Which of the following is NOT a guideline for maintaining personal health?

The option indicating "ignore PPE requirements" is not a guideline for maintaining personal health because ignoring Personal Protective Equipment (PPE) directly compromises both individual health and safety. PPE serves as a critical barrier against various hazards that firefighters and other emergency responders encounter, including physical injuries, toxins, and environmental dangers. Proper use of PPE enhances personal safety and tends to prevent health issues that can arise from exposure to these risks.

In contrast, the other choices emphasize proactive measures for maintaining health. Eating well provides the necessary nutrients to support overall health and physical performance. Working out fosters physical fitness, which is essential in fire service roles that require stamina and strength. Using correct lifting techniques prevents musculoskeletal injuries and enhances the firefighter's ability to perform effectively. Each of these actions contributes to maintaining optimal health, while ignoring PPE requirements undermines that goal entirely.
