TYPES OF
HAZARD/
EXPOSURE
ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Combustible under specific conditions. Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.


EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Muscle twitching. Pupillary constriction, muscle cramp, excessive salivation. Dizziness. Laboured breathing. Sweating. Unconsciousness. Symptoms may be delayed (see Notes).
    Ventilation (not if powder), local exhaust, or breathing protection.
    Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! (Further see Inhalation).
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
  • EYES
  • Aerosols will be aborbed (further see Inhalation).
    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
  • Headache. Nausea. Vomiting. Abdominal cramps. Diarrhoea. Convulsions (further see Inhalation).
    Do not eat, drink, or smoke during work. Wash hands before eating.
    Rinse mouth. Give a slurry of activated charcoal in water to drink. 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 sealable 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).
    Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Dry. Well closed. Keep in a well-ventilated room.
    Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS HYGROSCOPIC CRYSTALS.




    CHEMICAL DANGERS:
    The substance decomposes on heating or on burning producing toxic and irritating fumes including nitrogen oxides, phosphorous oxides. Attacks iron, steel, brass.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 0.25 ppm; mg/m3 (skin) (ACGIH 1994-1995).


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

    INHALATION RISK:
    Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, 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 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
    Boiling point at 0.00007 kPa: 125C
    Melting point: 54-55C
    Relative density (water = 1): 1.3
    Solubility in water, g/100 ml at 20C: 100g/100ml (good)
    Vapour pressure, Pa at 20C: 0.0003
    ENVIRONMENTAL
    DATA
    The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment; special attention should be given to honey bees, birds, mammals. The substance may cause long-term effects in the aquatic environment. Avoid release to the environment in circumstances different to normal use.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s). Carrier solvents used in commercial formulations may change physical and toxicological properties. Do NOT take working clothes home. Azodrin, Bilobran, Crisodrin, Monocron, Nuvacron, Plantdrin, Susvin are trade names.
