tetrabutylammonium 2-amino-6-iodopurinate

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Not considered to be a direct inhalation hazard, but if dust

is inhaled, move to area of fresh air and give artificial

respiration if breathing has stopped.  If there are signs of

discomfort, seek medical advice.  Show copy of safety data

sheet or label to medical staff.

(Note:  if in contact with dust, ensure that eyes and skin

are suitably cleaned as appropriate)

Emergency measure - Eyes: Rinse immediately with large volumes of water for 10 - 15

minutes.  Seek medical attention.  Show copy of safety data

sheet or label to the medical staff.

Emergency measure - Skin: Wash with water and mild soap or detergent.  If signs of

discomfort arise, seek medical attention.  Remove

contaminated clothing and wash thoroughly before re-use.

Emergency measure - Ingestion: If subject is conscious, rinse mouth thoroughly and then

drink plenty of water.  If signs of discomfort arise, seek

medical advice.  Show copy of safety data sheet or label to

medical staff.

Fire-fighting measures

Recommended extinguishing agent: Dry foam, powder, water spray, carbon dioxide and other

extinguishing agents.  No adverse reaction with normal

extinguishing agents is known.

Product arising from burning: Complete combustion will lead to the formation of oxides of

carbon, nitrogen, hydrogen iodide and iodine gas.

Product determined by test: N

Protective equipment: Full protective equipment including self-contained breathing

apparatus, suitable gloves, goggles and face protection must

be worn.

Accidental release measures

Emergency measures in case of spillage: Collect material whilst minimising dust generation (through

use of damp mop or other cleaning equipment), place in a

suitably labelled container and dispose of in accordance

with local regulations.  Residues and minor spills may be

washed with water to process sewer, if allowable under

national or local regulations.

Personal protective equipment (PPE) including respirator,

suitable gloves and eye protection should be worn.

Handling and storage

Handling: As the substance exists in the dry form, precautions should

be taken to reduce the possibility of dust formation.

Suitable ventilation should be applied to the working area.

When physical or engineering controls are not sufficient to

control dust exposure, approved respiratory equipment to

EN136 standard should be worn.  For manufacturing areas,

coveralls, gowns or other impervious material together with

neoprene, rubber or other suitable gloves which are

impervious to the processing materials should be worn.

Chemical safey glasses to BS 2092 or equivalent should be

worn if a full respirator is not being worn.

Storage: Store dry under ambient conditions in sealed, upright fibre

drums and ensure containers are correctly labelled.

Packaging of the substance and or preparation: UN approved fibre drums.

Disposal considerations

Industry - Possibility of recovery/recycling: The substance is consumed during use and there is no

opportunity for recovery or recycling once used.

Industry - Possibility of neutralisation: No method of chemical neutralisation is known.

Industry - Possibility of destruction: controlled discharge: Trace quantities can be destroyed by biological oxidation in

the waste water treatment plant.

Code A641

Industry - Possibility of destruction - incineration: Large quantities are destroyed by incineration.  A

closed-cycle incinerator with scrubbers should be employed.

Code A663

Industry - Possibility of destruction - water purification: Trace quantities of material in aqueous washes and in mother

liquors will be treated in a secondary biological waste

water plant before discharge to a municipal treatment plant.

Industry - Possibility of destruction - other: None.

Public at large - Possibility of recovery/recycling: Not applicable as the substance will not enter the public

domain.

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: Not applicable.
