EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Headache. Nausea. Vomiting. Muscular pain. Symptoms may be delayed (see Notes).
    		Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! Redness. Pain (Further see Inhalation).
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES

    		• Face shield, 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
    		• Abdominal pain. Nausea. Vomiting (further see Inhalation).
    		Do not eat, drink, or smoke during work.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). 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: complete protective clothing including self-contained breathing apparatus).
    		Separated from strong oxidants, food and feedstuffs.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS OR PALE YELLOW LIQUID.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating and on burning producing toxic fumes including phosphorous oxides). Reacts with oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 0.1 mg/m3 (skin) (ACGIH 1992-1993).


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

    INHALATION RISK:
     No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20░C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance may cause effects on the central nervous system and peripheral nervous system , resulting in impaired functions (paralysis). Exposure above OEL may result in permanent paralysis. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     The substance may have effects on the nervous system , resulting in impaired functions and muscular paralysis.
