Guidance on Safe Use

First-aid measures

Description of first aid measures

General advice

Take off contaminated clothing and shoes immediately.

Inhalation

Remove to fresh air. Oxygen, if needed.

Skin contact

Wash off immediately with soap and plenty of water.

Eye contact

Rinse immediately with plenty of water for at least 15 minutes. If eye irritation persists, consult a specialist.

Ingestion

Rinse mouth. If conscious, give the victim plenty of water to drink. Induce vomiting if person is conscious. Hold person's head low, to prevent aspiration (inhalation into the windpipe) In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible).

Most important symptoms and effects, both acute and delayed

Lungs

Cough

Eyes

Inflammation

Skin

May cause sensitisation by skin contact.

Oral

Symptoms of overexposure may be headache, dizziness, tiredness, nausea and vomiting.

Indication of any immediate medical attention and special treatment needed

This ester can cause moderately serious poisoning effects.

Elimination is therefore the main aim of treatment.

Due to its non-corrosive nature, elimination can be achieved through immediate vomiting or irrigation

of the stomach if the chemical is ingested. It is helpful to give the person powdered carbon afterwards.

Take preventive measures against aspiration (intubation if necessary).

Irritated areas of skin can be treated with corticosteroids.

Corticosteroids are effective following inhalation too.

Treat symptomatically.

Fire-fighting measures

Extinguishing media

Foam

Carbon dioxide (CO2)

Special hazards arising from the substance or mixture

Hazardous decomposition products formed under fire conditions.

Sulphur oxides

Carbon monoxide

Advice for firefighters

Special protective equipment for firefighters

In the event of fire, wear self-contained breathing apparatus.

Use personal protective equipment.

Additional advice

Prevent fire extinguishing water from contaminating surface water or the ground water system.

Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local

regulations.

Use water spray to cool unopened containers

Handling and storage

Precautions for safe handling

Advice on safe handling : Limiting of employee, who are or who could exposed to this

dangerous substance

Limiting the mass of this dangerous substance at the place of

work on a required quantity

Periodical check, minimum three years, of effectivity an function of technical safty precautions.

: Use only in closed systems.

Before a closed system is opened, purching and washing the

system are applied.

Exposure controls

Handle and open container with care.

Ventilate the area.

Use only in area provided with appropriate exhaust ventilation.

Avoid contact with skin and eyes.

Ensure that eye flushing systems and safety showers are

located close to the working place.

Only trained and authorised personnel is allowed to handle

the substance.

Document substance-handling procedures. Superwise handling by site operator.

Advice on protection against

fire and explosion

: Keep away from heat and sources of ignition.

To avoid thermal decomposition, do not overheat.

Conditions for safe storage, including any incompatibilities

Requirements for storage

areas and containers

: Keep container tightly closed in a dry and well-ventilated

place.

Store at room temperature in the original container.

Use PTFE seals.

Containers of precious steel (316), polyethylene, polypropylene.

Exposure controls / personal protection

Engineering measures

Use only in area provided with appropriate exhaust ventilation.

Occupational exposure controls

Personal protective equipment

Respiratory protection : This should be achieved by a good general extraction and -if

practically feasible- by the use of a local exhaust ventilation.

Hand protection : Protective gloves

Butyl-rubber / Layer thickness 0,6 - 0,8 mm / Break through

time > 480 min (level 6) / EN 374

Polychloroprene / Layer thickness 0,5 - 0,7 mm / Break

through time > 480 min (level 6) / EN 374-3

Nitrile latex / Layer thickness 0,4 mm / Break through time >

480 min (level 6) / EN 374

General recommendation: the usage time for protective

gloves is approx. 50% of the breakthrough time measured in

the laboratory.

Eye protection : Wear eye/face protection.

Tightly fitting safety goggles

Skin and body protection

: Wear closed work/protective clothing. When working outside a

closed system, additionally put on aprons made of polyethylene (PE).
