OTO Sponsors "Baseball: The Tenth Inning" on WGBY

When we heard the news that Ken Burns’ “baseball” special, "The Tenth Inning", would contain detailed coverage of the Red Sox 2004 and 2007 World Series championship seasons, we wanted to be part of it! We proudly sponsor WGBY and Public Television and we are delighted to be a part of bringing this type of programming to western Massachusetts. Inside of Route 495, they may consider us to be from the Midwest, but western Mass Red Sox fans have all the passion for the game as our eastern Mass cousins. On September 28th and 29th, our TVs will be tuned-in to help us relive the glory of 2004 and 2007.

PCBs in Building Caulk: A Hidden Problem Surfaces

A possible health risk to building occupants from polychlorinated biphenyls (PCBs) is coming back into the news; and this can be particularly bad news for building owners. It turns out that the caulking material used to fill seams, cracks and void spaces in buildings in the past often contained high concentrations of the persistent environmental contaminant PCBs. The concern is heightened for buildings constructed, repaired or added on to in the period between about 1950 and 1978; PCBs were banned after this time.

Scientific studies conducted over the past 10 years have demonstrated a relationship between the presence of PCBs in caulk and low concentrations of PCBs in the indoor air inside of buildings. No one has yet shown that these very low concentrations of PCBs in air actually pose a health hazard, but in a number of cases EPA has taken the adamant position that any exposure to PCBs in air (particularly inside of schools) is hazardous to human health, and therefore the material must be removed.
