Is it okay to store my collections in the basement/attic/garage if I put them in plastic bags or bins?

Do not store objects of value in the basement, attic, or garage. These areas are unsuitable for safely storing collections because of poor temperature and relative humidity control and higher risk of leaks and floods.

Polyethylene or polypropylene bags or bins are useful as a secondary protection against water damage (first protection is avoiding areas of higher water risk), but do not offer protection against the deteriorating effects of environmental extremes found in basements/attics/garages. In addition, the combination of a plastic storage container in an area of high humidity increases mold risk.
