EXPOSURE
PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

  • INHALATION
  • Cough (see Ingestion).
    Local exhaust or breathing protection.
    Fresh air, rest.
  • SKIN
  • MAY BE ABSORBED!
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
  • Redness.
    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
  • Excessive salivation. Sweating. Visual disturbance. Diarrhoea. Dizziness. Headache. Laboured breathing. Nausea.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place (extra personal protection: P2 filter respirator for harmful particles).
    Dry. Keep in a well-ventilated room. In glass, high-density plastic, rubber or epoxy resin-protected metal containers.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS TO WHITE EXTREMELY HYGROSCOPIC CRYSTALS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating or on burning producing toxic and corrosive fumes (nitrogen oxides, hydrogen chloride). The substance decomposes on heating with strong aqueous alkali solutions producing trimethylamine and other gaseous products. Attacks many metals in presence of water.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.
    PDK: 0.3 mg/m3 P(USSR 1991).


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

    INHALATION RISK:
    Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly by dispersion.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The aerosol of this substance irritates slightly the eyes and the respiratory tract. The substance may cause effects on the nervous system: cholinergic symptoms without acetylcholinesterase inhibition (see notes).

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    (see Notes).
    PHYSICAL
    PROPERTIES
    Melting point (decomposes): 245°C
    Solubility in water: good (74 g/100 ml at 20°C)
    Vapour pressure, Pa at 20°C: <0.00001
    ENVIRONMENTAL
    DATA

    NOTES
    The technical compound (97-98%) is a yellowish solid. Use of atropine as specific treatment is contraindicated. Data are insufficiently available on the effect of this substance on human health, therefore utmost care must be taken. Carrier solvents used in commercial formulations may change physical and toxicological properties. Cycocel, CCC, Cycogan, Increcel, Retacel, Stabilan are trade names.
