OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at http://www.osha.gov.

Dear Mr. Wiedenhoefer:
Inside storage rooms must be provided with either a gravity or a continuous mechanical exhaust ventilation system. The system shall be designed to provide for a complete change of air within the room at least six times per hour. If mechanical ventilation is provided, the make-up air may be taken from within the building but the opening shall be equipped with an approved fire door or damper.
Please contact us if we can be of further service. You may call toll-free at 800-621-0523.
