The Agency estimates the cleanup will take five to six months.

The building housed more than 500,000 pounds of batteries, including more than 140,000 pounds of lithium batteries, many of which were consumed in the fire. Lithium batteries contain a flammable electrolyte that can become pressurized when damaged, causing them to rupture which can cause overhearing, fire and explosion. Other items containing potentially hazardous materials including solar panels and waste electronics were also found at the warehouse.
