Symptoms of Exposure

Acute Effects:  Eyes: Vapors may cause irritation, redness, tearing and blurred vision.  Skin: May cause irritation with redness and defating of the skin on prolonged contact.  Inhalation: Mists and vapors may cause irritation with coughing, watering of the eyes and sore throat. Overexposure may cause headache, nausea, drowsiness and abdominal pain.  Ingestion: Swallowing may cause gastrointestinal irritation, nausea, vomiting, cramps and diarrhea.

Chronic Effects:  Prolonged or repeated skin contact may cause irritation with redness and defatting of the skin. . n-Methyl-2-pyrrolidone has been found to cause toxicity in the fetus of laboratory animals exposed during pregnancy.

Medical Conditions Aggravated By Exposure:

Individuals with chronic skin disorders may be at risk from exposure.

Primary Route(s) of Entry

Eye, skin, inhalation, ingestion

Emergency First Aid

Eye: Flush eye with water for 15 minutes.  Get medical attention if irritation persists.  Skin: Wash thoroughly with soap and water. Remove contaminated clothing.  Get medical attention if irritation develops.  Inhalation: Remove victim to fresh air. Restore breathing.  Get medical attention.  Ingestion: If conscious, give 1-2 glasses of water to dilute. Do not induce vomiting unless directed to by medical personnel.  Never give anything by mouth to a person who is unconscious or convulsing.  Get immediate medical attention.

VII. Environmental Protection Procedures

Spill Response

Wear appropriate protective clothing.  Dike spill and collect with an inert absorbent.  Prevent runoff from entering sewers or waterways.  Report spills as required.

Waste Disposal Method

Dispose of in accordance with all state, local and federal regulations.

VIII. Special Protection Information

Eye Protection

Skin Protection

Chemical safety glasses or goggles required.

Butyl rubber gloves required.

Respiratory Protection (Specific Type)

Ventilation Recommended

For spray application, a NIOSH approved organic

vapor respirator may be used.

Good general ventilation is usually adequate. If exposure limits are exceeded, local exhaust may be required.

Other Protection

Impervious apron, boots, safety shower, eye wash as needed.

IX. Special Precautions

Hygienic Practices in Handling & Storage

Store in a cool, well ventilated area away from oxidizers and other incompatible substances.

Work Practices

Avoid eye and skin contact.  Avoid breathing vapors.  Wash thoroughly after handling.

Other Precautions

Use only with appropriate protective equipment.  Empty containers retain residue and may be hazardous.
