What ventilation requirements apply to a warehouse? Is a fresh-air system required?

A medicine warehouse ventilation system is important for maintaining suitable storage conditions and staff health. The basic requirement is to ensure air circulation and avoid dead spots or stagnant air. This helps maintain uniform temperature and humidity throughout the warehouse and remove any odours or volatile gases that may accumulate. For most warehouses storing only ordinary packaged medicines, good natural or mechanical ventilation (such as exhaust fans) is generally sufficient. However, if your warehouse is fully enclosed with no windows, or if the medicines you store release dust or volatile organic compounds (VOCs), installing a fresh air system capable of supplying fresh, filtered air becomes essential. This not only improves air quality but can also create positive indoor pressure, reducing the entry of external contaminants.
