Guidance on Safe Use

First-aid measures

Description of first aid measures

General advice:

Call a physician immediately. Move out of dangerous area. Do not leave the victim unattended. Show this safety data sheet to the doctor in attendance

If inhaled:

If breathed in, move person into fresh air. If it is suspected that fumes are still present, the rescuer should wear an appropriate mask or self-contained breathing apparatus. 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. Keep respiratory tract clear. Loosen tight clothing such as a collar, tie, belt or waistband. If symptoms persist, call a physician.

In case of skin contact:

Chemical burns must be treated promptly by a physician. Wash off with soap and plenty of water. Continue to rinse for at least 10 minutes. Take off contaminated clothing and shoes immediately. If symptoms persist, call a physician.

In case of eye contact:

Chemical burns must be treated promptly by a physician. Small amounts splashed into eyes can cause irreversible tissue damage and blindness. Immediately flush eyes with plenty of water, occasionally lifting the upper and lower eyelids. Keep eye wide open while rinsing. Continue to rinse for at least 10 minutes. Remove contact lenses. Protect unharmed eye. If eye irritation persists, consult a specialist.

If swallowed:

Chemical burns must be treated promptly by a physician. Rinse mouth with water. Give small amounts of water to drink. DO NOT induce vomiting unless directed to do so by a physician or poison control center. If vomiting occurs, the head should be kept low so that vomit does not enter the lungs. Never give anything by mouth to an unconscious person. If unconscious, place in recovery position and get medical attention immediately. Keep respiratory tract clear. Loosen tight clothing such as a collar, tie, belt or waistband. If symptoms persist, call a physician.

Most important symptoms and effects, both acute and delayed

Risks

Causes serious eye damage. Suspected of causing cancer. Causes severe burns.

Indication of any immediate medical attention and special treatment needed

Treatment:

Treat symptomatically.

Fire-fighting measures

Extinguishing media

Suitable extinguishing media:

Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

Unsuitable extinguishing media:

None known.

Special hazards arising from the substance or mixture

Specific hazards during firefighting:

In a fire or if heated, a pressure increase will occur and the container may burst. Do not allow run-off from fire-fighting to enter drains or water courses.

Hazardous combustion products:

Carbon dioxide (CO2), Carbon monoxide, Oxides of phosphorus

Advice for firefighters

Special protective equipment for firefighters:

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

Further information:

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. Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. Collect contaminated fire extinguishing water separately. This must not be discharged into drains.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Personal precautions:

No action shall be taken involving any personal risk or without suitable training. Keep unnecessary and unprotected personnel from entering. Do not touch or walk through spilt material. Do not breathe vapours, aerosols. Ensure adequate ventilation. In case of inadequate ventilation wear respiratory protection. Use personal protective equipment.

Environmental precautions

Environmental precautions:

Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Prevent product from entering drains. Prevent further leakage or spillage if safe to do so. If the product contaminates rivers and lakes or drains inform respective authorities.

Methods and materials for containment and cleaning up

Methods for cleaning up:

Move containers from spill area. Stop leak if safe to do so. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Keep in suitable, closed containers for disposal. Dispose of wastes in an approved waste disposal facility.

Handling and storage

Precautions for safe handling

Advice on safe handling:

Avoid exposure - obtain special instructions before use. Do not get in eyes or mouth or on skin. Do not breathe vapours or spray mist. Provide sufficient air exchange and/or exhaust in work rooms. Keep in the original container or an approved alternative made from a compatible material, kept tightly closed when not in use. Dispose of rinse water in accordance with local and national regulations.

Advice on protection against fire and explosion:

Normal measures for preventive fire protection.

Hygiene measures:

When using do not eat, drink or smoke. Wash hands before breaks and at the end of workday. Remove contaminated clothing and protective equipment before entering eating areas.

Conditions for safe storage, including any incompatibilities

Requirements for storage areas and containers

Store in accordance with local regulations. Store in original container protected from direct sunlight in a dry, cool and well-ventilated area, away from incompatible materials and food and drink. Keep containers sealed until ready for use. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Electrical installations / working materials must comply with the technological safety standards

Advice on common storage:

Keep away from alkalis.

Further information on storage stability:

No decomposition if stored and applied as directed.
