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


EXPOSURE
PREVENT GENERATION OF MISTS! STRICT HYGIENE! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Pupillary constriction, muscle cramp, excessive salivation. Sweating. Nausea. Dizziness. Laboured breathing. Convulsions. Unconsciousness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! (see Inhalation).
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES

    		• 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
    		• Vomiting. Abdominal cramps. Diarrhoea. (further see Inhalation).
    		Do not eat, drink, or smoke during work. Wash hands before eating.
    		Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from food and feedstuffs. Well closed.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS LIQUID.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating or on burning producing toxic and corrosive fumes including phosphorous oxides and sulfur oxides.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: ppm; 0.4 mg/m3 (as TWA) (skin) (ACGIH 1997).
    MAK not established.
    OSHA PEL: none
    NIOSH REL: 0.4 mg/m3 skin
    NIOSH IDLH: No data


    		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 on spraying.

    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 unconsciousness and 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: -12/-13°C
    Relative density (water = 1): 1.2
    Solubility in water, g/100 ml at 20°C: 0.0001
    		 Vapour pressure, Pa at 25°C: 0.0002
    Octanol/water partition coefficient as log Pow: 5.073
    ENVIRONMENTAL
    DATA
         		The substance is very toxic to aquatic organisms. 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. Nialate, Niagara 1240, Rhodocide and Vegfru fosmite are trade names.
