EXPOSURE
STRICT HYGIENE!

  • INHALATION
    		• Blue lips or finger nails. Dizziness. Headache. Nausea. Vomiting. Weakness.
    		Local exhaust or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• MAY BE ABSORBED! (See Inhalation).
    		Protective gloves. Protective clothing.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES

    		• Safety goggles, 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
    		• (see Inhalation).

    		Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!).
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Do NOT absorb in saw-dust or other combustible absorbents. Do NOT let this chemical enter the environment. (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Separated from combustible and reducing substances, food and feedstuffs. Keep in a well-ventilated room.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     YELLOWISH CRYSTALS , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic gases (nitrogen oxides, hydrogen chloride, phosgene and chlorine). The substance is a strong oxidant and reacts violently with combustible and reducing materials.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.1 ppm; 0.64 mg/m3 (as TWA) A3 (skin) (ACGIH 1997).
    OSHA PEL: TWA 1 mg/m3 skin
    NIOSH REL: Ca See Appendix A skin
    NIOSH IDLH: Potential occupational carcinogen 100 mg/m3


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

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance may cause effects on the blood , resulting in formation of methaemoglobin. See Notes.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization.
    PHYSICAL
    PROPERTIES
    Boiling point: 242°C
    Melting point: 82-84°C
    Relative density (water = 1): 1.3
    Solubility in water: none
    		 Vapour pressure, Pa at 30°C: 20
    Relative vapour density (air = 1): 5.44
    Flash point: 127°C c.c.
    Octanol/water partition coefficient as log Pow: 2.39
    ENVIRONMENTAL
    DATA
         		The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment.
    N O T E S
    Depending on the degree of exposure, periodic medical examination is indicated.
