Containers shall be constructed of durable rust- and corrosion-resistant material that is easy to clean. All containers shall be equipped with tight-fitting lids or doors to prevent entrance of insects or rodents. Doors and lids shall be constructed and maintained so they can be easily opened. Containers shall be water-tight, leak-proof and of weather-proof construction.
