FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, AFFF, foam, carbon dioxide.
EXPLOSION Above 43C explosive vapour/air mixtures may be formed.
Above 43C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


  • INHALATION
  • Cough. Dizziness. Headache. Nausea. Unconsciousness. Vomiting. Weakness.
    Ventilation, local exhaust, or breathing protection.
    Fresh air, rest. Refer for medical attention.
  • SKIN
  • Redness.
    Protective gloves. Protective clothing.
    Remove contaminated clothes. Rinse skin with plenty of water or shower.
  • EYES
  • Redness.
    Safety goggles 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

  • Do not eat, drink, or smoke during work.
    Rinse mouth.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! 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. Carefully collect remainder (extra personal protection: self-contained breathing apparatus).
    Fireproof. Separated from reducing agents, alkali metals, strong oxidants.
    Airtight. Unbreakable packaging; put breakable packaging into closed unbreakable container.
    UN Hazard Class: 3
    UN Packing Group: III

    PHYSICAL STATE; APPEARANCE:
    LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:


    CHEMICAL DANGERS:
    The substance decomposes on burning producing highly toxic gases including sulfur dioxide (see ICSC # 0074). Reacts with strong oxidants, reducing agents, and alkali metals.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
    TLV not established.
    MAK not established.


    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 very quickly on evaporation of this substance at 20C.

    EFFECTS OF SHORT-TERM EXPOSURE:
    The substance irritates the eyes, the skin, and the respiratory tract. The substance may cause effects on the central nervous system , resulting in respiratory failure.

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