Potassium μ-fluoro-bis(triethylaluminate)

Guidance on Safe Use

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).

SpecialProvisions

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.
