First-aid measures

Emergency measure - Inhalation: Symptomatic treatment.
Emergency measure - Eyes: Rinse immediately with plenty of water and seek medical
help.
Emergency measure - Skin: Wash with soap and water.
Emergency measure - Ingestion: Drink water or milk and seek medical attention.

Fire-fighting measures

Recommended extinguishing agent: Water, carbon dioxide, foam and dry powder are suitable
extinguishers.

Product arising from burning: Combustion products may contain carbon and nitrogen oxides.

Product determined by test: N

Accidental release measures

Emergency measures in case of spillage: The substance will be transported, stored and handled as an
aqueous solution. In case of leaks, contain and recover the
spillage. If this is unsuccessful, it should be washed away
thoroughly with water.

Handling and storage

Handling: Wear eye protection

Storage: Store in a closed container made of an alkali resistant
material (eg stainless steel, plastic, PVC). Contact with a
chelating agent (eg zinc, tin, aluminium etc.) should be
avoided.

Packaging of the substance and or preparation: Not given, 6th amendment notification.

Stability and reactivity

Danger other than fire: DIDA is normally imported as a 47% aqueous solution and as
such has a pH of 12.5.

Chemical reaction with water: None reported.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: DIDA may be recovered from aqueous solutions by using
ethanol as a precipitating medium.

Industry - Possibility of neutralisation: The aqueous solution of DIDA can be neutralised using
mineral acid.

Industry - Possibility of destruction: controlled discharge: The substance can be discharged diluted in waste water but
large volumes should not be discharged to sewage treatment
plants or surface waters as the substance does not
biodegrade and mobilisation of metals in sediments may
occur.

Industry - Possibility of destruction - incineration: Following evaporation to remove water, DIDA may be
incinerated in a suitable incinerator.

Industry - Possibility of destruction - water purification: The substance is non-biodegradable and will not be removed
by conventional sewage treatment. High concentrations will
keep metals in solution or mobilise deposited metals.

Public at large - Possibility of recovery/recycling: Recovery from the final product is not possible.

Public at large - Possibility of neutralisation: The substance is partially neutralised in the product
formulation.

Public at large - Possibility of destruction: controlled discharge: Formulations containing the substance may be safely wasted
through domestic sewers.

Public at large - Possibility of destruction - incineration: Not applicable for the public at large.

Public at large - Possibility of destruction - water purification: The substance will not be removed in municipal sewage
treatment processes nor will it have any effect on metal
remobilisation from sludges or river sediments.
