	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	Use water spray, powder, alcohol-resistant foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed. See Notes.	Use local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Pain. Redness. Blisters. Skin burns.	Protective gloves.	First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Refer for medical attention .
Eyes	Pain. Redness. Severe deep burns.	Wear safety goggles or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Burning sensation. Abdominal cramps. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention .

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.	According to UN GHS Criteria Transportation UN Classification
STORAGE
Separated from strong oxidants and strong acids. Dry. Keep in the dark. Well closed.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE HYGROSCOPIC CRYSTALLINE POWDER WITH CHARACTERISTIC ODOUR. TURNS YELLOW ON EXPOSURE TO LIGHT AND AIR. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on heating and on burning. This produces toxic gases of nitrogen oxides. The solution in water is a medium strong base. Reacts with strong acids. Reacts violently with strong oxidants. This generates fire and explosion hazard.	Formula: C₆H₁₅NO₂ / (CH₃CHOHCH₂)₂NH Molecular mass: 133.2 Boiling point: 248°C Melting point: 42°C Relative density (water = 1): 0.99 Solubility in water, g/100ml at 20°C: 87 Vapour pressure, Pa at 42°C: 2.67 Relative vapour density (air = 1): 4.6 Flash point: 127°C o.c. Auto-ignition temperature: 374°C Explosive limits, vol% in air: 1.1-5.4

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of the aerosol may cause lung oedema. See Notes. The effects may be delayed. Medical observation is indicated.

Inhalation risk
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20°C.

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT

NOTES
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
