Recently,
many offices have inquired about the duration of Material Safety Data Sheets
("MSDS") that need to be kept for products that are no longer used. Just as a
reminder, you do not need to keep MSDS files for products no longer in use.
Keep in mind however that you need to keep either the
MSDS, chemical inventories, or any other records that reveal where and when a
product was used along with the identity (e.g., chemical, common, or trade
name) of all toxic substances or harmful physical agents.
