Several firefighters were hospitalized Thursday morning after extinguishing a hazardous materials-involved fire at a pool supply company in Phoenix.
According to Phoenix Fire, crews were called to the scene near 32nd Street and McDowell Road around 3 a.m.
People nearby reported seeing a large cloud over the area, while ABC15 reporter Justin Pazera reported smelling chlorine in the air.
