California Warehouse Fire Fills City with Toxic Smoke

A major fire at a Medline medical supplies warehouse in Tracy, California, on June 11 sent thick black smoke across the city, making the air unhealthy to breathe. When medical equipment like gloves and bandages burn in large quantities, they release harmful chemicals and particles. The sprawling facility covers about one million square feet. People nearby were evacuated. Investigators are still determining what caused the fire.
