SECTION 3: Hazards Identification
Emergency Overview:	Irritating to skin, eyes and respiratory tract. Toxic if swallowed. Harmful in contact with skin.
Primary Routes of Exposure:	Ingestion, inhalation of dust and vapor. Skin.
Eye Contact:	Causes moderate to severe irritation of the eyes.
Skin Contact:	Harmful in contact with skin. Causes moderate to severe irritation of the skin.
Inhalation:	(As dust or dimethylamine vapor) Acutely irritating to the nose, mucous membranes and respiratory tract.
Ingestion:	Toxic. Ingestion may lead to dizziness, abdominal cramps, vomiting, bloody diarrhea, weakness, and convulsions.
Acute Health Effects:	Irritating to skin, eyes and respiratory tract. Dimethylamine is toxic and corrosive if swallowed, inhaled, or absorbed through skin.
Chronic Health Effects:	Animal studies: Possible tumorigen. Dimethylamine: mutagen.
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 soap and 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:	110°F
Autoignition Temperature:	no data
Explosion Limits:	no data
Extinguishing Medium:	Water, carbon dioxide, dry powder or foam.
Special Fire Fighting Procedures:	If involved in a fire, fire fighters should be equipped with a 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 emit toxic organic vapors and mildly irritating boric acid fumes.
Unusual Fire or Explosion Hazards:	Highly flammable solid. Heat will liquefy product which over 34�C may decompose to flammable hydrogen and dimethylamine gas.

SECTION 6: Accidental Release Measures
Spill and Leak Procedures:	Eliminate all ignition sources. Avoid raising 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:	To avoid pressure increase due to slow decomposition, store in a tightly sealed container below 25 �C in a temperature controlled area. Open carefully. Handle under inert gas.

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 appropriate chemical resistant gloves and protective clothing.
Ventilation:	Material may form a fine dust. If possible, handle the material in an efficient fume hood.
Respirator:	If a fine dust is raised and ventilation is not available a respirator should be worn. The use of respirators requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134.
Additional Protection:	No additional protection required.
