Which hazard arises from improper use of compressed air, specifically related to user behavior?

The hazard that arises from the improper use of compressed air, particularly in relation to user behavior, is internal overpressures. When compressed air is mishandled, such as using it for cleaning purposes or directing it towards body parts, it can lead to the risk of air entering the body through openings like the ears or skin. This may cause air embolisms or other serious internal injuries due to an increase in internal pressure within the body.

Understanding this risk emphasizes the importance of following proper protocols when using compressed air. It is crucial for users to be aware of safe practices to prevent such overpressures from occurring, which can ultimately protect their health and safety in the workplace.
