Carbon Dioxide samples were taken using a Telaire 0 - 2000 ppm infrared
direct-reading instrument, sensitive to 1 ppm,
Levels measured throughout the facility were below 1000 ppm. The OSHA
(workplace) Permissible Exposure Limit is 5000 ppm. The Federal
Government’s Public Building Service recommends a limit of 1000 ppm in
"non-industriar areas, including general officas and day care centers.
Therefore, the facility is acceptable. It should be noted that once the
building systems are turned on, the levels of Carbon Dioxide will .fell from
their present levels since more fresh air will be introduced to the building.
