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.
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
3/10
Revision date: 9/20/2018 Revision: 1.0
HexPly M77HFS (White)
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. 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.
Methods and material for containment and cleaning up
Methods for cleaning up Collect and place in suitable waste disposal containers and seal securely. For waste disposal,
see Section 13.
Reference to other sectionsFor personal protection, see Section 8. For waste disposal, see Section 13.
7. Handling and storage
Precautions for safe handling
Usage precautions Wash at the end of each work shift and before eating, smoking and using the toilet. Promptly
remove any clothing that becomes contaminated. When using, do not eat, drink or smoke.
Carbon fibers contained in some products are electrically conductive and if released during
combustion may present a hazard to unprotected electrical apparatus.
