First-aid measures

Emergency measure - Inhalation: The substance will degrade in the atmosphere to form
diethylamine and t-butylamine, which are considered to be
dangerous by inhalation. If vapours are inhaled, move to
area of fresh air. Seek medical advice if difficulty
breathing or if signs of discomfort.
Emergency measure - Eyes: Rinse immediately with plenty of water for at least 15
minutes. Seek medical advice. Show copy of safety sheet to
medical staff.

Treat as for amines
Emergency measure - Skin: Wash with soap and water. Remove contaminated clothing and
wash before re-use. Seek medical advice.
Emergency measure - Ingestion: Seek medical advice.

Fire-fighting measures

Recommended extinguishing agent: Carbon dioxide and chemical foam. The substance is reactive
in water and will react violently forming flammable gas.

Product arising from burning: Complete combustion will lead to carbon dioxide, nitrogen
oxides, water and tantalum oxide. Under confined conditions,
incomplete combustion may lead to the formation of carbon
monoxide and amines.

Product determined by test: N

Protective equipment: Face protection with breathing apparatus, coveralls and
chemical resistant rubber gloves.

Accidental release measures

Emergency measures in case of spillage: Absorb onto sand, paper or other suitable absorbant material
and dispose of as hazardous waste. The area of spill may be
washed with with large quantities of detergent and water if
there is good ventilation and no source of ignition.

Contain area of spill with sandbags or other suitable

Handling and storage

Handling: Protective equipment when handling the substance in bulk or
during transfer prior to use should include suitable
butyl gloves, goggles and protective outer clothing. The
area should have good ventilation or breathing apparatus
should be used.

Precautions should be followed as considered appropriate for
corrosive amines.

Storage: Store cool (< 4°C) in the dark. Avoid exposure to water or

Packaging of the substance and or preparation: Expected to be imported in stainless steel containers with a
volume of approximately 1.2 litres

Stability and reactivity

Danger other than fire: None reported

Chemical reaction with water: Reacts violently with water forming release of diethylamine
and t-butylamine. These alkylamines, which are highly
flammable and corrosive, may be evolved in dangerous

Dust explosion: Not applicable

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: Not possible to recover after use or if spilled. The
substance reacts rapidly in the presence of moist air.

Industry - Possibility of neutralisation: Small amounts can be mixed in a large excess of water
(heeding warnings of exothermic reaction). The degradation
product diethylamine will dissolve in an excess of water and
can be neutralised with weak acid.

The diluted solution is not considered to be dangerous.

Industry - Possibility of destruction: controlled discharge: Not recommended

Industry - Possibility of destruction - incineration: This is recommended for disposal. Waste gas scrubbing to
remove noxious fumes should be used.

Industry - Possibility of destruction - water purification: Not recommended.

Public at large - Possibility of recovery/recycling: Not applicable for the public
