What should you do if a coworker feels a heavy weight on his chest and has trouble breathing?

In a situation where a coworker is experiencing a heavy weight on his chest and has trouble breathing, it is crucial to prioritize his immediate safety and well-being. Allowing him to find a position of comfort is a key step, as it can help alleviate some of his distress and make it easier for him to breathe. Activating emergency medical services (EMS) is vital because symptoms like these could indicate a serious condition such as a heart attack or severe respiratory issue, which requires professional medical attention.

By taking both actions together—supporting him in finding a comfortable position and promptly activating EMS—you ensure that the coworker is as stable as possible while awaiting help. This approach emphasizes the importance of both comfort measures and timely medical intervention in responding to potentially life-threatening situations.
