First-aid measures

Most important symptoms and effects
Dust may be irritating to the respiratory tract and cause symptoms of bronchitis.
Description of first aid measures
General
In all cases of doubt, or when symptoms persist, seek medical attention.
Inhalation
Remove to fresh air. If not breathing, give artificial respiration. Oxygen may additionally be given, by trained personned, if it is available. Get medical attention if symptoms occur.
Skin
Flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical attention if irritation develops and persists. Wash clothing before reuse. Thorougly clean or destroy contaminated shoes.
Eye
Immediately flush eyes with plenty of water. If easy to do, contact lenses should be removed during the flushing, by trained personnel. Occasionally hold the eyelids apart during the flushing to ensure rinsing the entire surface of the eye and lids with water. Get medical attention if irritation develops and persists.
Ingestion
Call a physician or poison control center immediately. Induce vomiting only if directed by medical personnel. The patient should lie on their left side while vomiting to reduce the risk of aspiration. Never give anything by mouth to an unconscious or convulsing person.
Indication of any immediate medical attention and special treatment needed
There are no data available that address medical conditions that are generally recognized as being aggravated by exposure to this material.
Attending physician should treat exposed patients symptomatically.

Fire-fighting measures

Extinguishing media
waterspray, foam, sand, dry chemical powder, CO2
Unsuitable extinguishing media
halones
Hazardous decomposition / combustion products
CO2, carbon monoxide
Toluene, 4-methylbenzoic acid
Protective equipment
Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves.
Other information
Evacuate all non-essential personnel. Extinguish a small fire with powder or carbon dioxide then apply water to prevent re-ignition. Cool closed containers with water. Water used to extinguish a fire should not be allowed to enter the drainage system or water courses. After a fire, ventilate thoroughly the area and soak with water, clean the walls and metallic surfaces.
Fire and explosion hazard
CAUTION: reignition may occur. Decomposition under effect of heating (See also Section Hazardous decomposition products). If involved in a fire, it will support combustion. In case of fire and/or explosion do not breathe fumes.

Accidental release measures

Personal precautions
Do not breathe dust. For personal protection see Exposure Controls / Personal Protection.
Environmental precautions
Do not allow to enter drains or water courses.
Methods and material for containment and cleaning up
Stop leakage if possible. Eliminate all sources of ignition, and do not generate flames or sparks. Sweek up and put it into a container for disposal. Avoid dust generation. Keep contents moist. The waste should NOT be confined. FLush surroundings with large amounts of water and soap.
Other information
CAUTION: reignition may occur. Evacuate personnel to safe area.

Handling and storage

Precautions for safe handling
Never weigh out in the storage room. When using do not eat, drink or smoke. Do not breathe dust. Handle in well ventilated areas. Eliminate all sources of ignition, and do not generate flames or sparks. Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g. accelerators, driers, metal soaps). Keep product and emptied container away from heat and sources of ignition. Confinement must be avoided. Avoid incompatible materials (see Stability and Reactivity).
Fire and explosion prevention
Avoid dust generation. Do not cut or weld on or near this container even when empty.
Conditions for safe storage
Store in accordnace with local/national regulations. Keep away from food, drink and animal feedingstuffs. Store in a dry well ventilated place away from sources of heat and direct sunlight. Store separate from other chemicals. Keep only in the original container.
Storage
For maximum quality store below: 25 oC
Other information
It is recommended to use electrical equipment of temperature group T3. However, autoignition can never be excluded. Wash hands thorougly after handling or contact. Keep working clothing separately and do not take them home.

Exposure controls / personal protection

Control parameters
Ensure good ventilation and local exhaustion of the working area. Explosion proof ventilation recommended.
Personal protection
Respiratory
In case of dust formation use dust mask.
Hand
Wear suitable protective gloves of neoprene or synthetic rubber.
Eye
Wear eye/face protection.
Skin and body
Wear suitable protective clothing.
Other information
Emergency-shower and facilities for rinsing eyes must be accessibl. Launder clothes before reuse.

Stability and reactivity

Chemical stability
SADT - (Self accelerating decompostion temperature) is the lowest temperature at which self accelerating decomposition may occur with a substance in the packaging as used in transport.
A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can be caused by thermal decomposition at and above the following temperature: 90 oC. Contact with incompatible substances can cause decomposition at or below the SADT 90 oC.
Conditions to avoid
To maintain quality store in original closed container below: 25 oC.
Confinement must be avoided.
Incompatible materials
Avoid contact with rust, iron and Copper. Contact with incompatible materials such as acids, alkalies, heavy metals and reducing agents will result in hazardous decomposition. Do not mix with peroxide accelerators. Use only Stainless steel 316, PP, polyethylene or glass-lined equipment. Contact Akzo Nobel for more information.
Possibility of hazardous reactions
Polymerization does not occur.
Hazardous decomposition products
Hazardous decomposition products; Toluene, 4-Methylbenzoic acid.
Other information
Emergency procedures will vary depending on conditions. The customer must have an emergency response plan in place. Contact Akzo Nobel for assistance with developing an emergency response plan.

Disposal considerations

Product
Due to the high risk of contamination recycling/recovery is not recommended. Waste disposal in accordnace with regulations (most probably controlled incineration).
Contaminated packaging
According to local regulations. Emptied containers might retain product residues. Follow all warnings even after the container is emptied. Do not wash residues into drains or other waterways.
Other information
For further advice contact manufacturer.
Waste code number
Please refer to your specific industry in the European Waste Catalogue.
