What are the some of the issues with Pallet Storage? (323-324)

With multiple stacked pallets it is more difficult for water from a sprinkler to reach, wet, and control a fire.

- Air space between top and bottom layers of pallets (~4”) created significant fire hazard b/c provides path for promoting spread of fire
- Materials are often completely encapsulated in plastic wrap (cocooning)
- Plastic encapsulation prevents fire suppression system water from penetrating surface of stored material
- Packing/wrapping adds to the fuel load
- Pallets stacked several layers high prevent sprinkler water from reaching bottom layers
