SECTION 6 EFFECTS OF EXPOSURE
ENTRY ROUTE INHALE - YES INGEST - YES SKIN - YES EYE - YES
INHALATION
May cause irritation of mucous membranes, nose & throat, headache, dizziness,
nausea, numbness of the extremities and narcosis in high concentrations. Has caused
CNS depression & liver damage in animals, & high concentrations have caused
retardation of fetal development in rats.
TETRAHYDROFURAN
WARNING
The National Toxicology Program has reported that exposure of mice and rats to
Tetrahydrofuran (THF) vapor levels up to 1800 ppm 6 hr/day, 5 days/week for their
lifetime caused an increased incidence of kidney tumors in male rats and liver tumors
in female mice. The significance of these findings for human health are unclear at this
time, and may be related to "species specific" effects. Elevated incidences of tumors
in humans have not been reported for THF. THF is not listed as a carcinogen by NTP,
IARC, or OSHA. One THF vendor has recommended a reduction in the "acceptable
exposure limit" from 200 ppm to 25 ppm, 8 and 12 hour time weighted average.
