A fire official says a mechanical failure apparently caused two explosions at a food laboratory in northern New Jersey, leaving two workers with cuts and bruises.
Totowa Fire Marshal Allen Del Vecchio tells The Star-Ledger he felt the blast from Pharmachem Laboratories in Totowa at his house a mile away.
Pharmachem produces ingredients that flavor foods. Workers say they had just started on a new recipe for eggnog when the blast occurred.
Del Vecchio says the first explosion apparently came from a furnace-like device that was heating a vat containing eggnog flavoring ingredients. A subsequent blast apparently involved a pocket of hot air or gas that had built up inside the vat.
The entire rear of the building was blown out.
