reaction products of acetic anhydride and adipic acid

Guidance on Safe Use

First-aid measures

General information:

Immediately remove any clothing soiled by the product. Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident. Take affected persons out into the fresh air. Personal protection for the First Aider.

After inhalation:

Supply fresh air or oxygen; call for doctor. In case of unconsciousness place patient stably in side position for transportation. Supply fresh air. If required, provide artificial respiration. Keep patient warm. Consult doctor if symptoms persist. Use a respiration bag or breathing device. Corrosive substances may cause lung damage. As this reaction may be delayed up to 24 hours after exposure, affected individuals need complete rest (preferably in semi recumbent posture.), and must be kept under medical observation even if no symptoms are (yet) manifested. Inhalation of vapours and aerosols (mists, fumes) may cause lung oedema.

After skin contact:

Quickly remove all contaminated clothing, including footwear. Immediately flush body and clothes with large amounts of water, using safety shower if available. Immediate medical treatment necessary. Failure to treat burns can prevent wounds from healing.

After eye contact:

Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Rinse opened eye for at least 15 minutes under running water. Seek immediate medical advice.

After swallowing:

Rinse out mouth and then drink plenty of water. Do not induce vomiting; call for medical help immediately. Seek immediate medical advice.

Handling and storage

Precautions for safe handling

Keep receptacles tightly sealed. Ensure good ventilation/exhaustion at the workplace. Prevent formation of aerosols. Do not eat, drink or smoke when using this product. In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.

Information about protection against explosions and fires:

Protect from heat. Fumes can combine with air to form an explosive mixture. The product forms flammable fumes when heated.

Exposure controls / personal protection

Personal protective equipment:

General protective and hygienic measures

Keep away from foodstuffs, beverages and feed. Immediately remove all soiled and contaminated clothing. Store protective clothing separately.

Do not inhale gases / fumes / aerosols. Avoid contact with the eyes and skin. Do not eat, drink, smoke or sniff while working. Be sure to clean skin thoroughly after work and before breaks. Do not carry product impregnated cleaning cloths in pockets.

Breathing equipment:

Ensure good ventilation/exhaustion at the workplace. Respiratory protection when aerosol or mist are formed in the breathing zone. In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.

Recommended filter device for short term use: Filter ABEK

Protection of hands:

Use chemical resistant gloves classified under standard EN 374: Protective gloves against chemicals and micro-organisms. The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer. Check the permeability prior to each anewed use of the glove. For the permanent contact in work areas with heightened risk of injury (mechanical hazard) no recommendation for a suitable glove material can be given. Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation

Penetration time of glove material

When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes according to EN 374) is recommended. When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according to EN 374) is recommended.

NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all requisite workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), as well as the instructions/specifications provided by the glove supplier. The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed. Therefore a maximum wearing time, which corresponds to 50% of the penetration time, is recommended.

For the permanent contact gloves made of the following materials are suitable: Butyl rubber (BR), Chloroprene rubber (CR). Recommended thickness of the material: ≥ 0.7 mm.

For the permanent contact of a maximum of 15 minutes gloves made of the following materials are suitable: Butyl rubber (BR), Fluorocarbon rubber (Viton), Natural rubber (NR), Chloroprene rubber (CR), PVC gloves. Recommended thickness of the material: ≥ 0.5 mm.

As protection from splashes gloves made of the following materials are suitable: Butyl rubber (BR), Fluorocarbon rubber (Viton), Natural rubber (NR), Chloroprene rubber (CR), PVC gloves. Recommended thickness of the material: ≥ 0.2 mm.

Not suitable are gloves made of the following materials: Nitrile rubber (NBR), Leather gloves, Strong gloves, PVA gloves.

Eye protection:

Safety glasses. Full face shields may be required for supplementary but never for primary protection of eyes.

Body protection: Acid resistant protective clothing

Boots: made out of rubber, made out of plastic
