The explosions people heard were most likely a propane tank blowing up. Propane is used to power some of the company’s equipment.

CBS2’s Tom Wait spoke to family members of the business’ owner.

The business was closed at the time the fire was reported.

Ramirez Pallets was first opened in 1977.

Judy Ramirez, daughter of the owner, told Wait, “I’m just more concerned for my parents. They’ve worked so hard.”

Maribel Sanchez, whose brother owns the business, echoed that sentiment. “God is going to help us. We have a lot of faith in God. And I know Ramirez Pallets will go up again,” she said. “We know we are going to rebuild.”
