Tri-2-propanolamine Tris(2-hydroxypropyl)amine 1,1',1"-Nitrilotripropan-2-ol

CAS #: 122-20-3

UN #: 3259

EC Number: 204-528-4

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust. Prevent build-up of electrostatic charges (e.g., by grounding).	Use water spray, powder, foam, carbon dioxide.


	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Sore throat. Cough. Burning sensation. Shortness of breath.	Use breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	Redness.	Protective gloves.	Rinse skin with plenty of water or shower.
Eyes	Redness. Pain. Burns.	Wear safety goggles.	Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer immediately for medical attention.
Ingestion	Sore throat. Burning sensation.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Remove all ignition sources. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.	According to UN GHS Criteria WARNING Causes serious eye irritation Causes skin irritation May cause respiratory irritation Transportation UN Classification UN Hazard Class: 8; UN Pack Group: II
STORAGE
Separated from strong oxidants, strong acids and food and feedstuffs. Dry.
PACKAGING
Do not transport with food and feedstuffs.

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance WHITE HYGROSCOPIC CRYSTALS. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers Decomposes on burning. This produces toxic fumes including nitrogen oxides. The solution in water is a medium strong base. Reacts with strong oxidants and strong acids.	Formula: C₉H₂₁NO₃ / (CH₃CHOHCH₂)₃N Molecular mass: 191.3 Boiling point: 305°C Melting point: 45°C Density: 1.0 g/cm³ Solubility in water, g/100ml at 20°C: 83 (good) Vapour pressure at 20°C: negligible Relative vapour density (air = 1): 6.6 Flash point: 160°C o.c. Auto-ignition temperature: 320°C Explosive limits, vol% in air: 0.8-5.8 Octanol/water partition coefficient as log Pow: -1.2
