sodium (Z)-3-chloro-3-(4-chlorophenyl)-1-hydroxy-2-propene-1-sulfonate

Guidance on Safe Use

First-aid measures

Emergency measure - Inhalation: Remove to fresh air. Symptomatic treatment.

Emergency measure - Eyes: Rinse immediately with lots of water for at least 15

minutes. Seek medical attention.

Emergency measure - Skin: Wash with soap and plenty of water. Seek medical attention

if irritation persists.

Emergency measure - Ingestion: Symptomatic treatment. Seek medical attention if patient

feels unwell.

Fire-fighting measures

Recommended extinguishing agent: water spray, carbon dioxide, dry powder, foam, sand.

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

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

chlorine and sodium-containing compounds).

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.

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 substance containers.

Clean the spillage area with detergent and water. Do not

discharge to drain.

Dispose of waste material in accordance with local

regulations by incineration.

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 by skin and

eye contact, ingestion and inhalation.

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 protective clothing to Standard EN368

Eye protection to Standard prEN166.

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 dust mask

conforming to EN149 FFP1.

Storage: Store at ambient temperature in dry, dark conditions.

Keep containers tightly closed when not in use.

Packaging of the substance and or preparation: UN-approved 100 litre fibreboard drums with inner plastic

bags.

SpecialProvisions

Stability and reactivity

Danger other than fire: None known.

Chemical reaction with water: None.

Dust explosion: No data is available but it can be assumed that the

substance is sensitive to dust explosion when small

particles are mixed with an oxygen-containing atmosphere.

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 shown that the substance is a

skin irritant, skin sensitiser and a severe eye irritant.

There is also a mutagenicity concern. It is also potentially

bioaccumulative and is acutely very toxic to aquatic

organisms.

No chemical treatment is practicable to neutralise the

hazardous health properties.

The potential dust explosion hazard will be neutralised by

appropriate handling and storage measures.

No chemical treatment is practicable to neutralise the

hazardous environmental properties. The substance hydrolyses

spontaneously in water, however, and the hydrolysis product,

chloro-zimtaldehyde is considered to be unstable in aqueous

media in alkaline, and perhaps also neutral, conditions.

Industry - Possibility of destruction: controlled discharge: Disposal by landfill is not recommended unless suitable

effective physico-chemical treatment is conducted first to

reduce the hazardous effects of the substance to within

allowed discharge parameters.

Industry - Possibility of destruction - incineration: The substance should 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 sulphur oxides and chlorine and sodium-containing

compounds) 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.

The substance is unstable in aqueous media, and the

hydrolysis product, chloro-zimtaldehyde, is also considered

to be unstable under alkali, and perhaps also neutral,

aqueous conditions.

Public at large - Possibility of recovery/recycling: Not applicable as the substance will not be made available

to the public.

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.
