Two streets are closed and several homes are being advised to shelter in place or evacuate after an acid spill in Meriden.

The Department of Energy and Environmental Protection Emergency Response Unit responded to the Tradebe facility, where officials say acid spilled from a tractor-trailer into an outdoor containment area.

One of the leaking drums has been determined to contain a mix of hydrofluoric acid, nitric acid and chromium.

The floor of the trailer has been severely damaged and several other drums were also damaged.

The entire trailer and damaged drums will have to be removed.

Duffy and Gracey avenues are closed for several hours while the trailer and drums are safely packaged and removed.

Environmental Services Inc. is also on scene and has been retained by Tradebe to handle remediation activities.
