ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Foam, powder, carbon dioxide.
EXPLOSION The explosion hazard will depend on the solvent used in the formulation or on the characteristics of the dust.


EXPOSURE
STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Convulsions. Dizziness. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramp, excessive salivation.
    Local exhaust or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! (Further see Inhalation).
    Protective gloves. Protective clothing.
    Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES

  • Face shield, or eye protection in combination with breathing protection if powder.
    First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
  • Abdominal cramps. Diarrhoea. Laboured breathing. Nausea. Unconsciousness. Vomiting. Pupillary constriction, muscle cramps, excessive salivation.
    Do not eat, drink, or smoke during work.
    Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Do NOT wash away into sewer. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from food and feedstuffs. Dry.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    YELLOW TO BROWN CRYSTALLINE POWDER , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on heating and on burning producing toxic and corrosive fumes including nitrogen oxides, phosphorous oxides, sulfur oxides. The substance decomposes under influence of alkalies (hydrolysis).

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: ppm; 0.5 mg/m3 (skin) (ACGIH 1991-1992).


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

    INHALATION RISK:
    Evaporation at 20C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly especially if powdered.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance may cause effects on the nervous system , resulting in convulsions, respiratory failure. Cholinesterase inhibitor. Exposure at high level may result in death. The effects may be delayed. Medical observation is indicated.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Cholinesterase inhibitor; cumulative effect is possible: see acute hazards/symptoms.
    PHYSICAL
    PROPERTIES
    Melting point: 36C
    Relative density (water = 1): 1.27 at 25C
    Solubility in water: none
    Vapour pressure, Pa at 25C: < 0.01
    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to bees and fish.
    NOTES
    Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of acute intoxication do not become manifest until 30 minutes to 1-2 hours. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home.
