On Thursday evening, local officials issued statements regarding air quality in the region:
San Joaquin County Office of Emergency Services
Ongoing Fire Prompts Health Advisory, Air Quality Monitoring, and San Joaquin County officials are urging residents to take precautions as the fire at the Medline Industries facility continues to burn, generating significant amounts of black smoke that may affect nearby communities.
“First and foremost, I want to thank the firefighters, law enforcement and emergency medical personnel, emergency managers, public health officials, and all of the agencies working around the clock to respond to this incident. Their professionalism and coordinated efforts have prevented a much larger disaster and continue to protect our community. Protecting the health and safety of our residents is our top priority. We will continue working closely with local, state, and regional partners to monitor conditions, provide timely information, and ensure the resources necessary to support this response remain available,” commented District Five Supervisor Robert Rickman.
While fire personnel remain actively engaged in suppression efforts, smoke from structural fires can contain a mixture of gases and fine particles that may pose health risks, particularly for children, older adults, pregnant individuals, and people with asthma, heart disease, or other respiratory conditions.
“Among the chemicals that were consumed in the Medline fire were an assortment of respiratory irritants, toxic gases, carcinogens, and at least one neurotoxin,” said Dr. Maggie Park, Public Health Officer, San Joaquin County Public Health Services. “If anyone in the vicinity of the smoke plumes inhaled the smoke and is experiencing sudden onset respiratory problems, headaches, dizziness, nausea, or throat irritation, they should report to their nearest emergency department for further evaluation and treatment.”
Community members, especially older adults, young children, pregnant individuals, and those with chronic heart or lung conditions are encouraged to take the following precautions if they are in areas affected by smoke:
Stay indoors and limit outdoor activity.
Keep windows and doors closed.
Use air conditioning in recirculation mode, if available.
Bring pets indoors.
Avoid strenuous outdoor exercise.
Monitor local air quality conditions and forecasts.
Seek medical attention if having trouble breathing, chest pain, or other serious symptoms.
The County Emergency Operations Center is activated and monitoring the situation and facilitating resource coordination, situational awareness, public information, and interagency communication. County departments are working alongside fire agencies and partner organizations to assess potential community impacts and address emerging needs.
Environmental and air quality monitoring efforts are ongoing, and the San Joaquin Valley Air District continues to provide updates and guidance for communities that may be affected by smoke. Residents are encouraged to stay informed through official county communication channels and to monitor current air quality conditions through AirNow.gov.
San Joaquin County will continue to provide updates as new information becomes available.
San Joaquin Valley Air Pollution Control District
A large warehouse fire in Tracy, San Joaquin County, is generating significant smoke that may affect air quality in portions of the San Joaquin Valley in the next few days. Depending on wind and weather conditions, smoke from the fire may result in elevated concentrations of fine particulate matter (PM2.5) in nearby and surrounding communities.
Residents in the immediate area of the fire and in downwind regions throughout the Valley that are impacted by smoke are encouraged to remain indoors, keep windows and doors closed, use air filtration when available to reduce exposure, and follow additional recommendations from their medical professionals and local health authorities. The potential for increased air quality impacts will remain until the fire is extinguished and smoke impacts diminish. The District is working with San Joaquin County Office of Emergency Services and other state and local partners to assess potential impacts while continuing to monitor the situation.
Fire smoke contains particulate matter (PM) and other pollutants which can trigger asthma attacks, aggravate chronic bronchitis, and increase the risk of heart attack and stroke. Those with existing respiratory conditions are especially susceptible to the adverse health effects of this form of pollution. Anyone experiencing poor air quality due to wildfire smoke should move indoors to a filtered, air-conditioned environment with windows closed and contact their primary care provider for more information.
