NO open flames. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Above 74°C explosive vapour/air mixtures may be formed. Above 74°C use a closed system, ventilation. EXPOSURE AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •INHALATION Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.  •SKIN Pain. Redness. Blisters. Skin burns. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.  •EYES Pain. Redness. Severe deep burns. Loss of vision. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Burning sensation. Abdominal pain. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking liquid in sealable containers. Cautiously neutralize remainder. Then wash away with plenty of water. Personal protection: complete protective clothing including self-contained breathing apparatus. Separated from strong oxidants, acids.

International Chemical Safety Cards N-METHYLETHANOLAMINE ICSC: 1336 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: VISCOUS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including nitrogen oxides . The substance is a strong base, it reacts violently with acid and is corrosive. Reacts with strong oxidants. Attacks many metals. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached 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: PHYSICAL PROPERTIES Boiling point: 156°C Melting point: -4.5°C Relative density (water = 1): 0.93 Solubility in water: miscible Vapour pressure, kPa at 20°C: 0.93 Relative vapour density (air = 1): 2.6 Flash point: 74°C o.c.
