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
AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!

  • INHALATION

    		• Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN

    		• Protective gloves.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		Safety goggles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION

    		• Do not eat, drink, or smoke during work. Wash hands before eating.
    		Give plenty of water to drink. 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: chemical protection suit including self-contained breathing apparatus).
    		Provision to contain effluent from fire extinguishing. Separated from food and feedstuffs.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS TO WHITE CRYSTALLINE POWDER.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning producing toxic fumes including sulfur oxides, nitrogen oxides.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    INHALATION RISK:
     Evaporation at 20°C 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 irritates the eyes.


    PHYSICAL
    PROPERTIES
    Decomposes below boiling point at 200°C
    Melting point: 137-139°C
    Solubility in water: none
    		Vapour pressure, Pa at 20°C: < 0.001
    Octanol/water partition coefficient as log Pow: -0.46
    ENVIRONMENTAL
    DATA
         		Avoid release to the environment in circumstances different to normal use.
    N O T E S
    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. Adagio, Basagran, Pledge are trade names.
