Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: If inhaled, remove from area to fresh air. Get medical

attention if respiratory irritation develops or if breathing

becomes difficult.

Emergency measure - Eyes: In case of contact, immediately flush eyes with plenty of

water for at least 15 minutes. Get medical attention.

Emergency measure - Skin: In case of contact, wash skin immediately with plenty of

soap and water for at least 15 minutes. Get medical

attention if irritation persists.

Emergency measure - Ingestion: Get medical attention.

Fire-fighting measures

Recommended extinguishing agent: Water spray, carbon dioxide, dry chemical powder or foam.

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

fire, evolving noxious fumes (eg carbon and sulfur oxides,

and hydrogen sulfide).

Product determined by test: N

Protective equipment: Full protective clothing and self-contained breathing

apparatus must be worn.

Fight the fire from a safe distance or protected location.

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.

Immediately evacuate the area. Provide maximum ventilation.

Unprotected personnel should move upwind of spill. Only

personnel equipped with proper respiratory and eye/skin

protection should be permitted in the area. Dike area to

contain spill. Take precautions as necessary to prevent

contamination of ground and surface waters. Recover spilled

material on adsorbents, such as sawdust or vermiculite, and

sweep into closed containers for disposal. After all visible

traces have been removed, thoroughly wet vacuum the area.

Dispose of waste material in accordance with local

regulations. Incineration is the preferred method of

disposal.

Handling and storage

Handling: The substance should be stored, handled and used under

conditions of good industrial hygiene and in conformity with

any local regulations in order to avoid exposure.

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 EN374. Lined rubber

gloves or thick nitrile gloves are recommended, as other

kinds of glove showed breakthrough in a test.

Chemical protective clothing to Standard EN368 (nitrile or

butyl rubber).

Eye protection to Standard EN166.

Furthermore, when respiratory protective equipment has to be

used, it must be capable of adequately controlling exposure,

be suitable for the purpose, and conform to the appropriate

international or national standards, such as a vapour mask

conforming to EN405 FF A1.

These measures should be regarded as a minimum.

Storage: Store only in properly labelled containers in a cool, dry,

well ventilated place.

Keep containers tightly closed when not in use.

Store away from strong oxidising agents.

Packaging of the substance and or preparation: 200 kg plastic drums.

SpecialProvisions

Stability and reactivity

Danger other than fire: Incompatible with ketones, aldehydes, olefins and oxidising

materials.

Chemical reaction with water: None which is hazardous. However, the substance is unstable

in aqueous media.

Dust explosion: Not applicable to a liquid.

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 or landfill. In principle, it

may be possible to recover larger spillages of

uncontaminated material for subsequent use.

Industry - Possibility of neutralisation: The notification tests have shown that the substance is

acutely and chronically harmful by ingestion, an eye

irritant and a skin sensitiser. The cause for concern over a

positive in vitro chromosome aberration is mitigated by

negative Ames and in vivo mouse micronucleus tests.

No chemical treatment is practicable to neutralise the

hazardous health properties.

The substance is not classified as dangerous for the

environment.

Industry - Possibility of destruction: controlled discharge: Contaminated containers or spillages of solutions mixed with

inert material (eg sand or soil) may be disposed of by

landfill at an authorised tip in accordance with local

regulations.

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

substance can 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 and

sulfur oxides and hydrogen sulfide) could be formed.

Industry - Possibility of destruction - water purification: The substance should not normally be discharged directly to

the sewage system or the aqueous environment. However,

adverse effects on sewage treatment systems would be

unlikely.

Industry - Possibility of destruction - other: None.

Public at large - Possibility of recovery/recycling: The substance will not enter the public domain.
