EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
    		• Cough. Headache. Nausea. Sore throat. Unconsciousness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness. Burning sensation.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety goggles, or face shield.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: A/P2 filter respirator for organic vapour and harmful dust).
    		Ventilation along the floor.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS, ODOURLESS VISCOUS LIQUID.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides. Reacts with warm water producing corrosive phosphoric acid and butanol. Attacks some forms of plastics, rubber and coatings.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.2 ppm; 2.2 mg/m3 (as TWA) (ACGIH 1997).


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation of its vapour.

    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.

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

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     See Notes.
