                          SECTION V - HEALTH HAZARD DATA

 
ACUTE EFFECTS:
            Eye:   Direct contact irritates moderately with redness
                   and swelling. 
            Skin:  A single short exposure (less than 24 hours) may
                   irritate. Repeated prolonged contact (24 to 48 
                   hours) may irritate moderately. 
            Inhalation: Vapor overexposure may irritate eyes, nose and
                        throat. 
            Oral:   Small amounts transferred to the mouth by fingers
                    during use, etc. should not injure. Swallowing
                    large amounts may cause digestive discomfort.

                       soap and water or waterless cleanser. Get
                       medical attention if irritation or other ill effects
                       develop or persist. 
            Inhalation;  Remove to fresh air.
            Oral:        No first aid should be needed.
