On the afternoon of April 25, 2025, during the 23rd National Occupational Disease Prevention and Control Law Promotion Week, under the guidance of the Economic Development Zone and Emergency Management Bureau, Zhejiang Chuangfeng and Zhejiang Guangli jointly held a limited space emergency drill.

Toxic gases (such as carbon monoxide, hydrogen sulfide, etc.) in confined space operations are known as the "silent assassins" in the workplace, which can easily cause poisoning and suffocation accidents. In case of improper operation, gases such as hydrogen sulfide and carbon monoxide can cause coma within seconds, and blind rescue is more likely to cause secondary casualties. The company has always attached great importance to this aspect. Since the beginning of the limited space operation, the company has been equipped with gas detection equipment, respiratory equipment, ventilation equipment, safety ropes, and other work equipment. Every year, regular limited space operation training and emergency drills are held to ensure that the operators understand the work process and remember the precautions.

Emergency Four Step Life Saving Guide

1. Immediately cut off the source: turn off the equipment, cut off the gas source, and start the explosion-proof fan for forced ventilation!

2. Scientific testing: Use a portable detector to confirm that oxygen (≥ 19.5%) and toxic gases meet the standards before entering.

3. Safety rescue: Rescuers must wear positive pressure respirators and safety ropes! Transfer the poisoned person to a well ventilated area, loosen their collar to ensure smooth breathing.

4. Emergency medical treatment

Awakened person: Lying on the side to prevent suffocation

Coma: cardiopulmonary resuscitation+immediately call 120 (indicating the type of toxic gas and requesting support from a hyperbaric oxygen chamber!)

Prevention checklist

✅ Before homework: Online reporting

✅ Equipment inspection: Respirators, detectors, and ventilation equipment are indispensable

✅ Intelligent upgrade: Install real-time gas monitoring and alarm devices to reduce human risk by 90%
