4. FIRST AID MEASURES
Eye Exposure:
Hold eyelids open and flush with a steady, gentle stream of water for at least 15 minutes. Seek immediate medical attention, preferably with an
ophthalmologist. If a physician is not immediately available, eye irrigation should be continued for an additional 15 minutes.
Skin Exposure:
Immediately wipe excess material off skin with a dry cloth then wash with plenty of soap and water for at least 5 minutes. See medical attention if
irritation develops or persists. Remove contaminated clothing and shoes and clean thoroughly before re-use.
Inhalation:
Remove from immediate source of exposure and assure that victim is breathing. If not breathing, administer cardio-pulmonary resuscitation (CPR). If
breathing is difficult, administer oxygen if available. Seek medical attention. Symptoms can be delayed several hours.
Ingestion:
If swallowed, do not induce vomiting. If victim is conscious and alert, give 1-2 glasses of milk or water to drink. Do not give anything by mouth to an
unconscious person. Seek medical attention immediately. Do not leave victim unattended. To prevent aspiration of swallowed product, lay victim onside with head lower than waist. Vomiting may occur spontaneously. If vomiting occurs and the victim is conscious, give additional milk or water tofurther dilute the chemical.
Medical Conditions Possibly Aggravated by Exposure:
Inhalation of product may aggravate existing chromic respiratory problems such as asthma, emphysema or bronchitis. Skin contact may aggravate
existing skin disease.

5. FIRE FIGHTING MEASURESExtinguishing Media:
Special Fire Fighting Procedures:

Use carbon dioxide, dry chemical, or appropriate foam.
Firefighters should wear NIOSH/MSHA approved positive pressure breathing apparatus with full face-piece andfull chemical resistant protective clothing. Dike area to prevent runoff and contamination of water sources.
Dispose of fire control water later. Extreme heat or water contamination may cause closed containers to
explode.

6. ACCIDENTAL RELEASE MEASURES
Personal Protection:
Spill Cleanup:

Wear chemical goggles, body-covering protective clothing, chemical resistant gloves, and rubber boots. Use
NIOSH approved respirator where mist occurs.
Mop up liquid and dispose in accordance with federal, state and local regulations or permits. Flush area withsolvent then water to complete cleanup.

7. HANDLING AND STORAGE
Handling:
Storage:

Avoid contact with eyes, skin and clothing. Avoid breathing vapors. Keep container closed. Promptly clean
residue from closures with cloth and solvent. Promptly clean up spills.
Store at room temperature in a dry, well ventilated area, away from combustible material, and away from ignition
sources. Keep containers closed. Store in clean plastic or steel containers.

Normal ventilation for good working conditions should be used. Keep containers closed. Safety shower andeyewash fountain should be within direct access.
This product is not considered respirable in either the liquid or cured forms. However, if the cured product ispolished, ground or chipped during processing, handling or use, powders may be released as airborne
respirable particles. In these instances, appropriate personal protection equipment and local ventilation controls
must be employed. If exposure limits are exceeded and local ventilation is unavailable, a supplied-air respirator
or a self-contained NIOSH-approved vapor respirator is required.
Wear body-covering protective clothing and gloves.
Wear chemical goggles or face shield.
