Which of the following is not considered a pneumatic safety rule?

The statement indicating that using any container for compressed air is not considered a pneumatic safety rule is accurate because the use of inappropriate or unsuitable containers can pose significant safety risks. Compressed air requires specifically designed containers that can withstand high pressures without rupturing or failing. Using makeshift or improper containers can lead to accidents, such as explosions or flying debris, which can severely injure individuals in the vicinity.

In contrast, the other safety rules emphasize protecting individuals and ensuring safe practices when handling compressed air. Not pointing compressed air at eyes prevents accidental injury to vision. Using pressure when cleaning with air is potentially harmful, and thus, caution should be taken. Wearing safety glasses is a fundamental safety rule to protect one's eyes when working with compressed air, further highlighting the importance of maintaining safety within pneumatic operations.
