All test results below provided by US EPA
Lead in ambient air: Four samples in hot zone were collected. Highest was 1.9 micrograms per cubic meter. Other samples < 1.5 micrograms per cubic meter (National Air Quality Standard), OSHA PEL is 50 micrograms per cubic meter.
Interpretation: Lead levels in ambient air well below levels for worker concern. Personal monitoring pending.
Volatile organic compounds in ambient air: 3 samples were collected around the debris pile. Low levels of VOCs, no immediate health concerns. 2 samples were collected in the plume - Benzene detected at 100 parts per billion, just at OHS A PEL.
Interpretation: VOC exposures for most workers should be low, but potential exposures exist. Appropriate respiratory protection should continue to be worn.
Miscellaneous toxic and acid gasses (by direct reading instruments): low levels of phosgene and hydrogen cyanide present.
Interpretation: No immediate public or occupational health threat. Personal air sampling pending. Appropriate respiratory protection should continue to be worn.
