FIRST AID MEASURES General advice : Move out of dangerous area. Show this material safety data sheet to the doctor in attendance. Do not leave the victim unattended. Call a physician immediately. If inhaled : If unconscious, place in recovery position and seek medical advice. If symptoms persist, call a physician. If breathed in, move person into fresh air. In case of skin contact : 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. If symptoms persist, call a physician. In case of eye contact : In the case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Remove contact lenses. Protect unharmed eye. Keep eye wide open while rinsing. If eye irritation persists, consult a specialist. If swallowed : Keep respiratory tract clear. Call a physician immediately. Most important symptoms and effects, both acute and delayed : May cause an allergic skin reaction. Causes eye irritation. Protection of first-aiders : First Aid responders should pay attention to self-protection and use the recommended protective clothing Notes to physician : Treat symptomatically and supportively. SECTION 5. FIRE-FIGHTING MEASURES SAFETY DATA SHEET BENOX B-50 106 WHITE Version 2.1 Revision Date: 08/18/2020 SDS Number: 600000000138 Date of last issue: 04/30/2018 Date of first issue: 04/11/2017 4 / 20 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 : 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. Avoid dust formation. Avoid breathing dust. Remove all sources of ignition. Follow safe handling advice and personal protective equipment recommendations. 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. SAFETY DATA SHEET BENOX B-50 106 WHITE Version 2.1 Revision Date: 08/18/2020 SDS Number: 600000000138 Date of last issue: 04/30/2018 Date of first issue: 04/11/2017 5 / 20 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 : Avoid dust formation. Provide appropriate exhaust ventilation at places where dust is formed. Keep away from heat and sources of ignition. Use only explosion-proof equipment. Keep away from combustible material. Advice on safe handling : Do not breathe vapors/dust. Avoid exposure - obtain special instructions before use. Avoid contact with skin and eyes. Take precautionary measures against static discharges. Never return any product to the container from which it was originally removed. Provide sufficient air exchange and/or exhaust in work rooms. Avoid confinement. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Smoking, eating and drinking should be prohibited in the application area. Wash thoroughly after handling. For personal protection see section 8. Persons susceptible to skin sensitization problems or asthma, allergies, chronic or recurrent respiratory disease should not be employed in any process in which this mixture is being used. Protect from contamination. Conditions for safe storage : Avoid impurities (e.g. rust, dust, ash), risk of decomposition. Electrical installations / working materials must comply with the technological safety standards. Containers which are opened must be carefully resealed and SAFETY DATA SHEET BENOX B-50 106 WHITE Version 2.1 Revision Date: 08/18/2020 SDS Number: 600000000138 Date of last issue: 04/30/2018 Date of first issue: 04/11/2017 6 / 20 kept upright to prevent leakage. Store in original container. Keep containers tightly closed in a cool, well-ventilated place. Store in accordance with the particular national regulations. Materials to avoid : Keep away from strong acids, bases, heavy metal salts and other reducing substances. Recommended storage tem- perature : < 100 F < 38 C Further information on stor- age stability : No decomposition if stored normally. SECTION 8.
