ACUTE EXPOSURE INFORMATION

1. WITH POISONING/EXPOSURE
   1. The majority of hot tar burns involve only 3 to 5% of the body surfaces. Partial thickness burns are most common, but patchy areas of full thickness skin losses are commonly observed.
      1. Inhalation of hot asphalt fumes can produce eye and respiratory tract irritation, headache, nausea, and nervousness due to the formation of hydrogen sulfide gas.
      2. Serious hydrogen sulfide poisoning can occur from inhalation of hydrogen sulfide evolved from asphalt in closed tanks. Oral ingestion of cool asphalt is relatively non-toxic.
      3. Asphalt cooled in a closed tank can evolve high concentrations of hydrogen sulfide gas, carbon monoxide, propane, methane, and other aliphatic hydrocarbons, as well as producing a relatively hypoxic atmosphere.
