3. Composition / Information on Ingredients

4. First Aid Measures

Ingestion

Ensure breathing passages are not obstructed. The product w ill polymerise rapidly and bond to the mouth making it almost impossible to swallow. Saliva will separate any solidified product in several hours. Prevent the patient from swallowing any separated mass.

Inhalation

Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. If symptoms develop and persist, get medical attention.

Skin Contact

Do not pull bonded skin apart. Soak in w arm soapy water. Gently peel apart using a blunt instrument. If skin is burned due to the rapid generation of heat by a large drop, seek medical attention. If lips are bonded, apply warm water to the lips and encourage wetting and pressure from saliva in mouth. Peel or roll lips apart. Do not pull lips apart with direct opposing force.

Eye Contact

Immediately flush with plenty of water for at least 15 minutes. Get medical attention. If eyelids are bonded closed, release eyelashes with warm water by covering with a wet pad. Do not force eye open. Cyanoacrylate will bond to eye protein and will cause a lachrymatory effect which will help to debond the adhesive. Keep eye covered until debonding is complete, usually within 1-3 days. Medical attention should be sought in case solid particles of polymerised cyanoacrylate trapped behind the eyelid caused abrasive damage

Other Information

Surgery is not necessary to separate accidentally bonded tissues. Experience has show n that bonded tissues are best treated by passive, non-surgical first aid. If rapid curing has caused thermal bums they should be treated symptomatically after adhesive is removed.

Environmental precautions

Ventilate area. Do not allow product to enter sewer or waterways.

Methods and materials for containment and clean up

Do not use cloths for mopping up. Flood with water to complete polymerization and scrape off the floor. Cured material can be disposed of as non-hazardous waste. Refer to Section 8 "Exposure Controls / Personal Protection" prior to clean up.

7. Handling and Storage

Precautions for safe handling

Avoid contact with eyes, skin and clothing. Avoid breathing vapours or mists of this product. Wash thoroughly after handling. Avoid contact with fabric or paper goods. Contact with these materials may cause rapid polymerization which can generate smoke and strong irritating vapours, and cause thermal burns

Conditions for safe storage

For safe storage, store between 2 °C (35.6 °F) and 8 °C (46.4 °F)

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

Use positive down-draft exhaust ventilation if general ventilation is insufficient to maintain vapour concentration below established exposure limits.

Personal protective equipment

Eye and face protection

Safety goggles or safety glasses with side shields. Full face protection should be used if the potential for splashing or spraying of product exists.

Skin protection

Use nitrile gloves and aprons as necessary to prevent contact. Do not use PVC, nylon or cotton.

Body protection

No further data available

Respiratory protection

Use NIOSH approved respirator if there is potential to exceed exposure limit(s)

11. Toxicological Information

Acute effects

Skin, Inhalation, Eyes

Eye contact

Irritating to eyes. Causes excessive tearing. Eyelids may bond.

Skin contact

• Bonds skin in seconds. May cause skin irritation. Cyanoacrylates have been reported to cause allergic reaction but due to rapid polymerization at the skin surface, an allergic response is rare.
• Cyanoacrylates generate heat on solidification. In rare circumstances a large drop will burn the skin. Cured adhesive does not present a health hazard even if bonded to the skin.

Ingestion

Not expected to be harmful by ingestion. Rapidly polymerises (solidifies) and bonds in mouth. It is almost impossible to swallow.

Inhalation

Exposure to vapours above the established exposure limit results in respiratory irritation, which may lead to difficulty in breathing and tightness in the chest

Toxicity and irritation
