Aggravation of Pre-existing Conditions: The use of alcoholic beverages enhances the toxic effects.
========================================================================
FIRST AID MEASURES
========================================================================
Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen.
Call a physician.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an
unconscious person. Get medical attention.
Skin Contact:
Remove any contaminated clothing. Wash skin with soap or mild detergent and water for at least 15
minutes. Get medical attention if irritation develops or persists.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids
occasionally. Get medical attention immediately.
========================================================================
PREVENTATIVE MEASURES
========================================================================
Airborne Exposure Limits: None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as
possible. Local exhaust ventilation is generally preferred because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work area. Please refer to the
ACGIH document, "Industrial Ventilation, A Manual of Recommended Practices", most recent edition,
for details.
Personal Respirators (NIOSH Approved):
For conditions of use where exposure to the substance is apparent, consult an industrial hygienist. For
emergencies, or instances where the exposure levels are not known, use a full-facepiece positive-
pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in
oxygen-deficient atmospheres.

Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash
fountain and quick-drench facilities in work area.
Handling and Storage:
Protect against physical damage. Outside or detached storage is preferred. Inside storage should be in a
standard flammable liquids storage room or cabinet. Separate from oxidizing materials. Storage and use
areas should be No Smoking areas. Containers of this material may be hazardous when empty since they
retain product residues (vapors, liquid); observe all warnings and precautions listed for the product.

ENVIRONMENTAL PROTECTION DATA
========================================================================
Accidental Release Measures:
Ventilate area of leak or spill. Remove all sources of ignition. Wear appropriate personal protective
equipment. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and
recover liquid when possible. Use non-sparking tools and equipment. Collect liquid in an appropriate
container or absorb with an inert material (e. G., vermiculite, dry sand, earth), and place in a chemical
waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer!
Disposal Considerations:
Whatever cannot be saved for recovery or recycling should be managed in an appropriate and approved
waste disposal facility. Processing, use or contamination of this product may change the waste
management options. State and local disposal regulations may differ from federal disposal regulations.
