In order to improve the safety management level of confined space operations and enhance the emergency response capabilities for sudden accidents such as toxic and harmful gases, the company conducted an emergency drill for confined space operations in the first half of 2025 on March 31. The company's safety management personnel and operators participated in the drill.

During the simulated dredging operation of the wastewater pipe gallery, personnel were poisoned and suffocated due to the accumulation of harmful gases. Before homework, ensure the safety of the tribe; Ventilation first, testing later, and then operation; Principle: Complete the configuration of protective equipment, mandatory ventilation, and gas detection.

The operator wears protective equipment and enters the pipe gallery, triggering an alarm when suddenly unconscious. The monitoring team immediately initiated emergency response, the safety department synchronized with the environmental safety department to monitor gas data, the equipment department ensured rescue equipment, the medical team implemented cardiopulmonary resuscitation, and completed the transfer and treatment of the injured within 15 minutes.

Director Xu Dongmei of the Comprehensive Management Center pointed out in her summary that this drill has tested the scientific and operational nature of the emergency plan, but there is still a need to optimize and improve individual aspects. Require all departments to deeply learn from the lessons of accidents, strictly implement the approval process for operations, strengthen the "seven prohibitions" principle for confined space operations, solidly identify risks, equip emergency equipment according to standards, and prevent safety accidents in confined space operations.

This drill further enhanced employees' risk prevention awareness and collaborative rescue capabilities through practical scenario simulation. In the future, the company will conduct regular special drills to ensure the effective implementation of safety management in confined space operations and build a solid defense line for enterprise safety production.
