Reports of Carcinogenicity:NTP:UNKNOWN	  IARC:UNKNOWN	  OSHA:NO
Health Hazards Acute and Chronic:INGESTION: MENTAL SLUGGISHNESS.
    INHALATION: CAUSES IRRITATION OF NASAL PASSAGES AND THROAT. CAUSES
    STUPOR (CNS DEPRESSION). SKIN: MODERATE SKIN INJURY, DRYING,
    DERMATITIS. EYE: LIQUID AND VAPORS ARE I RRITATING. CAN CAUSE
    SEVERE INJURY- DAMAGE REVERSIBLE
Explanation of Carcinogenicity:MFG. STATES "NO INFORMATION"
Effects of Overexposure:EYES: SEVERE INJURY. SKIN: DRYING OF SKIN,
    DERMATITIS. INHALATION: STUPOR (CENTERAL NERVOUS SYSTEM
    DEPRESSION). INGESTION: SLUGGISHNESS.
Medical Cond Aggravated by Exposure:SIGNIFICANT EXPOSURE TO THIS
    CHEMICAL MAY ADVERSELY AFFECT PEOPLE WITH CHRONIC DISEASE OF
    RESPIRATORY SYSTEM, SKIN, PERIPHERAL NERVOUS SYSTEM, CENTRAL
    NERVOUS SYSTEM, AND/OR EYES.

=======================  First Aid Measures  =======================

First Aid:INGESTION: DO NOT INDUCE VOMITING, GIVE 2 GLASSES WATER/MILK.
    CONTACT A PHYSICIAN. INHALATION: REMOVE PATIENT FROM CONTAMINATED
    AREA. IF NOT BREATHING GIVE ARTIFICAL RESPIRATION, THEN OXYGEN IF
    NEEDED . CONTACT A PHYSICIAN IMMEDIATELY. SKIN:REMOVE CLOTHES/WASH
    CONTAMINATED SKIN WITH WATER. IF IRRITATION PERSISTS, CONTACT A
    PHYSICIAN. EYES: FLUSH WITH WATER FOR AT LEAST 15 MIN, CONTACT

Extinguishing Media:USE CARBON DIOXIDE OR DRY CHEMICALS FOR SMALL
    FIRES, ALCOHOL-TYPE AQUEOUS FILM-FORMING FOAM OR WATER SPRAY ON
    LARGE FIRE
Fire Fighting Procedures:IF POTENTIAL EXPOSURE TO VAPORS/PRODUCTS OF
    COMBUSTION EXISTS,	WEAR COMPLETE PROTECTIVE EQUIPMENT. WATER SPRAY
    CAN BE USED TO REDUCE INTENSITY OF FLAME.
Unusual Fire/Explosion Hazard:VAPOR HEAVIER THAN AIR AND CAN TRAVEL
    GREAT DISTANCE TO A SOURCE OF IGNITION AND FLASHBACK.  MATERIAL
    CREATES SPECIAL HAZARD BECAUSE TO FLOATS ON WATER.

==================  Accidental Release Measures  ==================

Spill Release Procedures:ELIMINATE IGNITION SOURCES. AVOID EYE/SKIN
    CONTACT.PLACE LEAKING CONTAINERS IN WELL VENTILATED AREA WITH SPILL
    CONTAINMENT. IF FIRE POTENTIAL EXIST, BLANKET SPILL WITH  ALCOHOL
