Appendix VI (Water Reactive Chemicals)

Some chemicals react with water and produce excessive heat, and flammable or toxic gases. Store under conditions that prevent contact with water. Some examples are listed below.

Acid anhydrides, e.g., acetic anhydride
Acid halides, inorganic, e.g., phosphoryl chloride, sulfuryl chloride
Acid halides, organic, e.g., acetyl chloride
Alkali metals
Alkali metal amides
Alkali metal hydrides
Anhydrous metal halides, e.g., aluminum trichloride
Calcium carbide
Grignard reagents
Metal alkyls
Non-metal halides, e.g., boron trifluoride, phosphorous trichloride
Phosphorous pentoxide
Sodium dithionite
