First Aid Measures

Ingestion
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
Inhalation
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration.
Skin
Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops.
Eyes
Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.
Handling
Wash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.

Hazards Identification

Inhalation
Large oral dose may produce symptoms of narcosis, incoordination, and kidney damage.
Skin
No adverse health effects expected. Prolonged contact may cause slight irritation.
Eyes
May cause mild irritation, possible reddening.
Ingestion
A nonvolatile liquid - vapor inhalation is unlikely. Inhalation of high vapor concentrations may cause respiratory tract irritation and have a narcotic effect with symptoms of drunkenness.
Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

Exposure Controls/Personal Protection

Personal Protection
Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.
Respirators
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Exposure Effects
Chronic exposure may cause kidney damage.
Poison Class
4

Fire Fighting Measures

Flash Point
121
Autoignition
350
Fire Fighting
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Containers may explode when heated. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. Water spray may cause frothing. Cool containers with flooding quantities of water until well after fire is out.
Upper exp. limit
15.3
Lower exp. limit
2.4
Fire Potential
Low fire hazard, when exposed to heat or flame. Not considered to be an explosion hazard.

Accidental Release Measures

Small spills/leaks
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Remove all sources of ignition. Provide ventilation.

Stability and Reactivity

Disposal Code
1
Stability
Stable under normal temperatures and pressures.
Incompatibilities
Strong inorganic oxidizers, nitric acid, strong hydrogen peroxide
Decomposition
When heated to decomposition, emits tetrahydrofuran and carbon oxides.
Combustion Products
Carbon dioxide and carbon monoxide may be produced in fire.
