FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 54░C explosive vapour/air mixtures may be formed.
Above 54░C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

  • INHALATION
    		• Burning sensation. Cough. Shortness of breath. Sore throat.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
    		• Skin burns. Pain. Blisters.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Redness. Pain. Blurred vision. Severe deep burns.
    		Face shield.
    		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. Nausea. Shock or collapse. Sore throat. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    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. Do NOT let this chemical enter the environment. (extra personal protection: chemical protection suit including self-contained breathing apparatus).
    		Fireproof. Separated from strong oxidants, strong bases, food and feedstuffs.
    		Do not transport with food and feedstuffs.

    PHYSICAL STATE; APPEARANCE:
     OILY COLOURLESS LIQUID , WITH PUNGENT ODOUR.

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance is a medium strong acid. Reacts with bases, strong oxidants and amines causing fire and explosion hazard. Attacks many metals forming flammable/explosive gas (hydrogen -- see ICSC # 0001).

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 10 ppm; 30 mg/m3 (ACGIH 1997).
    MAK: 10 ppm; 30 mg/m3; (1996)


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

    INHALATION RISK:
     A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20░C.

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

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
