A lithium ion battery is to blame for a massive fire in Camden Friday night that ignited a metal recycling scrap yard into flames and caused 100 families in the city to voluntarily evacuate, according to a Camden spokesperson.

EMR shredding facility was wrongly sent the battery, which was concealed and undetectable within scrap metal, setting off a fire around 5 p.m. with plumes of smoke in the sky that could reportedly be seen 15 miles away.

No injuries were reported and fire crews had the blaze under control by 1 a.m. Saturday, but the scrap yard suffered extensive damage and will need major repairs.

In a statement, EMR said the company has never accepted batteries for disposal or recycling, and repeated calls for the state and federal governments to regulate risks of lithium ion batteries in particular.

EMR covered the cost of meals and hotels for residents who live near the facility.

But neighbors have complained about the site for years, citing other fires and conditions at the property.
