The Rhode Island news with Great White says it had permission for fireworks:
One year after the fire, American Foam put a warning on the state’s invoice for foam
The president of the company that sold the polyurethane foam to The Station is fairly certain his company did not give the owners a written warning about the flammability of their product.
Aram DerManouelian, president of American Foam in Johnston, told the grand jury his company did sell fire-retardant foam to schools. And he said the company would supply a safety sheet when requested by a buyer.
But DerManouelian said he doubted the company included an MSDS safety sheet with the order. He said that was not the company’s practice.
