TYPES OF
HAZARD/
EXPOSURE 		ACUTE HAZARDS/
SYMPTOMS 		PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Liquid formulations containing organic solvents may be flammable. Gives off irritating or toxic fumes (or gases) in a fire.

Powder, water spray, foam, carbon dioxide.
EXPLOSION Risk of fire and explosion if formulations contain flammable/explosive solvents.


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

  • INHALATION
    		• Cough. Laboured breathing. Vomiting. Weakness.
    		Ventilation (not if powder).
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain. Blurred vision.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• (further see Inhalation).
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Rinse mouth. 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: P2 filter respirator for harmful particles).
    		Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs. Ventilation along the floor.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS CRYSTALS.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride (see ICSC # 0163).

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    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; on spraying or dispersing, however, much faster.

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

    ENVIRONMENTAL
    DATA
    N O T E S
    If the pesticide is present under the form of a formulation containing hydrocarbon solvents, vomiting may not be induced. Carrier solvents used in commercial formulations may change physical and toxicological properties. Banvel, Banex, Dianat, Fallowmaster, Mediben, Metambane, Tracker, Trooper and Velsicol are trade names. If the pesticide is formulated with an organic solvent, also consult ICSC of the solvent used.
