First-aid measures

General advice: Take off immediately all contaminated clothing.

Inhalation: Move to fresh air. Oxygen or artificial respiration if needed. In case of persistent problems : Consult a physician.

Skin contact: Wash off immediately with soap and plenty of water.

Eye contact: Wash immediately, abundantly and thoroughly with water. If irritation persists, consult an ophthalmologist.
Ingestion: In case of problems : Consult a doctor.

Protection of first-aiders: In case of insufficient ventilation, wear suitable respiratory equipment.

Fire-fighting measures

Suitable extinguishing media: Foam, Dry powder, Carbon dioxide (CO2)

Special hazards arising from the substance or mixture:
Flammable liquid. Vapours may form explosive mixture with air. Possible re-ignition of vapours from a distance,
Hazards of overpressurization in containers exposed to heat : explosion risk..
Thermal decomposition giving flammable and toxic products : Hydrogen sulphide, Sulphur oxides, Carbon oxides

Precautions for fire-fighters:
Specific methods: Cool containers / tanks with water spray.
Special protective actions for fire-fighters: Wear self-contained breathing apparatus and protective suit.

Accidental release measures

Personal precautions, protective equipment and emergency procedures:
Evacuate non-essential staff and those not equipped with individual protection apparatus. Prohibit all sources of sparks and ignition - Do not smoke. Avoid contact with skin and eyes and inhalation of vapours. Use personal protective equipment. In case of leak, wear a self-contained breathing apparatus.

Environmental precautions:
Do not release into the environment. Do not let product enter drains. Dam up with sand or inert earth (do not use combustible materials).

Methods and materials for containment and cleaning up:
T
Recovery: Pump into a labelled inert emergency tank. Absorb the remainder with an inert absorbent material. Rinse with water and recover for later processing

Elimination:
Destroy product by oxidation with dilute solutions of Hydrogen peroxide, sodium hypochlorite or Destroy the product by incineration (in accordance with local and national regulations).

Handling and storage

Precautions for safe handling:
Technical measures/Precautions:
Storage and handling precautions applicable to products: Liquid. Highly flammable with vapours explosive in air. Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide self-contained breathing apparatus nearby. Well ventilate empty vats and tanks before entering.

Safe handling advice:
Keep well away from naked flames. Take precautionary measures against static discharges. Prohibit all sources of sparks and ignition - Do not smoke.Use product only in closed system. Do not use air for transfers. Open drum carefully as content may be under pressure.

Hygiene measures:
Avoid contact with the skin and the eyes. Avoid inhalation of vapours. Remove and wash contaminated clothing before re-use. Wash hands after handling. Remove contaminated clothing and protective equipment before entering eating areas.

Conditions for safe storage, including any incompatibilities:
Keep containers tightly closed in a cool, well-ventilated place. Store away from heat and ignition sources. Provide a catch-tank in a bunded area. Provide electrical earthing of equipment and electrical equipment usable in explosive atmospheres.

Incompatible products: Strong oxidizing agents

Packaging material:
Recommended: Ordinary steel, Stainless steel, Joints : polyethylene, Rilsan ®, polytetrafluoroethylene (PTFE)
To be avoided: Rubber, Plastic materials
