Guidance on Safe Use
Administrative data
First-aid measures
Emergency measure - Eyes: Rinse immediately with plenty of water and seek medical
advice (show the safety data sheet if possible).
Emergency measure - Skin: Wash with plenty of water
Emergency measure - Ingestion: Seek medical attention.
Fire-fighting measures
Recommended extinguishing agent: Combustion products may contain carbon, nitrogen and
sulphur oxides together with some soot. Suitable
extinguishing agents are water and foam.
Accidental release measures
Emergency measures in case of spillage: Wear protective clothing, collect spill by mechanical means
and place in labelled containers. Contaminated product must
be destroyed by incineration. Prevent the substance from
entering drainage systems.
Handling and storage
Handling: Avoid exposure. Ensure filling places have efficient local
exhaust ventilation (air must be filtered) A dust mask,
gloves and eye protection should be used (as minimum
protection). Use only when desensitised. If necessary, wear
a full face mask respirator.
Storage: Store in closed but not sealed containers under cool
conditions.

Stability and reactivity
Danger other than fire: No reaction with water. However, in aqueous solution the
substance is light sensitive and decomposes to nitrogen,
phenol and salicylic acid.
Disposal considerations
Industry - Possibility of recovery/recycling: The substance cannot be recycled
Industry - Possibility of neutralisation: The explosive properties may be removed by desensitisation.
The other hazardous properties may be removed by photolysis
of aqueous solutions.
Industry - Possibility of destruction: controlled discharge: Not recommended
Industry - Possibility of destruction - incineration: Recommended method, waste gas treatment to remove sulphur
and nitrogen oxides should be used.
Industry - Possibility of destruction - water purification: Not recommended
Public at large - Possibility of recovery/recycling: Recovery from coated paper is not possible.
Public at large - Possibility of neutralisation: Not applicable at concentration used (95% of substance
decomposed by developer, 5% forms an azo dye).
Public at large - Possibility of destruction: controlled discharge: Paper containing the substance maybe disposed of as
household waste.
