It includes an assessment of chemistry health and exposure data from studies in animals and humans exposed to raw asphalt paving and roofing asphalt fume condensates and asphalt based paints.
Exposure to roofing tar fumes.
Over a half million workers are exposed to fumes from asphalt a petroleum product used extensively in road paving roofing siding and concrete work 1.
Roofing heated asphalt is used for sealing roofs.

Criteria for a recommended standard.
Occupational exposure to asphalt fumes.
Asphalt is heated to pave roads and seal road cracks.
Most important the document serves as a basis for identifying future research to reduce occupational exposures to asphalt.
Laboratory studies of roof tar extracts have shown dna changes in human fetal cells exposed to asphalt fume extracts.
According to niosh the exposure limit of exposure to asphalt fumes should not exceed 5mg m 3 in any 15minute period and 0 5mg m 3 over 8hours exposure.
When hot asphalt is applied in a molten state it generates toxic fumes.
Using hot roofing tar can easily cause odor complaints because the odor is strong pungent and can be smelled at very low concentrations in the air.
Workers exposed to asphalt fumes are at risk of developing headaches rashes cough and possibly cancer.
Odors from rubber roof adhesives have a sweet organic odor solvent odor that people begin to smell when the concentration in air is much higher.
Asphalt fumes over a half million workers are exposed to fumes from asphalt a petroleum product used extensively in road paving roofing siding and concrete work.
Safety precautions when exposed to asphalt fumes do not eat or smoke while working with asphalt.
