CHALCONE DYE

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Remove victim to fresh air.  Give artificial respiration if

needed.  Seek immediate medical attention.

Emergency measure - Eyes: Rinse eyes thoroughly with water for at least 15 minutes,

holding the eye lids open to ensure the material is washed

out.  Seek immediate medical attention.

Emergency measure - Skin: Remove contaminated clothing.  Wash contact area thoroughly

with soap and water.  Seek medical attention if irritation

or symptoms of exposure develop.

Launder contaminated clothing before re-use.

Leather articles which cannot be decontaminated, including

shoes, must be destroyed.

Emergency measure - Ingestion: Seek immediate medical attention.

Fire-fighting measures

Recommended extinguishing agent: Use water fog or spray, universal foam or dry chemical

extinguishers.

Product arising from burning: The substance is combustible and will burn if involved in a

fire, evolving noxious fumes (eg carbon oxides)  However,

there is no experimental evidence to support the anticipated

combustion products.

Product determined by test: N

Protective equipment: Full protective clothing and self-contained breathing

apparatus must be worn.

Accidental release measures

Emergency measures in case of spillage: Evacuate personnel from immediate vicinity.

Wear appropriate personal protective equipment conforming to

the relevant national or international standards as

mentioned in section 2.3.10.

Absorb spillages of solutions with a suitable inert material

(eg sand or soil). Carefully transfer the spillage to waste

containers, or use a sealed industrial vacuum machine.

Containers filled with waste material must be labelled in

the same way as the original containers.

Clean the spillage area with water and detergent.

Dispose of waste material by incineration in accordance with

local regulations.

Handling and storage

Handling: The substance should be stored handled and used in

conditions of good industrial hygiene and in conformity with

any local regulations in order to avoid dermal exposure or

exposure by inhalation. During the use of the final product

to produce finished articles, workers will require clean

room apparel suitable for a microelectronics environment in

addition to any personal protective equipment.  These items

may include NIOSH-approved cartridge-type respirators for

organic vapours and dusts, solvent resistant rubber or

polyethylene gloves, lab coats, rubber aprons, goggles and

impact-resistant safety glasses.

Engineering controls are necessary to reduce exposure to the

substance.

When exposure cannot be prevented or adequately controlled

appropriate personal protective equipment should be worn.

Such protective equipment should conform to the appropriate

international or national standards as follows;

Chemical protective gloves to Standard prEN374

Chemical resistant clothing to Standard EN368

Eye protection to Standard prEN166

When necessary appropriate respiratory protection should be

used. e.g.a dust mask conforming to EN149 FFP1.

The standards mentioned above should be regarded as a

minimum.

Storage: Store in a cool dry well-ventilated area away from

incompatible materials.

Keep containers tightly closed when not in use.

Packaging of the substance and or preparation: The preparation will be supplied in litre bottles which are

sealed and then contained in a bag.

Stability and reactivity

Danger other than fire: None reported.

Chemical reaction with water: None reported.

Dust explosion: There is a potential dust explosion hazard from this organic

powder.  This will be controlled by appropriate storage and

handling techniques.  In addition, the substance will only

be supplied in the EU as a component of a liquid

preparation.

Dust explosion determined by test: N

Disposal considerations

Industry - Possibility of recovery/recycling: Discharge to the environment will be minimal. Recovery from

minor spillages or accidental discharge is not economically

or technically feasible, and such waste material will be

disposed of by incineration.

In principle, it may be possible to recover larger spillages

of uncontaminated material for subsequent use.

Industry - Possibility of neutralisation: The notification tests have not provided evidence that the

substance is hazardous to health. Chemical neutralisation is

not applicable.

The potential dust explosion hazard will be controlled by

appropriate storage and handling techniques.

Industry - Possibility of destruction: controlled discharge: There will be no disposal of the substance by landfill.  All

waste material will be incinerated.

Industry - Possibility of destruction - incineration: All waste and spent packaging will be disposed of by

incineration by burning under controlled conditions at a

licensed waste treatment processor in accordance with local

regulations.  Stack gases should be scrubbed, because

noxious fumes (eg carbon oxides) could be formed.

Industry - Possibility of destruction - water purification: For water releases, the control technology is to remove the

dye via a suitable cartridge carbon filtration system for

purification.  The purified waste stream is discharged to

the local water treatment plant while the spent cartridges

are disposed via the licensed solid waste disposal service

for appropriate disposal.

Industry - Possibility of destruction - other: During manufacture of final products, excess materials will

be collected and transferred to a hazardous waste stream.

Resin solutions and other waste liquids are sent to a

licensed incinerator/solvent reclaimer.

Public at large - Possibility of recovery/recycling: Not applicable. 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.
