Heat treating wooden ammunition pallets for invasive species
Snapshot: Wood pallets serve as support for munitions loads and other military supplies transported within the continental U.S. and internationally. Despite this integral transport function, wood pallets have been identified as a major pathway for the introduction and spread of non-native invasive insect species. Heat sterilization regulations help mitigate invasive species threats but concerns have arisen regarding possible effects of heat treatment on wooden pallets in terms of strength and durability. Green hardwood pallets undergoing treatment in heat chambers were emerging with various defects that exceeded specifications.
