Mold, mildew and flammability?
Due to the nature of the materials used and the drainage base designed to migrate water away from the turf, mold and mildew is not an issue. Generally speaking, the turf is much less flammable than live natural grass (and many times less flammable that dead natural grass). The sand and rubber infill also helps to prevent a fire from spreading, and can often extinguish a fire.
