EXPOSURE
PREVENT GENERATION OF MISTS! AVOID ALL CONTACT!

  • INHALATION
    		• Cough. Sore throat. Symptoms may be delayed (see Notes).
    		Ventilation.
    		Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
  • SKIN
    		• Redness.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention. Wear protective gloves when administering first aid.
  • 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 induce vomiting. Rest. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Evacuate danger area! Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus).
    		Fireproof. Separated from strong oxidants, food and feedstuffs. Cool. Dry.
    		Airtight. Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic fumes (nitrogen oxides). Reacts with oxidants, acids, alcohols, amines, amides, mercaptanes. Attacks many metals, plastics, and rubber.

    OCCUPATIONAL EXPOSURE LIMITS (OELs):
     TLV: 0.005 ppm; 0.045 mg/m3 (skin) (ACGIH 1991-1992).
    OSHA PEL: none
    NIOSH REL: TWA 0.005 ppm (0.045 mg/m3) ST 0.02 ppm (0.180 mg/m3) skin
    NIOSH IDLH: No data


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

    INHALATION RISK:
     A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.

    EFFECTS OF SHORT-TERM EXPOSURE:
     The substance irritates the eyes, the skin and the respiratory tract. Inhalation of aerosol may cause asthmatic reactions (see Notes).

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization. Lungs may be affected by repeated or prolonged exposure (sensitization).
    PHYSICAL
    PROPERTIES
    Boiling point at 13.3 kPa: 216°C
    Melting point: -60°C
    Relative density (water = 1): 1.06
    Solubility in water: reacts
    		 Vapour pressure, Pa at 20°C: 0.04
    Flash point: 155-161°C
    Auto-ignition temperature: 430°C
    ENVIRONMENTAL
    DATA
    NOTES
    Explosive limits are unknown in literature. The applying occupational exposure limit value should not be exceeded during any part of the working exposure. The symptoms of asthma 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. Anyone who has shown symptoms of asthma due to this substance should never again come into contact with this substance. The odour warning when the exposure limit value is exceeded is insufficient.
