[header] How to control environmental pollution risks in a hospital [title] Accurately record your inventory. [step] Keep careful track of the inventory of materials you have on hand in the hospital for future use. Avoid overstocking items that have limited lifespans, as these will need to be disposed of. 
[substeps] Perform quarterly inventory checks to look for items that are close to the end of their lifespans. A computerized inventory system will make this task much easier.
