FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking.
Foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

  • INHALATION
    		• Cough. Drowsiness. Headache. Shortness of breath. Sore throat. Unconsciousness.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse and then wash skin with water and soap.
  • EYES
    		• Redness. Pain.
    		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
    		• Nausea. Vomiting.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. 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 wash away into sewer.
    		Fireproof. Separated from strong oxidants, strong bases, strong acids. Cool. Keep in the dark. Keep in a well-ventilated room. Store only if stabilized.

    PHYSICAL STATE; APPEARANCE:
     COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

    PHYSICAL DANGERS:
     The vapour is heavier than air and may travel along the ground; distant ignition possible. The vapour mixes well with air, explosive mixtures are easily formed. Vapours are not inhibited, they may polymerize and block the vents.

    CHEMICAL DANGERS:
     The substance may polymerize due to warming or due to heating under the influence of light, polymerization catalysts and strong oxidants with fire or explosion hazard. Reacts with strong acids, strong bases and oxidants.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 100 ppm; 410 mg/m3 (as TWA) (ACGIH 1994-1995).
    MAK: 50 ppm; 210 mg/m3; I, A II (1993).


    		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 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. Repeated or prolonged inhalation exposure may cause asthma. The substance may have effects on the central nervous system and the peripheral nervous system.

    ENVIRONMENTAL
    DATA
         		This substance may be hazardous to the environment; special attention should be given to water.
    N O T E S
    Usually contains hydroquinone, hydroquinone methyl ether and dimethyl t-butylphenol as inhibitors of polymerization. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
