First-aid measures

Emergency measure - Inhalation: If fumes are inhaled, remove to fresh air and seek medical
attention. To extinguish fire in clothing, water may be
used.
Emergency measure - Eyes: Rinse with large quantities of water and seek immediate
medical attention.
Emergency measure - Skin: Remove any contaminated clothing, where, due to contact
clothing has caught fire, water sprinklers should be used.
Treat burnt skin as for equivalent heat burns. To remove
from skin, wipe with medicinal paraffin and rinse with
water.
Emergency measure - Ingestion: Seek immediate medical attention.

Fire-fighting measures

Recommended extinguishing agent: For small fires, cover with fire-extinguishing blanket (DIN
14155), dry sand, Vermiculite or carbon
dioxide-extinguisher; for larger fires use dry
"extinguisher powder" (eg dry powdered sodium bicarbonate).
Water or water-containing foams (and for large fires carbon
dioxide) must not be used. Black smoke appears on burning
due to the toluene present but the combustion gases are not
acidic and do not contain fluoride ions. The residue
consists of a chemically inactive solid containing K, Al,
F, and O which with water gives an alkaline solution.

Accidental release measures

Emergency measures in case of spillage: Wear protective clothing (see 2.3.1). Use dry powder
extinguishers and buckets of dry sand. Residues of the
substance should be soaked with lubricating oil before
incineration in the open air. Large quantities of the
substance should be dissolved in paraffin or other mineral
oil before incinerating in the open air. Small quantities
in the laboratory are destroyed by adding to a 25% solution
of isopropanol in dibutyl ether.

Handling and storage

Handling: The substance is supplied in special containers under a
protective gas and should subsequently be handled only
under an inert gas such as argon or nitrogen (but not
carbon dioxide), which should be dry and oxygen-free. On a
small scale,it should be handled at a separate work station
under a hood and behind a safety glass shield; and on a
large scale, in a special room, operating the apparatus
from outside. All workrooms should be well ventilated.
Saturated or aromatic hydrocarbons should be used for
rinsing apparatus and containers. Dry powder sprinklers
should be installed. Protective kit should consist of
flameproof clothing, helmet with visor, gloves with
gauntlets, gaiters and breeches. Clothing should be made of
silicone-rubber impregnated glass-fibre textile or
aluminium-coated asbestos. Respiratory protection should
consist of full-face masks with appropriate air filters.

Storage: To be stored in acid-resistant steel or nickel containers
sealed with "Teflon" (or similar polyfluorocarbon). within
sealed fireproof rooms. It should be stored diluted with
heptane, white spirit, cyclohexane or similar hydrocarbon
solvent under an inert gas (as above).

Stability and reactivity

Danger other than fire: The substance is a colourless liquid which reacts violent
with many compounds particularly water, alcohols, amines
and oxygen (including air, especially if moist). The
reaction with oxygen causes decomposition, producing an
explosive mixture of hydrocarbons etc (see 3.10). Reaction
with water also causes decomposition, producing a similar
explosive mixture as well as aluminium oxide smoke. There
is a danger of pressure increase in closed vessels. An
explosive mixture of olefins can also be produced by
thermal decomposition in sealed containers.

Disposal considerations

Industry - Possibility of recovery/recycling: Technically it is not possible, to recover the notified
product.

Industry - Possibility of neutralisation: In order to reduce the risk of fire, the product should be
thinned to form 10% solutions e.g. with high-boiling
petroleum fractions. For the final disposal of the waste,
the users of the product are advised to return it to the
manufacturers in the prescribed containers<. Small
quantities can be destroyed in the laboratory using 25%
solution of isopropanol in butyl ether or diesel oil.

Industry - Possibility of destruction: controlled discharge: Not recommended.

Industry - Possibility of destruction - incineration: Not recommended for persons not skilled in handling
aluminium alkyls. However, waste solutions from spillages
may be incinerated. Waste material returned to the
manufacturer for incineration will be diluted with paraffin
or mineral oil prior to incineration.

Industry - Possibility of destruction - water purification: Not recommended. Other: The notifier recommends that all
material should be returned to the manufacturer for
disposal by incineration (see above). Waste material should
be returned in bottles embedded in sand or Kieselguhr.

Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
