Phosphine gas

Hilda Abreu Utermohlen inquires regarding the effects of phosphine
fumigant on cultural materials. This gas is so rarely used in
museum, library, and archival fumigation that not a lot is known.
However, what is certain is that it does cause corrosion of metals
and the various manufacturers recommend that steps be taken to
protect metal materials during routine fumigation.

Her suggestion of anoxic treatment--if any treatment is
needed--seems far more appropriate.
