As of today, the tragic explosion caused by a Sinopec oil pipeline in Huangdao District, Qingdao City, continues to haunt the hearts of many. The sight of roads split apart and streets turned into rivers serves as a painful reminder of the devastation. This incident echoes the Dalian pipeline explosion in 2010, where harmful gases from the accident posed serious threats to the local environment and ecosystems.
According to the Propaganda Department of the Working Committee of the Qingdao Economic and Technological Development Zone (Huangdao District), approximately 18,000 residents from 12 communities have been evacuated. Dexian Road Primary School, located on the western side of the affected area, has distributed masks to students. Despite these efforts, smoke from the fire continues to spread toward the city center, raising concerns among locals.
The Qingdao Environmental Protection Bureau reported that at the northwest intersection of Wuhu Island Street and Huaihe Road, the concentration of non-methane hydrocarbons reached 2 mg/m³—well within the national limit of 4 mg/m³. At another monitoring point near the intersection of Huaihe Road and Penghudao Street, the level was recorded at 1 mg/m³. These readings suggest that current air quality remains within safe limits, but the situation is still being closely monitored.
In a preliminary report released via its official Weibo account, the Qingdao Municipal Environmental Protection Bureau confirmed that non-methane hydrocarbon levels downwind from the incident site have not exceeded safety standards. Non-methane total hydrocarbons refer to all volatile hydrocarbons except methane. When concentrations rise beyond acceptable levels, they can cause direct harm to human health, irritate the eyes, respiratory tract, and skin, and even contribute to the formation of photochemical smog under sunlight, further threatening both the environment and public health.
Experts from the EPA, interviewed by China Labor Safety Net, explained that the explosion released various irritating gases that may spread with the wind. These substances can cause localized damage, such as irritation to the eyes, throat, and skin, and in some cases, lead to more systemic health issues.
To protect themselves, experts recommend that local residents take extra precautions, including wearing appropriate face masks or protective gear and applying skin ointments when necessary. Staying informed and following official guidance is crucial during such events.
