ACUTE HAZARDS/
SYMPTOMS
PREVENTION FIRST AID/
FIRE FIGHTING
FIRE Not combustible. Many reactions may cause fire or explosion. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with combustible substances (see Chemical Dangers).

EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

  • INHALATION
  • Corrosive. Burning sensation. Cough. Shortness of breath.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
  • Corrosive. Redness. Pain. Blisters.
    Protective gloves. Protective clothing.
    First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
  • EYES
  • Corrosive. Redness. Pain. Severe deep burns.
    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
  • Corrosive. Abdominal cramps. Burning sensation. Unconsciousness. Vomiting. Weakness.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Ventilation. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT absorb in saw-dust or other combustible absorbents (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from acids, food and feedstuffs, and incompatible substances (see Chemical Dangers). Cool. Keep in the dark. Well closed.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    CLEAR, YELLOWISH-GREEN 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 violently with combustible and reducing materials causing fire and explosion hazard. The solution in water is a strong base, it reacts violently with acid and is corrosive. Attacks many metals.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.


    ROUTES OF EXPOSURE:
    The substance can be absorbed into the body by inhalation of its vapour and 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 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of aerosol may cause lung oedema (see Notes).

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact may cause skin sensitization (see Notes).
    PHYSICAL
    PROPERTIES
    Relative density (water = 1): 1.21
    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. Sodium hypochlorite is not a sentisizing agent, even if some allergic reaction may occur in rare cases. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Rinse contaminated clothes (fire hazard) with plenty of water. Chloros, Chlorox, Clorox, Deosan, Javex, Klorocin, Parozone and Purin B are trade names. Also consult ICSC # 0482 (Sodium hypochlorite, active chlorine 5%).
