FIRE FIGHTING
FIRE Flammable.
NO open flames, NO sparks, and NO smoking. NO contact with oxidants.
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
EXPLOSION Above 26°C explosive vapour/air mixtures may be formed.
Above 26°C closed system, ventilation, and explosion-proof electrical equipment.

EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
  • INHALATION
    		• Corrosive. Burning sensation. Cough. Laboured breathing.
    		Ventilation, local exhaust, or breathing protection.
    		Fresh air, rest. Half-upright position. Refer for medical attention.
  • SKIN
    		• Corrosive. Redness. Pain. Blisters.
    		Protective gloves. Protective clothing.
    		Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
  • EYES
    		• Corrosive. Redness. Pain. 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
    		• Corrosive. Abdominal cramps. Burning sensation. Vomiting. Collapse.
    		Do not eat, drink, or smoke during work.
    		Rinse mouth. Refer for medical attention.
    SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
    Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place (extra personal protection: self-contained breathing apparatus).
    		Fireproof. Separated from strong oxidants, acids, food and feedstuffs.
    		Do not transport with food and feedstuffs.

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

    PHYSICAL DANGERS:
     The vapour is heavier than air.

    CHEMICAL DANGERS:
     The substance decomposes on heating producing toxic gases (nitrogen oxides). The substance is a strong base, it reacts violently with acid and is corrosive. Reacts violently with strong oxidants causing fire hazard.

    OCCUPATIONAL EXPOSURE LIMITS:
     TLV: 10 ppm; 41 mg/m3 (as TWA) (ACGIH 1992-1993).
    PDK: 1 mg/m3 (USSR 1993).
    OSHA PEL: none
    NIOSH REL: TWA 10 ppm (40 mg/m3)
    NIOSH IDLH: No data


    		ROUTES OF EXPOSURE:
     The substance can be absorbed into the body by inhalation 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:
     Corrosive. The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). The effects may be delayed.

    EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
     Repeated or prolonged contact may cause skin sensitization.
    PHYSICAL
    PROPERTIES
    Boiling point: 134°C
    Melting point: -18°C
    Relative density (water = 1): 0.9
    Solubility in water: good
    Vapour pressure, kPa at 20°C: 1.2
    		Relative vapour density (air = 1): 3.4
    Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03
    Flash point: (c.c.) 26°C
    Auto-ignition temperature: 293°C
    Explosive limits, vol% in air: 1.5%-9.4%
    ENVIRONMENTAL
    DATA
    NOTES
    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.
