* THF can affect your breathing
through your skin.
* how flammable is thf should be used as
Carcinogens - use extreme caution.
* Contact will severely irritate and burn skin and eyes and may cause eye damage. Repeated skin contact can
Causes dryness, cracking and rashes.
* Inhalation of THF can irritate the nose and throat
and lungs causing coughing, wheezing and/or shortness of breath
* THF can cause headaches, nausea and
Dizziness. Very high exposures can cause loss of consciousness
* THF may damage the liver and kidneys.
* Tetrahydrofuran is a flammable liquid,
Dangerous fire hazard.
Tetrahydrofuran is a colorless liquid with an ether-like odor. Used as a solvent for monomers, natural and synthetic resins, and as a chemical intermediate.
* Tetrahydrofuran is on the list of hazardous substances
Because it is regulated by OSHA and referenced by ACGIH,
DOT, NIOSH, NFPA, and EPA.
* This chemical is a special health hazard
listed because it is a carcinogen and is

How to find out if you are
The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information and training on chemical hazards and controls. The federal OSHA Hazard Communication Standard 1910.1200 requires private employers to provide similar training and information to their employees.
Exposure to hazardous substances should be assessed regularly. This may include collecting personal and area air samples. You can obtain a copy of the sampling results from your employer. You have a legal right to obtain this information under OSHA 1910.1020.
* If you think you are experiencing any work-related health problems, see a doctor trained in identifying occupational diseases. Keep this fact sheet with you.
* Odor Threshold = 31 ppm.
* The range of acceptable odor thresholds is quite wide
broad. Caution should be exercised when relying solely on smell as a warning of potentially hazardous exposure.
Workplace Exposure Limits
Occupational Safety and Health:
The average airborne permissible exposure limit (PEL) for an 8-hour work shift is 200 ppm.
The recommended airborne limit is 200 ppm averaged over a 10-hour work shift, and 250 ppm for STEL, not to be exceeded during any 15-minute work period.
The recommended airborne limit is 50 ppm averaged over an 8 hour work shift and the STEL (Short Term Exposure Limit) is 100 ppm.
* Tetrahydrofuran is a probable human carcinogen. There may be no safe level of exposure to carcinogens, so all exposure should be reduced to the lowest possible level.
* The above exposure limits apply at air level only. When skin contact also occurs, you may be overexposed even if air concentrations are below the limits listed above.
