Fire-fighting measures

Recommended extinguishing agent: Carbon dioxide, dry chemical, alcohol and universal foam,

and water spray.

Product arising from burning: Carbon oxides, Sulfonium oxides, hydrogen floride (derived

from the structure).

Product determined by test: N

Protective equipment: Wear proper protective clothing

fire fighters should wear air supplied respirators.

Accidental release measures

Emergency measures in case of spillage: Eliminate all ignition sources.  Sweep up into containers

and seal.  Dispose of material in accordance with government

requirements and ensure conformity to local disposal


Do not wash into sewer or waterways.

Handling and storage

Handling: The preparation containing the substance will only be used

in the IC industry by trained personnel.  Exposure is

minimal.  Inhalation and skin contact are avoided by the use

of impermeable protective gloves and dust masks.  Dust proof

filling apparatus and appropriate ventilation are also used.

Storage: The preparation containing the substance should be kept in

securely closed unbreakable containers.  Keep away from

foodstuffs and sources of ignition.  Store in a cool and

dark place away from humidity.

Do not expose to any UV light sources.

Packaging of the substance and or preparation: The preparation is packed into either one gallon or one

Disposal considerations

Industry - Possibility of recovery/recycling: The substance is used in very small quantities, is a

photoresist and decomposes when used, therefore recycling of

it is not possible.

Any spilled material is not recovered but is disposed of by

incineration or disposal to landfill in accordance with

local regulations.

Industry - Possibility of neutralisation: Not known

Industry - Possibility of destruction: controlled discharge: Contaminated containers or spillages of the preparation

mixed with inert material (e.g. sand or soil) may be

disposed of at an authorised tip in accordance with local


Industry - Possibility of destruction - incineration: Incineration is the preferred method of disposal.  The

preparation may be disposed of by burning under controlled

conditions at a licensed waste treatment processor in

accordance with local regulations.  Stack gases should be

scrubbed as noxious fumes (e.g. carbon dioxide) could be


Industry - Possibility of destruction - water purification: In the unlikely event that the preparation should enter the

water treatment system, contaminated waste water should be

treated by means of flocculation precipitation.  The

precipitated material should then be incinerated.

Industry - Possibility of destruction - other: None known

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