A fire broke out at a phosphorus chemical enterprise in Yunnan due to material loading and unloading operations.

On August 5, the People's Government of Jinning District, Kunming City, released an official announcement. At 11:50 on August 4, 2026, a fire broke out during material loading and unloading operations at the factory of Yunnan Haoming Fine Phosphorus Chemical Co., Ltd. in Erjie Town, Jinning District.

After the fire occurred, local authorities quickly set up an on-site emergency command headquarters to coordinate efforts from emergency services, fire departments, ecology and environment agencies, health departments, and the management committee of the industrial park to carry out response work. A total of 1,257 employees and nearby residents were evacuated in a timely manner, and the involved enterprise simultaneously suspended production and operations. Following continuous response efforts, the open fire was completely extinguished at 22:07 on the same day. The incident caused no casualties, and the specific cause of the fire is under investigation.

The smoke and dust generated by the fire caused short-term disturbances to air quality in localized areas. The ecology and environment department immediately set up monitoring points to conduct continuous emergency monitoring. Monitoring data showed a phased increase in the concentration of relevant pollutants in the area. Through various pollution control measures, as of 08:00 on August 5, pollutant indicators showed a downward trend. The relevant smoke and dust are irritating and can easily cause symptoms such as dry throat and eye discomfort. Relevant departments continue to conduct follow-up monitoring and issue health advisories.

The local government expresses deep apologies for the impact of the fire on the lives of nearby residents. Next steps will include urging the involved enterprise to implement comprehensive rectifications, continuously releasing follow-up progress on the incident, and responding to public concerns in a timely manner. Meanwhile, the public is advised to rely on official information and not to spread or believe rumors.
