Identify on a facility floor plan all the locations where chemicals are stored, and list the chemicals in each. You may be surprised at the amount or kinds of chemicals. Some may be beyond their shelf life, obsolete or simply too large a quantity for current needs. Document handling methods and best route from the receiving dock to each location. This area requires increasing vigilance.
Stewardship has much greater consequences now than ever before.
Beyond that, know the law. Also, get references. OSHA instituted a prioritizing process in 1994. You can use these same techniques in your facility. Your priorities may not be the same as OSHA's because you might have different risks.
