Storage Precautions for Pyrophorics
-
Store in a cool, dry place. Prevent contact with air.
-
Take extreme care to prevent containers of pyrophorics from leaking or breaking. The use of corrosion- and shatter-resistant secondary containers for storage and transportation of pyrophoric reagent bottles is encouraged.
-
Many pyrophorics are also water reactives (section 5.9).
Toxic gases, highly toxic gases, and pyrophoric gases must be managed in accordance with the campus Toxic, Corrosive and Pyrophoric (TCP)Gas Program requirements. Contact EH&S for details about ventilation and quantity limitations.
