First-aid measures

As a general rule, in case of doubt or if symptoms persist, always call a doctor. NEVER induce swallowing by an unconscious person.
1. Description of first aid measures
In the event of exposure by inhalation :
In the event of massive inhalation of dust, remove the person exposed to fresh air. Keep warm and at rest.
If the person is unconscious, place in recovery position.
Notify a doctor in all events, to ascertain whether observation and supportive hospital care will be necessary.
If breathing is irregular or has stopped, effect mouth-to-mouth resuscitation and call a doctor.
In the event of splashes or contact with eyes :
Wash thoroughly with soft, clean water for 15 minutes holding the eyelids open.
Regardless of the initial state, refer the patient to an ophthalmologist and show him the label.
If there is any redness, pain or visual impairment, consult an ophthalmologist.
In the event of splashes or contact with skin :
Remove contaminated clothing and wash the skin thoroughly with soap and water or a recognised cleaner.
Watch out for any remaining product between skin and clothing, watches, shoes, etc.
If the contaminated area is widespread and/or there is damage to the skin, a doctor must be consulted or the patient transferred to hospital.
In the event of swallowing :
Do not give the patient anything orally.
In the event of swallowing, if the quantity is small (no more than one mouthful), rinse the mouth with water and consult a doctor. Seek medical attention immediately, showing the label.

Fire-fighting measures

1. Extinguishing media
Suitable methods of extinction
In the event of a fire, use :
All means of extinstion can be used.
Unsuitable methods of extincion In the event of a fire, do not use : Strong water jet
2. Special hazards arising from the substance or mixture
A fire will often produce a thick black smoke. Exposure to decomposition products may be hazardous to health. Do not breathe in smoke.
In the event of a fire, the following may be formed :
- carbon monoxide (CO)
- carbon dioxide (CO2)
- nitrogen oxide (NO)
- nitrogen dioxide (NO2)
3. Advice for firefighters
Due to the toxicity of the gas emitted on thermal decomposition of the products, fire-fighting personnel are to be equipped with autonomous insulating breathing apparatus.

Accidental release measures

1. Personal precautions, protective equipment and emergency procedures
Consult the safety measures listed under sections "handling and storage" and " Exposure controls/ Personal Protection "
For non first aid worker
Avoid any contact with the skin and eyes. Avoid inhaling dust.
If a large quantity has been spilt, evacuate all personnel and only allow intervention by trained operators equipped with safety apparatus.
For first aid worker
First aid workers will be equipped with suitable personal protective equipment (See section Exposure controls / Personal Protection).
6.2. Environmental precautions
Prevent any material from entering drains or waterways.
6.3. Methods and material for containment and cleaning up
Retrieve the product by mechanical means (sweeping/vacuuming) : do not generate dust.

Handling and storage

Requirements relating to storage premises apply to all facilities where the substance is handled.
.1. Precautions for safe handling
Always wash hands after handling.
Remove and wash contaminated clothing before re-using.
Provide emergency showers and eye wash stations will be required in facilities where the substance is handled constantly.
Fire prevention :
Handle in well-ventilated areas.
Prevent access by unauthorised personnel.
Recommended equipment and procedures :
For personal protection, see section "Exposure controls / Personal protection".
Observe precautions stated on label and also industrial safety regulations. Avoid inhaling dust.
Also provide breathing apparatus for certain short tasks of an exceptional nature and for emergency interventions.
In all cases, recover emissions at source.
Avoid eye contact with this substance at all times.
Prohibited equipment and procedures :
No smoking, eating or drinking in areas where the substance is used.
.2. Conditions for safe storage, including any incompatibilities
Keep only in the original container at a temperature not exceeding: - 20 ° C
Keep the container tightly closed in a dry, well-ventilated place.
Always keep in packaging made of an identical material to the original

Exposure controls / personal protection

. Exposure controls
Personal protection measures, such as personal protective equipment
Pictogram(s) indicating the obligation of wearing personal protective equipment (PPE) :
protective glases, protective clothes, protective gloves, mask

Use personal protective equipment that is clean and has been properly maintained.
Store personal protective equipment in a clean place, away from the work area.
Never eat, drink or smoke during use. Remove and wash contaminated clothing before re-using. Ensure that there is adequate ventilation,
especially in confined areas.
- Eye / face protection
Avoid contact with eyes.
Before handling powders or dust emission, wear mask goggles in accordance with standard EN166.
Prescription glasses are not considered as protection.
Provide eyewash stations in facilities where the product is handled constantly.
- Hand protection
Wear suitable protective gloves in the event of prolonged or repeated skin contact.
Use suitable protective gloves that are resistant to chemical agents in accordance with standard EN374.
Gloves must be selected according to the application and duration of use at the workstation.
Protective gloves need to be selected according to their suitability for the workstation in question :
other chemical products that may be handled, necessary physical protections (cutting, pricking, heat protection), level of dexterity required.
- Body protection
Avoid skin contact.
Wear suitable protective clothing.
Work clothing worn by personnel shall be laundered regularly.
After contact with the product, all parts of the body that have been soiled must be washed.
- Respiratory protection
Avoid breathing dust.
If the ventilation is insufficient, wear appropriate breathing apparatus.
When workers are confronted with concentrations that are above occupational exposure limits,
they must wear a suitable, approved, respiratory protection device.

Stability and reactivity

1. Reactivity
Humidity sensitive product (hydrolysis with carbon dioxide and formation of free acid) and heat (decarboxylation and polymerization).
In general, the NCA derivatives readily polymerize with evolution of carbon dioxide and therefore packaging overpressure.
This polymerization is exothermic and may turn violent if it is catalyzed by a base or an acid
In the absence of catalyst, the temperature (maintained at temperature higher than that advocated below or gradual elevation) causes a slow
to moderate polymerization.
Tests have shown that this substance CAS is stable at a temperature of - 20 ° C. It must be observed for storage except for short periods.
2. Chemical stability
This substance is stable under the recommended handling and storage conditions in section "handling and storage".
3. Possibility of hazardous reactions
No data available.
4. Conditions to avoid
Avoid :
- formation of dusts
Dusts can form an explosive mixture with air. Temperatures above : - 20 °C
5. Incompatible materials
Keep away from :
- water
- amines
- alcohols
- strong acids
- strong oxidising agents
6. Hazardous decomposition products
The thermal decomposition may release/form :
- carbon monoxide (CO)
- carbon dioxide (CO2)
- nitrogen oxide (NO)
- nitrogen dioxide (NO2)
Formation of Carbon Dioxide by simply raising the temperature.
