SECTION 4.                FIRST AID

Eyes:          Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact

               lenses, if present, after the first 5 minutes, then continue rinsing eye. Call a poison control

               center or doctor for treatment advice.

Skin:          Take off contaminated clothing. Rinse skin immediately with plenty of water for 15-20

               minutes. Call a poison control center or doctor for treatment advice.

Ingestion:     CALL A PHYSICIAN OR POISON CONTROL CENTER IMMEDIATELY. Do not give

               anything by mouth or induce vomiting unless instructed by a physician.

Inhalation:    Remove victim to fresh air. If not breathing, give artificial respiration, preferably mouth-to-

               mouth. Get medical attention.

Notes to Physician and Veterinarian: This product reduces clotting ability of the blood and may cause

               hemorrhaging. If ingested, administer Vitamin K1 intramuscularly or orally as indicated for

               bishydroxycoumarin overdoses. For human cases, Vitamin K1 is antidotal at doses of 10-20

               mg total (not mg/kg). For animal cases, Vitamin K1 is antidotal at 2-5 mg/kg. Repeated

               doses may need to be given, based on monitoring of prothrombin times. In severe cases,

               blood transfusion may be necessary.
