises.

Key words: petrochemical plant inspection and maintenance; confined space operation; safety management
