Effects of long-term or repeated exposure
Lungs may be affected by repeated or prolonged exposure to
the vapour or aerosol.
PHYSICAL PROPERTIES
Boiling point: (25%) 38/C Solubility in water: miscible
Melting point: (25%) -58/C Vapour pressure, kPa at 20/C: (25%) 48
Relative density (water = 1): (25%) 0.9 Relative vapour density (air = 1): 0.6-1.2
ENVIRONMENTAL DATA
The substance is very toxic to aquatic organisms.
NOTES
Ammonia vapour is flammable and explosive under certain conditions. Be aware that ammonia gas can evolve from ammonia
solution.
Depending on the degree of exposure, periodic medical examination is suggested.
Do NOT completely fill bottles with the substance; strong solutions may develop pressure. Release caps with care.
Other UN numbers are: UN 1005 Ammonia, anhydrous liquefied or ammonia solutions, relative density of less than 0.880 at 15/C in
water, with more than 50% ammonia; UN 2073 Ammonia, 35-50%.
Also consult ICSC 0414 Ammonia.
Card has been partly updated in October 2004. See sections Occupational Exposure Limits, EU classification, Emergency
Response.
