False When lifting heavy objects like cylinders, using improper techniques can lead to serious injury. It is crucial to follow safe lifting practices. Here are some tips for safely lifting and carrying a cylinder without a lifting aid: 1. **Assess the weight and path:** Ensure the cylinder is not too heavy for you to lift alone and that the path is clear of obstacles. 2. **Use your legs, not your back:** Squat down by bending your knees and keeping your back straight. Grip the cylinder firmly. 3. **Maintain proper posture:** Keep your back straight, hold the cylinder close to your body, and use your leg muscles to lift, not your back. 4. **Avoid twisting:** Once you have the cylinder lifted, avoid twisting your body. Instead, move your feet to turn. 5. **Team lift:** If the cylinder is too heavy to lift alone, enlist the help of another person to avoid injury. Always prioritize your safety and, whenever possible, use proper equipment designed for lifting heavy objects.
