Composition comments The exact percentage (concentration) of composition has been withheld as a trade secret in accordance with 29 CFR 1910.1200. 4. First-aid measures Description of first aid measures Inhalation With any sign of respiratory distress, affected persons should be taken into fresh air, and made to rest while medical attention is sought. 2/9 Revision date: 12/5/2017 Revision: 0 HexPly M77HF Ingestion Immediately rinse the mouth repeatedly with water, if swallowing has occurred, do not induce vomiting. If requested, give affected person sips of water. Seek medical attention immediately. If vomiting does occur do not allow the affected person to inhale their vomit. Do not give anything by mouth to an unconscious person. Skin Contact With uncured material, immediately wash the affected area with warm, soapy water then clean the skin with resin removing cream, followed by further washing with warm soapy water. Do not use solvents. If irritation persists, seek medical attention. Eye contact Flush with water for at least 15 minutes and seek medical attention if irritation persists. Most important symptoms and effects, both acute and delayed Inhalation Inhalation of dust during cutting, grinding or sanding operations involving this product may cause irritation of the respiratory tract. Skin contact Contact with dust may cause mechanical irritation. Indication of immediate medical attention and special treatment needed Notes for the doctor No specific recommendations. If in doubt, get medical attention promptly. 5. Fire-fighting measures Extinguishing media Suitable extinguishing mediaExtinguish with alcohol-resistant foam, carbon dioxide, dry powder or water fog. Unsuitable extinguishing media Do not use water jet as an extinguisher, as this will spread the fire. Special hazards arising from the substance or mixture Specific hazards Warning! Dust generated from machining, grinding or sanding the cured product may be combustible and could result in fire and/or explosion should the necessary dust concentration in air and ignition source be present. Refer to section 10 for further details. Carbon fibers contained in some products are electrically conductive and if released during combustion may present a hazard to unprotected electrical apparatus. Hazardous combustion products The products of combustion and decomposition depend on other materials present in the fire and the actual conditions of the fire. Burning will release carbon dioxide, water, carbon monoxide and compounds of nitrogen. Advice for firefighters Special protective equipment for firefighters Avoid exposure through use of a self-contained, positive-pressure breathing apparatus. 6. Accidental release measures Personal precautions, protective equipment and emergency procedures Personal precautions Wear suitable protective equipment, including gloves, goggles/face shield, respirator, boots, clothing or apron, as appropriate. Environmental precautions Environmental precautionsDue to the physical nature of this product, environmental release to drains and water courses is not possible.
