TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible.
NO open flames.
Water spray, powder.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding).

EXPOSURE
PREVENT DISPERSION OF DUST!

  • INHALATION
    		• Cough, headache.
    		Ventilation (not if powder).
    		Fresh air, rest, and refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness, pain.
    		Protective gloves, protective clothing.
    		Remove contaminated clothes, rinse skin with plenty of water or shower, and refer for medical attention.
  • EYES
    		• Redness, pain, blurred vision.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Cough, nausea.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth, give nothing to drink, and refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers, wash away remainder with plenty of water (extra personal protection: P2 filter respirator for harmful particles).
    		Separated from strong oxidants, dry, ventilation along the floor.

    PHYSICAL DANGERS:
     Dust explosion possible if in powder or granular form, mixed with air.

    CHEMICAL DANGERS:
     Reacts withstrongoxidants causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS:
     TLV not established.
    PDK not established.


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation and through the skin, andby ingestion.

    INHALATION RISK:
     A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C;on dispersing, however, faster!

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin, and the respiratory tract.
