Effects of Overexposure If the mercury in a small clinical thermometer were dispersed in a closed 100' x 100' x 15' room,
the TLV would be exceeded. Unsafe conditions are not indicated by odor. Severe poisoning can
occur with less than two hours exposure to high concentrations of vapor. Mercury may be
SECTION I NAME 24 HOUR EMERGENCY ASSISTANCE absorbed slowly through the skin. Repeated or prolonged contacts may result in poisoning. A
single ingestion of a small amount of pure metallic mercury would not be expected to cause
severe injury. However, if the mercury contained mercury compounds, poisoning could result.
