Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Eyes: Rinse immediately and for as long as possible with plenty of
water. Eyelids should be held away from the eyeball to
ensure thorough rinsing. Always seek medical advice.
Seek medical attention.
Emergency measure - Skin: Remove all contaminated clothing immediately. Wash off with
plenty of soap and water. Always seek medical advice.
Launder clothes before reuse.
Emergency measure - Ingestion: Rinse mouth. Give water to drink. Do not induce vomiting as
the substance is corrosive. Always seek medical advice.
Fire-fighting measures
Unsuitable extinguishing media: halones.
Product arising from burning: Products of complete combustion are carbon dioxide, water
and boron oxide.
Additionally, products of incomplete combustion may include
carbon monoxide, elemental carbon and hydrocarbons (alkanes
and alkenes).
Product determined by test: N
Protective equipment: Wear self-contained breathing apparatus.
Accidental release measures
protective gloves and boots. For respiratory protection
(with Filter A/P2), wear an approved self-contained
breathing apparatus with full-facepiece, with safety
glasses.
Avoid contact with skin and eyes.
Isolate spill area. After fire has been extinguished or
allowed to burn out completely, wait condiderable time
(until smoke is no longer observed). After that, carefully
wash spill area with a waterspray.
Do not flush into public watear courses.
Handling and storage
lines or opening connections, an aluminised suit should be
worn.
Keep away from sources of ignition - No smoking. Take
precautionary measures against static discharges.
Storage: Keep under dry nitrogen containing less than 10 ppm oxygen.
Keep container tightly closed in a cool place. Keep
container dry. Keep container in a well-ventilated place. Do
not store together with strong alkaline, strong oxidising
agents.
Packaging of the substance and or preparation: Dedicated carbon steel cylinders under nitrogen blanket (10
liter - 1500 liter).

Exposure controls / personal protection
Stability and reactivity
presence of oxygen to produce a variety of boron oxides and
boron alkoxides. This will be accompanied by the generation
of heat.
Chemical reaction with water: DEP-IP is insoluble in water and will react only slowly with
it, unless heated to high temperatures or catalysed with
organic acids or bases. A strong base may saponify the
isopropoxy group giving isopropanol and the corresponding
boron hydroxy salt. Strong acids may cleave the ethyl-boron
bonds. However, boron alkyls are less reactive with water
than other metal (e.g. aluminium or zinc) alkyls.
Dust explosion: Not applicable for liquids.
Dust explosion determined by test: N
Disposal considerations
Industry - Possibility of neutralisation: Alkylboranes can be diluted with an appropriate solvent
(e.g. hexane, heptane or others that do not react with DEB-
IP) and added slowly to an excess of the stirred quenching
agent (destruction liquid, such as a solution of basic
hydrogen peroxide or dilutions of carboxylic acids) in an
inert atmosphere.After acidification, alcohols and boric
acid will be generated.
Alternatively, alkylboranes may be destroyed by reaction
with carboxylic acids. Allowance must made for evolution of
alkanes.
Industry - Possibility of destruction - incineration: Incineration is an acceptable method for disposal of
alkylboranes. Precautions should be taken to ensure complete
combustion and to prevent boranes and other toxic gases
from being emitted.
Incinerate in an appropriate incinerator with flue gas
scrubbing (code 661).
Industry - Possibility of destruction - water purification: See annex 3.
Industry - Possibility of destruction - other: Not applicable.
Public at large - Possibility of recovery/recycling: Not applicable, the substance is not available for the
public at large.
Public at large - Possibility of neutralisation: Not applicable.
Public at large - Possibility of destruction: controlled discharge: Not applicable.
Public at large - Possibility of destruction - incineration: Not applicable.
Public at large - Possibility of destruction - water purification: Not applicable.
Public at large - Possibility of destruction - others: None.
