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 In case of contact with the product or the cured product dust or particulate, immediately wash
skin with mild soap and water. Use a washcloth to help remove the fibres. To avoid further
irritation, do not rub or scratch irritated areas. Rubbing or scratching may force fibres into the
skin. Get medical attention immediately if the irritation persists.
Eye contact In case of contact with the product or the cured product dust or particulate, immediately flush
eyes with large amounts of water for at least 15 minutes, keeping the eyelids open. Get
medical attention immediately.
Most important symptoms and effects, both acute and delayed
General information Filaments are mechanical irritants and may induce temporary mouth, nose and throat
irritation. Skin or eye contact may cause itching and temporary irritation. Ingestion may cause
temporary mechanical irritation of the digestive tract. Pre-existing conditions such as
respiratory or skin disorders may be aggravated by exposure to the product or dust/particulate
generated from machining/grinding of the cured product.
5.Fire-fighting measures
Extinguishing media
Suitable extinguishing mediaExtinguish with 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 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
Above 650 C, if incomplete combustion occurs and depending on air supply and temperature,
there may be release of carbon monoxide and dioxide and products of low molecular weight.
Advice for firefighters
Special protective equipment
for firefighters
Wear positive-pressure self-contained breathing apparatus (SCBA) and appropriate protective
clothing.
