Chemical Safety
0328 SULFAMIC ACID
IMPORTANT DATA
Physical State; Appearance Routes of exposure
ODOURLESS, COLOURLESS CRYSTALS OR POWDER. The substance can be absorbed into the body by inhalation of its
aerosol and by ingestion.
Chemical dangers
Inhalation risk
The substance decomposes on heating or on burning producing
toxic and corrosive fumes including nitrogen oxides and sulfur Evaporation at 20/C is negligible; a harmful concentration of
oxides. The solution in water is a strong acid, it reacts violently airborne particles can, however, be reached quickly when
with bases and is corrosive. Reacts violently with chlorine and dispersed, especially if powdered.
fuming nitric acid causing explosion hazard. Reacts slowly with
water to form ammonium bisulfate. Effects of short-term exposure
The aerosol is corrosive to the eyes, the skin and the respiratory
Occupational exposure limits tract. Inhalation of sulfamic acid aerosols may cause lung
TLV not established. oedema (see Notes).
PHYSICAL PROPERTIES
Melting point (decomposes): about 205/C Solubility in water: moderate (slow reaction)
Relative density (water = 1): 2.15
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 is therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in October 2005. See sections EU classification, Emergency Response.
