Manufacturing Skill Standards Council (MSSC) Safety Assessment Practice Test

Which type of material must be clearly labeled before shipping?

1. Soap

2. Scrap steel

3. Plastic pellets

4. Flammable

The correct answer is: Flammable

Materials that are classified as flammable pose significant risks during handling and transportation, making it essential for them to be clearly labeled before shipping. Proper labeling serves as a warning to those who might come into contact with the materials, informing them of the potential hazards and ensuring that appropriate safety precautions are taken to prevent accidents such as fires or explosions. In industries that deal with hazardous materials, labeling must comply with regulatory standards and guidelines such as those stipulated by OSHA (Occupational Safety and Health Administration) and the DOT (Department of Transportation). These regulations require that flammable substances be marked with specific labels indicating their nature and the precautions necessary to handle them safely. For the other materials listed, while they may have their own safety considerations, the requirement for clear labeling is particularly critical for flammable materials due to the heightened risks associated with their transportation and storage.
