EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
  • Burning sensation. Cough. Headache. Laboured breathing. Nausea. Vomiting.
    Local exhaust or breathing protection.
    Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
  • MAY BE ABSORBED! Redness. Pain. Blisters.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
  • EYES
  • 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
  • Abdominal cramps. Burning sensation. Collapse.
    Do not eat, drink, or smoke during work.
    Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    Separated from strong oxidants, food and feedstuffs.
    Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
    COLOURLESS OR YELLOW LIQUID OR CRYSTALS , WITH CHARACTERISTIC ODOUR. TURNS DARK ON EXPOSURE TO AIR AND LIGHT.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    Reacts violently with strong oxidizing agents, causing fire and explosion hazard.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV: 5 ppm; 22 mg/m3 (as TWA) (skin) (ACGIH 1993-1994).
    MAK: 5 ppm; 22 mg/m3; skin (1992).


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

    INHALATION RISK:
    A harmful contamination of the air can be reached rather quickly 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 vapour or aerosol may cause lung oedema (see Notes). The substance may cause effects on the central nervous system and various organs.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
    Repeated or prolonged contact with skin may cause dermatitis.

    ENVIRONMENTAL
    DATA
    This substance may be hazardous to the environment; special attention should be given to water. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
    N O T E S
    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.
