Safety Data Sheet PHOSPHORIC ACID 75% Version Revision Date: 02/11/2020 SDS Number: 100000054299 3 / 12 PHOSPHORIC ACID 75% SECTION 4. FIRST AID MEASURES General advice : Move out of dangerous area. Consult a physician. Show this Safety data Sheet to the doctor in attendance. Do not leave the victim unattended. If inhaled : If unconscious, place in recovery position and seek medical advice. If symptoms persist, call a physician. In case of skin contact : Immediate medical treatment is necessary as untreated wounds from corrosion of the skin heal slowly and with difficul-ty. Take victim immediately to hospital.

5 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 tis-sue 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. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist. Take victim immediately to hospital. If swallowed : Clean mouth with water and drink afterwards plenty of water. Keep respiratory tract clear. Do NOT induce vomiting. Never give anything by mouth to an unconscious person. If symptoms persist, call a physician. Take victim immediately to hospital. SECTION 5. FIREFIGHTING MEASURES Suitable extinguishing media : Dry powder Water may be ineffective. Water mist Unsuitable extinguishing media : High volume water jet Specific hazards during fire-fighting : Do not allow run-off from fire fighting to enter drains or water courses.

6 Hazardous combustion prod-ucts : Phosphorous oxides toxic fumes Specific extinguishing meth-ods : Collect contaminated fire extinguishing water separately. This must not be discharged into drains. Use water spray to cool unopened containers. Safety Data Sheet PHOSPHORIC ACID 75% Version Revision Date: 02/11/2020 SDS Number: 100000054299 4 / 12 PHOSPHORIC ACID 75% Further information : Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations. Special protective equipment for firefighters : Wear self-contained breathing apparatus for firefighting if nec-essary. SECTION 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protec-tive equipment and emer-gency procedures : Use personal protective equipment. Environmental precautions : Prevent product from entering drains. Prevent further leakage or spillage if safe to do so.

7 If the product contaminates rivers and lakes or drains inform respective authorities. Methods and materials for containment and cleaning up : Neutralize with chalk, alkali solution or ammonia. Soak up with inert absorbent material ( sand, silica gel, acid binder, universal binder, sawdust). Keep in suitable, closed containers for disposal. SECTION 7. HANDLING AND STORAGE Advice on protection against fire and explosion : Normal measures for preventive fire protection. Advice on safe handling : Do not breathe vapours/dust. Avoid contact with skin and eyes. For personal protection see section 8. Smoking, eating and drinking should be prohibited in the ap-plication area. To avoid spills during handling keep bottle on a metal tray. Dispose of rinse water in accordance with local and national regulations. Conditions for safe storage : Keep container tightly closed in a dry and well-ventilated place.

8 Containers which are opened must be carefully resealed and kept upright to prevent leakage. Observe label precautions. Electrical installations / working materials must comply with the technological Safety standards. Materials to avoid : Do not store near acids. SECTION 8.
