Storage and

Workers should wear personal protective equipment and avoid contact with skin, eyes, and clothing. Workers must avoid breathing dusts, wash thoroughly after handling, and use with adequate ventilation. Contaminated clothing should be laundered before reuse.

Ammonium sulfate should be stored in a cool, dry area, away from strong oxidizers. For exposure control and personal protection, natural or mechanical ventilation sufficient to maintain levels below the recommended exposure levels should be provided. In adequately ventilated areas, respiratory protection is not required. For exposure above the threshold limit value (TLV), a NIOSH-approved dust respirator should be used.

For eye protection, indirectly vented safety goggles are recommended against nuisance dust containing ammonium sulfate. Workers handling such dust should not wear contact lenses. For skin protection, workers handling ammonium sulfate should wear long-sleeved shirt and pants or coveralls and work gloves to minimize skin contact. An eyewash station and safety shower should be provided that are convenient to the work area.

Ammonium sulfate should not be stored or used near oxidizers, peroxides, potassium chlorate, potassium nitrate, sodium nitrate, metal chlorates, and strong bases. It is corrosive to carbon steel, copper, and copper alloys and should not be heated above 100°C to avoid decomposition (10-12).
