First-aid measures

General advice

When symptoms persist or in all cases of doubt seek medical advice. If unconscious, place in recovery position and get medical

attention immediately. Show this safety data sheet to the doctor in attendance.

Eye Contact:

Immediately flush with plenty of water. After initial flushing, remove any contact lenses and continue flushing for at least 15

minutes. Get medical attention immediately if symptoms occur.

Skin contact:

Wash off immediately with soap and plenty of water. Remove contaminated clothing and shoes. Get medical attention if irritation

develops and persists. In case of burns, immediately cool affected skin for as long as possible with cold water. For severe burns,

immediate medical attention is required. Wash contaminated clothing before reuse. Discard contaminated shoes.

Ingestion:

If swallowed, rinse mouth with water (only if the person is conscious). Call a physician immediately. Remove victim to fresh air and

keep at rest in a position comfortable for breathing. Loosen tight clothing such as a collar, tie, belt or waistband. Never give

anything by mouth to an unconscious person. Do NOT induce vomiting unless directed to do so by a physician. If vomiting occurs

spontaneously, keep head below hips to prevent aspiration. Maintain an open airway. If not breathing, give artificial respiration. If

breathing is difficult, give oxygen.

Inhalation:

Remove to fresh air. If not breathing give artificial respiration. If breathing is difficult, give oxygen. Call a physician. Keep victim

warm and quiet. Loosen tight clothing such as a collar, tie, belt or waistband. Maintain an open airway. Persons who have inhaled

vapours or smoke fumes have to be put under medical observation for at least 48 hours, due to the delayed appearance of

poisoning.

Protection of first-aiders:

Wear personal protective equipment. Ensure that medical personnel are aware of the material(s) involved and take precautions to

protect themselves.

Notes to physician:

Treat symptomatically. Contact with hot material: Treat for thermal burns. Persons who have inhaled vapours or smoke fumes have

to be put under medical observation for at least 48 hours, due to the delayed appearance of poisoning.

Fire-fighting measures

lasting effects.  Runoff may pollute waterways.

Advice for firefighters

Special protective equipment for fire-fighters:

Positive pressure self-contained breathing apparatus (SCBA) and structural firefighters’ protective clothing will provide adequate

protection.

Special protective actions for fire-fighters:

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

from contaminating surface water or the ground water system. Collect contaminated fire extinguishing water separately. This must

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

regulations. Move containers from fire area if you can do it without risk. Cool containers / tanks with water spray.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:

Advice for non-emergency personnel:

No action shall be taken involving any personal risk or without suitable training. Do not touch or walk through spilled material. Avoid

contact with skin, eyes and clothing. Wear personal protective equipment.

Evacuate personnel to safe areas. Ensure adequate ventilation. Do not touch damaged containers or spilled material unless

wearing appropriate protective clothing. Stop leak if you can do it without risk.

Advice for emergency responders:

Contain and collect spillage with non-combustible absorbent material (e.g. sand, earth, diatomaceous earth, vermiculite) and place

in container for disposal according to local/national regulations (see Section 13). Refer to protective measures listed in sections 7

and 8.

Environmental Precautions:

Prevent further leakage or spillage if safe to do so. Clean up spill immediately. Prevent product and washings from entering drains,

sewers or surface water due to high toxicity to aquatic organisms.

Local authorities should be advised if significant spillages cannot be contained.

Methods and materials for containment and cleaning up:

Methods for Containment:

Prevent further leakage or spillage if safe to do so. Dike to collect large liquid spills. Contain and collect spillage with

non-combustible absorbent material (e.g. sand, earth, diatomaceous earth, vermiculite) and place in container for disposal

according to local/national regulations (see Section 13).

Methods for cleaning up:

Take up with sand or other noncombustable absorbent material and place into containers for later disposal. Clean contaminated

surface thoroughly. Prevent product and washings from entering drains, sewers or surface water due to high toxicity to aquatic

organisms.

Handling and storage

Precautions for safe handling

Advice on safe handling

Do not handle until all safety precautions have been read and understood. Handle product only in closed system or provide

appropriate exhaust ventilation at machinery. Prevent the formation of vapors, mists and aerosols. Do not breathe vapours or spray

mist. Avoid contact with skin, eyes and clothing. Wear personal protective equipment. In case of insufficient ventilation, wear

suitable respiratory equipment. See also section 8.

Consider technical advances and process upgrades (including automation) for the elimination of releases. Minimise exposure

using measures such as closed systems, dedicated facilities and suitable general/local exhaust ventilation. Drain down systems

and clear transfer lines prior to breaking containment. Clean/flush equipment, where possible, prior to maintenance. Where there

is potential for exposure: restrict access to authorised persons; provide specific activity training to operators to minimise exposures;

wear suitable gloves and coveralls to prevent skin contamination; wear respiratory protection when its use is identified for certain

contributing scenarios; clear up spills immediately and dispose of wastes safely. Ensure safe systems of work or equivalent

arrangements are in place to manage risks. Regularly inspect, test and maintain all control measures. Consider the need for

risk-based health surveillance.

Advices on general occupational hygiene

Handle in accordance with good industrial hygiene and safety practice. Ensure that eyewash stations and safety showers are close

to the workstation location. Use personal protection recommended in Section 8. It is a good industrial hygiene practice to minimize

skin contact. Do no eat, drink or smoke when using this product. Wash hands before breaks and at the end of workday. Remove

and wash contaminated clothing before re-use. Keep away from food, drink and animal feeding stuffs.

Conditions for safe storage, including any incompatibilities

Technical measures/Storage conditions

Keep containers tightly closed in a dry, cool and well-ventilated place. Keep away from direct sunlight. Keep away from contact with

oxidizing materials. Keep in properly labelled containers. Use appropriate containment to avoid environmental contamination.

Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Store in accordance with local

regulations.
