=====================  Hazards Identification  =====================

LD50 LC50 Mixture:LC50: 800,000 PPM-RAT; ORAL ALD: 1000 **
Routes of Entry: Inhalation:YES  Skin:YES  Ingestion:YES
Reports of Carcinogenicity:NTP:NO    IARC:NO	OSHA:NO
Health Hazards Acute and Chronic:INHALATION MAY CAUSE HEART
    IRREGULARITIES, UNCONSCIOUSNESS OR DEATH. INTENTIONAL MISUSE CAN BE
    FATAL. VAPOR REDUCES OXYGEN AVAIL FOR BREATHING & IS HEAVIER THAN
    AIR. LIQUID CONTACT CAN CAUSE FROSTBITE . OVEREXPOSURE BY
    INHALATION, INGESTION, SKIN, EYE CONTACT MAY CAUSE: TEMP NERVOUS
    SYSTEM DEPRESSION W/ANESTHETIC***
Explanation of Carcinogenicity:**MG/KG-RAT.
Effects of Overexposure:***EFFECTS SUCH AS DIZZINESS, HEADACHE,
    CONFUSION, INCOORDINATION & LOSS OF CONSCIOUSNESS; TEMPORARY
    ALTERATION OF THE HEART'S ELECTRICAL ACTIVITY W/IRREGULAR PULSE,
    PALPITATIONS OR INADEQUATE CIRCULA TION OR THE EFFECTS OF EXCLUSION
    OF OXYGEN W/GROSS OVEREXPOS. SIGNIFICANT SKIN PERMEATION AFTER
    CONTACT APPEARS LIKELY.

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

First Aid:INHALATION: REMOVE TO FRESH AIR. IF NOT BREATHING, GIVE
    ARTIFICIAL RESPIRATION, PREFERABLY MOUTH-TO-MOUTH. IF BREATHING IS
    DIFFICULT, GIVE OXYGEN. CALL PHYSICIAN. SKIN: FLUSH W/WATER. TREAT
    FOR FROSTB ITE IF NECESSARY. EYE: IMMEDIATELY FLUSH EYES W/PLENTY
    OF WATER. CALL PHYSICIAN. INGESTION: NOT LIKELY TO BE HAZARDOUS BY
    INGESTION: HOWEVER, CONSULT PHYSICIAN IF NECESSARY.

=====================  Fire Fighting Measures  =====================

Flash Point:NR
Extinguishing Media:AS APPROPRIATE FOR COMBUSTIBLES IN AREA.
Fire Fighting Procedures:SELF-CONTAINED BREATHING APPARATUS IS REQUIRED
    IF CYLINDERS RUPTURE AND CONTENTS ARE RELEASED UNDER FIRE
    CONDITIONS.
Unusual Fire/Explosion Hazard:USE WATER SPRAY OR FOG TO COOL
    CONTAINERS. CYLINDERS MAY RUPTURE UNDER FIRE CONDITIONS.
    DECOMPOSITION MAY OCCUR.

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

Spill Release Procedures:VENTILATE AREA-ESPECIALLY LOW PLACES WHERE
    HEAVY VAPORS MIGHT COLLECT. REMOVE OPEN FLAMES. USE SCBA FOR LARGE
    SPILLS.

======================	Handling and Storage  ======================

Handling and Storage Precautions:AVOID BREATHING VAPORS AND LIQUID
    CONTACT WITH SKIN OR EYES. USE ONLY IN WELL-VENTILATED AREA.
Other Precautions:STORE IN A CLEAN, DRY AREA. DO NOT HEAT ABOVE 125 F.

=============  Exposure Controls/Personal Protection  =============

Respiratory Protection:NORMAL VENTILATION FOR STANDARD MANUFACTURING
    PROCEDURES IS GENERALLY ADEQUATE. SELF-CONTAINED BREATHING
    APPARATUS IS REQUIRED IF A LARGE RELEASE OCCURS.
Ventilation:LOCAL EXHAUST SHOULD BE USED WHEN LARGE AMOUNTS ARE
    RELEASED. MECHANICAL VENTILATION SHOULD BE USED IN LOW PLACES.
Protective Gloves:LINED BUTYL GLOVES
Eye Protection:CHEMICAL SPLASH GOGGLES
