FIRE FIGHTING
FIRE Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT!

  • INHALATION
    		• Cough. Sore throat.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest.
  • SKIN

    		• Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES

    		• Safety spectacles, or eye protection in combination with breathing protection.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION


    		• Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
