SECTION 3: Hazards Identification
Emergency Overview:	The dust may irritate the skin, eyes, and respiratory system. Moisture will produce ethanol vapor which may cause drowsiness.
Primary Routes of Exposure:	Inhalation, ingestion, contact with skin and eyes.
Eye Contact:	The dust and ethanol hydrolysis product may cause moderate irritation of the eyes.
Skin Contact:	Solid may cause mild irritation of the skin.
Inhalation:	Dust may cause moderate irritation to the upper respiratory tract. Ethanol vapor may cause dizziness and drowsiness
Ingestion:	Ingestion may cause gastrointestinal distress, nausea, vomiting and headache.
Acute Health Effects:	May be irritating to skin, eyes and respiratory tract. Exposure may cause impairment of coordination and reaction time.
Chronic Health Effects:	No data is available for this product. Prolonged exposure to ethanol vapors may be harmful to nerves and liver.
NTP:	No
IARC:	No
OSHA:	No

SECTION 4: First Aid Measures
Eye Exposure:	Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention.
Skin Exposure:	Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists.
Inhalation:	Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing or pain. In such cases seek immediate medical assistance.
Ingestion:	Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel.

SECTION 5: Fire Fighting Measures
Flash Point:	no data
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	carbon dioxide, dry powder or foam.
Special Fire Fighting Procedures:	If involved in a fire, fire fighters should be equipped with NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing.
Hazardous Combustion and Decomposion Products:	If involved in a fire this material may release toxic fumes.
Unusual Fire or Explosion Hazards:	Flammable solid. Formation of explosive air/solid mixtures is possible.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	Eliminate all ignition sources. Do not raise dust. Small spills may be adsorbed into diatomaceous earth, sand, or other suitable adsorbent, and swept up.

SECTION 7: Handling and Storage
Handling and Storage:	Store in a tightly sealed container in a dry place. If container is left open, product may adsorb moisture from the atmosphere and release ethanol vapor.

SECTION 8: Exposure Controls and Personal Protection
Eye Protection:	Always wear approved safety glasses when handling a chemical substance in the laboratory.
Skin Protection:	Wear protective clothing and gloves. Consult with glove manufacturer to determine the proper type of glove.
Ventilation:	Material may form a fine dust. If possible, handle the material in an efficient fume hood.
Respirator:	If ventilation is not available a respirator should be worn. The use of respirators requires a Respiratory Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	No additional protection required.
