ANSONIA, Conn. (May 15)—Fire and company officials are investigating the cause of a blaze that felled Latex Foam Products Inc.'s 284,000-sq.-ft. primary manufacturing site, housed on a 10.5-acre site in Ansonia, and forced the evacuation of surrounding buildings. The facility virtually burned to the ground and, at least temporarily, ended production of the firm's latex foam mattress cores, pillows, mattress pads and cosmetic sponges. The plant also produced industrial latex goods for automotive and industrial uses. No injuries were reported, the company said, and it is still accessing the damage. The fire left about 240 workers without jobs for the time being. On an average week, Latex Foam Products makes about 25,000 pillows, 1,350 mattresses and more than a million cosmetic sponges, a company spokeswoman said. Part of the LIS Corp. group of companies, Latex Foam Products also has plants in California and France. It did not say if those facilities would pick up the manufacturing slack.
