First-aid measures

4.1 Description of first aid measures:
In all cases of doubt, or when symptoms persist, seek medical attention.
4.1.1 In case of inhalation:
Remove to fresh air. If not breathing, give artificial respiration. Oxygen may additionally be given, by trained personnel, if it is available. Get medical attention if symptoms occur.
4.1.2 In case of skin contact:
Remove contaminated clothing and wash affected area thoroughly with soap and water. Report for medical attention.
4.1.3 In case of eyes contact:
Irrigate eyes with eyewash solution or clean water, holding the eyelids apart, for at least fifteen minutes (do not let run-off water contaminate unaffected eye). Obtain immediate medical aid.
4.1.4 In case of ingestion:
Do not induce vomiting. Rinse out patient’s mouth (if conscious) with water then give plenty of water to drink; keep warm and at rest. If unconscious, place/transport patient in secured side recovery position. Obtain immediate medical aid.
4.2 Most important symptoms and effects, both acute and delayed:
Inhaled dust is harmful and may cause irritation of the respiratory system (eg coughing and sneezing). May cause irritation (eg redness, tears, conjunctivitis). Harmful by skin absorption and may cause irritation (eg reddening of skin, itching). Harmful if swallowed and may cause gastric disturbance (eg vomiting, diarrhoea, stomach cramps).
4.3 Indication of any immediate medical attention and special treatment needed:
If skin irritation or rash occurs, get medical advice/attention.

Fire-fighting measures

5.1 Extinguishing media:
Suitable extinguishing media:
Substance is combustible. If involved in a fire extinguish with water spray. Foam, dry powder or CO2 may also be used.
Unsuitable extinguishing media:
Not available.
5.2 Special hazards arising from the
substance or mixture
May produce irritating and/or toxic fumes of organic compounds and carbon monoxide. Mixtures of fine dust with air may be explosive.
5.3 Advice for firefighters:
Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves.

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures:
6.1.1 For non-emergency personnel:
Prevent build up of dust by ensuring adequate ventilation. Keep all sources of ignition away. Keep people and animals away. If the accidental release is significant, consider evacuating workplace or exposed area. Wear protective clothing as specified in Section 8.
6.1.2 For emergency responders:
Wear an appropriate NIOSH/MSHA approved respirator if dust is generated.
6.2 Environmental Precautions:
Prevent spilt material or contaminated wash or fire-fighting water entering drains or watercourses – contain by portable bunding if necessary and protect drains with covers. Dampen spillages with water to prevent dust dispersion. Collect up spillages without delay.
6.3 Methods for Containment and Cleaning up:
Collect up powder using spark proof industrial vacuum cleaner with high efficiency filters. Otherwise, collect up using non-metal shovel avoiding formation of dust cloud (dampen solid if necessary if it not to be reused).Transfer collected material to steel or plastic drum for safe disposal – see Section 13. Subsequently wash down affected area with detergent and water. Prevent chemical or contaminated wash water from entering drains or watercourses.

Handling and storage

7.1 Precautions for safe handling:
7.1.1 Protective measures:
Generally handle material in ways which minimise dust build up; where dust formation is likely ensure adequate filtered ventilation and keep all ignition sources away. In a materials handling context (eg process facility) ensure adequate provision for dust explosion relief on any equipment handling the material in a dry or powdered state. Take precautions against static discharge such as grounding and low vertical drops; tip from plastic bags onto open stainless steel chutes and not into contained/enclosed spaces. Avoid spillages especially in the presence of oxidising agents, drains and watercourses. Avoid damaging packages. See Section 8 for occupational hygiene and exposure prevention measures.
7.1.2 Advice on general occupational
Do not eat, drink and smoke in work areas. Wash hands after use. Remove contaminated clothing and protective equipment before entering eating areas.
7.2 Conditions for safe storage, including
any incompatibilities:
Material is a relatively stable organic solid which might form a flammable dust. Store in a designated, well ventilated, dry room or other suitable area away from direct sunlight (discolours).
7.3 Specific end use(s):
Not applicable.

Exposure controls / personal protection

8.2 Exposure controls:
8.2.1Appropriate engineering controls:
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.
8.2.2 Individual protection measures, such as personal protective equipment:
Eye/face protection:
Wear safety glasses with side pieces or safety goggles to EN166 or 29 CFR 1910.133.
Hand protection:
Wear chemical resistant protective gloves (eg rubber, neoprene, butyl, PVC or nitrile) to EN374. Do not wear heavily contaminated or damaged gloves, and decontaminate before removal. Check condition regularly, especially for abrasion damage.
Body protection:
Wear standard workplace protective clothing (eg laboratory coat, washable or disposable overalls, protective footwear).
Respiratory protection:
Depending upon workplace/incident circumstances use filtering respirator with filter cartridge Type P3 (Particulates) or breathing apparatus – see note below for types available. In an emergency or where the concentration of dust is unknown but could be high use clean air supplied breathing apparatus. Do not use a filtering respirator in: atmospheres containing <19.5% oxygen; poorly ventilated areas; confined spaces; when concentration of dust is unknown, is ‘immediately dangerous to life or health’ or is above any workplace exposure limit; for fire-fighting.
Thermal hazards:
Wear suitable protective clothing to prevent heat.
8.2.3 Environmental exposure controls:
Avoid discharge into the environment.
According to local regulations, Federal and official regulations.

Stability and reactivity

10.1 Reactivity:
The substance is stable under normal storage and handling conditions.
10.2 Chemical stability:
Stable at room temperature in closed containers under normal storage and handling conditions. Although like most organic substances is combustible and will decompose if heated. Darkens on exposure to light or air.
10.3 Possibility of hazardous reactions:
Not reported to undergo hazardous reactions although like most organic substances may react and ignite with oxidising agents. Although like many substances may initiate polymerisation or catalyse decomposition of certain organic liquids (eg monomers) if allowed to contaminate them.
10.4 Conditions to avoid:
Incompatible materials. Heat, damp, and exposure to light or air.
10.5 Incompatible materials:
Strong oxidizing agents. Acid chlorides, acid anhydrides, bases, oxidizing agents, metals, alkalis.
10.6 Hazardous decomposition products:
May produce irritating and/or toxic fumes of organic compounds and carbon monoxide. Mixtures of fine dust with air may be explosive.

Disposal considerations

13.1 Waste treatment methods:
Due to the high risk of contamination recycling/recovery is not recommended. Waste disposal in accordance with regulations (most probably controlled incineration).
