Guidance on Safe Use

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. If skin irritation persists, call a physician.

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:

If entering a saturated atmosphere, wear a self contained breathing apparatus.

Fire-fighting measures

Extinguishing media

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

Advice for firefighters:

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. Use personal protective equipment. In case of leak, wear a self-contained breathing apparatus. Prohibit contact with skin and eyes and inhalation of vapours.

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:

Recovery:

Pump into a labelled inert emergency tank. Absorb the remainder with an inert absorbent material. Rinse with water. Recover waste water for processing later.

Elimination:

Destroy product by oxidation with dilute solutions of : Hydrogen peroxide or 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. Sensitizing. Highly flammable With vapours explosive in air. Dangerous for the environment. Provide appropriate exhaust ventilation at machinery. Provide showers, eye-baths. Provide water supplies near the point of use. 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. Only use safety equipment.

Hygiene measures:

Prohibit contact with skin and eyes and inhalation of vapours. Remove and wash contaminated clothing before re-use. When using do not eat, drink or smoke.

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 impermeable floor. Provide electrical earthing of equipment and electrical equipment usable in explosive atmospheres.
