Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Which items should not be disposed of using a trash compactor?

1. Paper

2. Liquid dyes

3. Metal soft drink cans

4. Plastic bottles

The correct answer is: Liquid dyes

Liquid dyes should not be disposed of using a trash compactor because they can pose serious safety and environmental hazards. Compacting liquid substances can lead to leakage, which may contaminate other waste, create slippery conditions, or lead to chemical reactions that are dangerous. Moreover, many liquid dyes may be classified as hazardous waste, requiring special disposal methods to comply with regulations. On the other hand, items like paper, metal soft drink cans, and plastic bottles are typically considered safe for disposal in a trash compactor as they are solid materials that can be compacted without generating any hazardous conditions. By compacting these materials, you can reduce volume and manage waste more efficiently. In contrast, liquid substances require specific handling and disposal procedures to ensure compliance with safety standards and environmental regulations.
