If unconscious, place in recovery position and seek medical advice. Keep respiratory tract clear. In case of skin contact : If symptoms persist, call a physician. Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficulty. In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash contaminated clothing before re-use. If on skin, rinse well with water. If on clothes, remove clothes. In case of eye contact : Small amounts splashed into eyes can cause irreversible tissue damage and blindness. In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Continue rinsing eyes during transport to hospital. Remove contact lenses. Protect unharmed eye. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist. If swallowed : Call a physician immediately. Rinse mouth thoroughly with water. Keep respiratory tract clear. Do NOT induce vomiting. If symptoms persist, call a physician. Most important symptoms and effects, both acute and delayed : Harmful if swallowed. Causes serious eye damage. Suspected of damaging fertility or the unborn child. Causes severe burns. Protection of first-aiders : First Aid responders should pay attention to self-protection and use the recommended protective clothing SAFETY DATA SHEET according to the OSHA Hazard Communication Standard NOROX MEC Version 1.3 Revision Date: 04/22/2024 SDS Number: 600000000092 Date of last issue: 06/24/2022 Date of first issue: 10/19/2018 5 / 32 Notes to physician : Treat symptomatically and supportively. SECTION 5. FIRE-FIGHTING MEASURES Suitable extinguishing media : Water spray jet Alcohol-resistant foam Carbon dioxide (CO2) Dry chemical Unsuitable extinguishing media : High volume water jet Specific hazards during fire fighting : Risk of explosion if heated under confinement. Possible emission of gaseous decomposition products may lead to a dangerous pressure build-up. Avoid confinement. Contact with incompatible materials or exposure to temperatures exceeding SADT may result in a self- accelerating decomposition reaction with release of flammable vapors which may auto-ignite. The product burns violently. Flash back possible over considerable distance. Do not allow run-off from fire fighting to enter drains or water courses. Vapors may form explosive mixtures with air. Cool closed containers exposed to fire with water spray. Specific extinguishing meth- ods : Do not use a solid water stream as it may scatter and spread fire. Remove undamaged containers from fire area if it is safe to do so. Use water spray to cool unopened containers. Further information : Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Use a water spray to cool fully closed containers. 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. Special protective equipment for fire-fighters : Wear self-contained breathing apparatus for firefighting if necessary. Use personal protective equipment. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protec- tive equipment and emer- : Follow safe handling advice and personal protective equipment recommendations. SAFETY DATA SHEET according to the OSHA Hazard Communication Standard NOROX MEC Version 1.3 Revision Date: 04/22/2024 SDS Number: 600000000092 Date of last issue: 06/24/2022 Date of first issue: 10/19/2018 6 / 32 gency procedures Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Use personal protective equipment. Ensure adequate ventilation. Remove all sources of ignition. Never return spills in original containers for re-use. Treat recovered material as described in the section "Disposal considerations". Environmental precautions : 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 : Contact with incompatible substances can cause decomposition at or below SADT. Clear spills immediately. Suppress (knock down) gases/vapors/mists with a water spray jet. To clean the floor and all objects contaminated by this material, use plenty of water. Soak up with inert absorbent material. Isolate waste and do not reuse. Non-sparking tools should be used. Local or national regulations may apply to releases and disposal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which regulations are applicable. SECTION 7. HANDLING AND STORAGE Technical measures : See Engineering measures under EXPOSURE CONTROLS/PERSONAL PROTECTION section. Advice on protection against fire and explosion : Take necessary action to avoid static electricity discharge (which might cause ignition of organic vapors). Keep away from heat and sources of ignition. Use only explosion-proof equipment. Keep away from open flames, hot surfaces and sources of ignition. Keep away from combustible material. Do not spray on a naked flame or any incandescent material. Advice on safe handling : Open drum carefully as content may be under pressure. Protect from contamination. Do not swallow. Do not breathe vapors/dust. Avoid exposure - obtain special instructions before use. Avoid contact with skin and eyes. Avoid formation of aerosol.

SECTION 5. FIRE-FIGHTING MEASURES Suitable extinguishing media : Water spray jet Alcohol-resistant foam SAFETY DATA SHEET BENOX L-40LV Version 4.0 Revision Date: 08/09/2021 SDS Number: 600000000152 Date of last issue: 12/04/2019 Date of first issue: 06/27/2017 4 / 20 Carbon dioxide (CO2) Dry chemical Unsuitable extinguishing media : High volume water jet Specific hazards during fire fighting : Contact with incompatible materials or exposure to temperatures exceeding SADT may result in a self- accelerating decomposition reaction with release of flammable vapors which may auto-ignite. The product burns violently. Flash back possible over considerable distance. Vapors may form explosive mixtures with air. The product will float on water and can be reignited on surface water. Cool closed containers exposed to fire with water spray. Specific extinguishing meth- ods : Do not use a solid water stream as it may scatter and spread fire. Remove undamaged containers from fire area if it is safe to do so. Use water spray to cool unopened containers. Further information : 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. Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Special protective equipment for fire-fighters : Wear self-contained breathing apparatus for firefighting if necessary. Use personal protective equipment. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protec- tive equipment and emer- gency procedures : Use personal protective equipment. Remove all sources of ignition. Follow safe handling advice and personal protective equipment recommendations. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Never return spills in original containers for re-use. Treat recovered material as described in the section "Disposal considerations". Environmental precautions : 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.
