First-aid measures

General measures:

In case of every product contact or possible exposition inform the supervisor and safety officer.

Wait for further instructions.

Inhalation:

Get medical attention if symptoms occur.

If unconscious, place in recovery position and get medical attention immediately.

If not breathing, if breathing is irregular or if respiratory arrest occurs, provide artificial respiration or oxygen by trained personnel.

Move exposed person to fresh air. Keep person warm and at rest.

Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

In case of inhalation of decomposition products in a fire, symptoms may be delayed. The exposed person may need to be  kept under medical surveillance for 48 hours.

Ingestion:

Call a doctor immediately.

Move exposed person to fresh air.

Wash out mouth with water. Keep person warm and at rest.

If material has been swallowed and the exposed person is conscious, give small quantities of water to drink.

Stop if the exposed person feels sick as vomiting may be dangerous.

Never give anything by mouth to an unconscious person.

Do not induce vomiting unless directed to do so by medical personnel.

If vomiting occurs, the head should be kept low so that vomit does not enter the lungs.

If unconscious, place in recovery position and get medical attention immediately.

Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband.

Skin contact:

Get medical attention if symptoms occur.

Flush contaminated skin with plenty of water.

Remove contaminated clothing and shoes.

Wash clothing before reuse. Clean shoes thoroughly before reuse.

Eye contact:

Call a doctor immediately.

Check for and remove any contact lenses.

Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids.

Continue to rinse for at least 10 minutes.

Protect unharmed eye.

Fire-fighting measures

Promptly isolate the scene by removing all persons from the vicinity of the incident if there is a fire.

No action shall be taken involving any personal risk or without suitable training.

Special protective equipment for fire-fighters:

Fire-fighters should wear appropriate protective equipment and selfcontained breathing apparatus (SCBA) with a full face-piece operated in positive pressure mode.

Extinguishing media:

Suitable: in case of fire, use water spray (fog), foam, dry chemical or CO2.

Not suitable: none known

Special hazards caused by the substance: no specific fire or explosion hazard.

Hazardous combustion products:

In case of fire, the following can be released:

nitrogen oxides (NOx)

carbon monoxide (CO)

sulphur dioxide (SO2)

toxic and irritant fumes and dust

Combustion gases of organic materials must in principle be classified as inhalation poisons.

Accidental release measures

Personal precautions:

No action shall be taken involving any personal risk or without suitable training.

Keep unnecessary and unprotected personnel from entering.

Provide adequate ventilation. Put on appropriate personal protective equipment.

Environmental precautions:

Avoid dispersal of spilled material and runoff or contact with soil, waterways, drains and sewers.

Inform the relevant authorities if the  product has caused environmental pollution (sewers, waterways, soil or air).

Large spill:

Move containers from spill area. Prevent entry into sewers, water courses, basements or confined areas.

Vacuum or sweep up material and place in a designated, labelled waste container. Dispose of via a licensed waste disposal contractor.

Note: see section  1of MSDS for emergency contact information and section 13 for waste disposal.

Small spill:

Move containers from spill area. Vacuum or sweep up material and place in a designated, labelled waste container.

Dispose of via a licensed waste disposal contractor.

Handling and storage

Handling:

The product is registered under strictly controlled conditions as defined in Article 17(3) of Regulation (EC) no. 1907/2006  and must therefore be handled as such.

Refer to the industry guidance prepared by ECHA for detailed measures.

The prescribed regulations for work, hygiene and relevant laws must be observed.

Workers should wash hands and face before eating, drinking and smoking.

Do not ingest. Avoid contact with eyes, skin and clothing.

Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use.

Empty containers retain product residue and must be handled as hazardous material.

Storage:

Use appropriate containment to avoid emissions and environmental contamination.

Store under lock and key and with access restricted to technical experts or their assistants only.

Store in accordance with national and local regulations.

Existing storage restrictions with other materials must be adhered.

Recommended storage temperature: room temperature

Store in original container protected from direct sunlight in a dry, cool and well ventilated area, away from incompatible materials and food and drink.

Exposure controls / personal protection

1. Technical protection measures

The substance must be rigorously contained by technical means during its whole lifecycle including manufacture, purification, cleaning and maintenance of equipment, sampling, analysis, loading and unloading of equipment or vessels, waste disposal or purification and storage.

Procedural and control technologies are implemented to minimise emission and any resulting exposure.

2. Organisational protection measures

Only properly trained and authorised personnel shall handle the substance. Proceedures and handling must be well documented.

In the case of cleaning and maintenance works, special procedures such as purging and washing shall be applied before the system is opened and entered.

General protective and hygienic measures:

Ensure that eyewash stations and safety showers are close to the workstation location.

Appropriate techniques should be used to remove potentially contaminated clothing.

Wash contaminated clothing before reusing.

Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period.

Do not inhale dust / smoke / mist.

Avoid contact with the eyes and skin.
