Which item is considered a non-permissible material for the trash compactor?

Liquids are classified as non-permissible materials for the trash compactor due to safety and operational concerns. When liquids are placed in the compactor, they can create a hazardous environment by increasing the risk of spills and contamination. Additionally, liquids can affect the compactor's functionality by causing clogs or malfunctions, leading to potential damage to the equipment. Proper disposal methods are crucial in preventing overwhelming damage to the compactor and ensuring a safe work environment. Other materials, such as plastic containers, food wrappers, and cardboard boxes, typically fall within acceptable guidelines for compaction, provided they are handled according to specific waste management practices.
