assistance. Never induce vomiting or give anything by mouth to a victim who is
unconscious or having convulsions.
?Eye contact: Rinse with copious amounts of water for at least 15 minutes. Get
emergency medical assistance.
?Skin contact: Flush thoroughly with water for at least 15 minutes. Wash affected
skin with soap and water. Remove contaminated clothes and shoes. Wash clothing
before reuse and discard contaminated shoes. Get emergency medical assistance.
?Inhalation: Immediately remove to fresh air. If not breathing, give artificial
respiration. Get emergency medical assistance.
Section VII: Special Protection
Ventilation: Adequate ventilation is required to protect personnel from exposure to
chemical vapors exceeding the PEL and to minimize fire hazards. The choice of ventilation
equipment, either local or general, will depend on the conditions of use, quantity of
material, and other operating procedures.
Respiratory Protection: Use approved respiratory equipment. Follow NIOSH and
equipment manufacturer's recommendations to determine appropriate equipment.
Skin Protection: Protective gloves and clothing are recommended. The choice of material
must be based on chemical resistance and other user requirements. Individuals who are
acutely and specifically sensitive to tetrahydrofuran may require additional protective
equipment.
Eye Protection: Laboratory safety glasses are minimum protection. Goggles are preferred
and may be necessary depending on quantity of material and conditions of use.
Emergency eye wash fountains and safety showers should be available in the vicinity of
any potential exposure. Ground and bond metal containers to minimize sparks.
Section VIII: Spill and Disposal Procedures
If a spill occurs, protect from ignition. Wear protective clothing and use approved
respiration equipment. Absorb spilled material in an absorbent recommended for solvent
spills and remove to a safe location for disposal by approved methods. Use nonsparking
tools. If released to the environment, comply with all regulatory notification requirements.
Waste Disposal: Dispose of tetrahydrofuran as an EPA hazardous waste.
MSDS 40-4120-XX Page 4 of 8 March 24, 2009
Section IX: Storage
Tetrahydrofuran should be protected from temperature extremes and direct sunlight.
Proper storage of tetrahydrofuran must be determined based on other materials stored and
their hazards and potential chemical incompatibility. In general, tetrahydrofuran should be
stored in an acceptably protected and secure flammable liquid storage room. Periodically
check for peroxides in stored material and prior to use, especially before concentration or
heating.
