First-aid measures
Description of necessary first-aid measures, Most important symptoms/effects, acute and delayed:
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 immediately, abundantly and thoroughly with water.
Eye contact:
Wash immediately, abundantly and thoroughly with water. If irritation persists, consult an ophthalmologist.

Accidental release measures
Personal precautions, protective equipment and emergency procedures:
Prohibit all sources of sparks and ignition - Do not smoke. Avoid contact with skin and eyes and inhalation of vapours. Use personal
protective equipment.
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. Shovel or sweep up. Shovel into suitable
container for disposal. After cleaning, flush away traces with water. Dilute with water. Recover waste water for processing later.
Handling and storage
Precautions for safe handling:
Technical measures/Precautions:
Storage and handling precautions applicable to products: Liquid. Flammable (when hot). With vapours explosive in air. Provide appropriate
exhaust ventilation at machinery. Provide showers, eye-baths.
Safe handling advice:
Keep well away from naked flames. Prohibit all sources of sparks and ignition - Do not smoke. Only use safety equipment. Avoid prolonged
contact with eyes, skin and clothing.
Hygiene measures:
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 tightly closed in a dry, cool and well-ventilated place. Store away from heat and ignition sources. Store in insulated containers. Keep
under nitrogen. Provide a catch-tank in a bunded area. Provide electrical earthing of equipment and electrical equipment usable in explosive
atmospheres.
Storage temperature: > 20 °C (to prevent crystallization).
