Tracy's Air Quality Deteriorates After Medline Warehouse Fire Burns Medical Supplies

A five-alarm fire at a Medline Industries warehouse in Tracy, California on June 11, 2026, sent thick black smoke across the city and degraded air quality to unhealthy levels. Medical equipment and supplies—gloves, gowns, wound care products—release complex particulate and chemical byproducts when burned at scale. The facility spans roughly one million square feet. Evacuations were ordered in the immediate vicinity. The fire's cause remains under investigation as of June 13, 2026.
