Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: use appropriate extinguishing media. EXPLOSION EXPOSURE  •INHALATION Local exhaust or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Rinse skin with plenty of water or shower.  •EYES Redness. Pain. Safety goggles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Do not eat, drink, or smoke during work. Rinse mouth. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into covered containers. Then wash away with plenty of water. Personal protection: P2 filter respirator for harmful particles. Dry. Well closed. Separated from strong oxidants, acids.

International Chemical Safety Cards AMMONIUM SULFAMATE ICSC: 1555 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS TO WHITE HYGROSCOPIC CRYSTALLINE POWDER PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating above 160°C producing ammonia , nitrogen oxides and sulfur oxides . The solution in water is a weak acid. Attacks mild steel. Contact with hot water may cause formation of large amounts of steam. Reacts with acids and strong oxidants . OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 mg/m³ as TWA; (ACGIH 2004). MAK: IIb, value not established but data is available (DFG 2004). ROUTES OF EXPOSURE: INHALATION RISK: A harmful concentration of airborne particles can be reached quickly on spraying or when dispersed, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes . EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point (decomposes): 160°C Melting point: 131°C Relative density (water = 1): 1.8 Solubility in water: very good Vapour pressure, Pa at 20 °C: negligible ENVIRONMENTAL DATA N O T E S ADDITIONAL INFORMATION ICSC: 1555 AMMONIUM SULFAMATE (C) IPCS, CEC, 1994
