PREVENT GENERATION OF MISTS!

  • INHALATION
    		• Cough. Sore throat.
    		Ventilation.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness. Pain.
    		Protective gloves.
    		First rinse with plenty of water, then remove contaminated clothes and rinse again.
  • EYES
    		• Redness. Pain.
    		Safety spectacles.
    		First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
  • INGESTION
    		• Abdominal pain. Burning sensation. Cough. Diarrhoea. Sore throat. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Give plenty of water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Ventilation. Wash away spilled liquid with plenty of water. Do NOT absorb in saw-dust or other combustible absorbents. In case of a large spillage use (extra personal protection: self-contained breathing apparatus).
    		Separated from acids. See Chemical Dangers. Cool. Keep in the dark. Well closed.

    PHYSICAL STATE; APPEARANCE:
     CLEAR, SLIGHTLY YELLOW SOLUTION , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating, on contact with acids and under influence of light producing toxic and corrosive gases including chlorine (see ICSC # 0126). The substance is a strong oxidant and reacts with combustible and reducing materials. The solution in water is a weak base.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV not established.


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

    INHALATION RISK:
     No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C.

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

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization.
    PHYSICAL
    PROPERTIES
    Relative density (water = 1): 1.1 (5.5% aqueous solution)
    ENVIRONMENTAL
    DATA
         		The substance is toxic to aquatic organisms.
    N O T E S
    Household bleaches usually contain about 5% sodium hypochlorite (about pH11, irritant), and more concentrated bleaches contain 10-15% sodium hypochlorite (about pH13, corrosive). Rinse contaminated clothes (fire hazard) with plenty of water. Clorox and Javel water are trade names. Also consult ICSC # 1119 (Sodium hypochlorite, active chlorine >5%).
