Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

· Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.

Excerpt from ERG Guide 154 [Substances - Toxic and/or Corrosive (Non-Combustible)]:

· TOXIC and/or CORROSIVE; inhalation, ingestion or skin contact with material may cause severe injury or death.

Hydrolyzed by water evolving small amounts of heat and sulfuric acid; Toxic by ingestion; [CAMEO] Causes ciliary function changes in 60-minute inhalation study of rabbits; [RTECS] Causes burns; Inhalation may cause corrosive injuries to upper respiratory tract and lungs; [Aldrich MSDS]

Acidic salts, such as AMMONIUM HYDROGEN SULFATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
