What should you do if you find someone with a piece of glass sticking out of their arm?

Applying a dressing over the glass without applying pressure is the appropriate response in this situation. This approach helps protect the wound and minimizes the risk of the glass moving and causing further injury. It allows for safe transportation of the injured person to medical assistance without exacerbating the injury.

By avoiding direct pressure on the glass, you reduce the chances of it penetrating deeper into the tissue or causing additional bleeding. It's essential not to remove the glass, as this could lead to more severe bleeding and complications. Bandaging the arm tightly is also not advisable, as it could cut off circulation or increase pain without addressing the underlying issue. In emergencies like this, controlling the situation with the right technique ensures the best possible outcome for the injured person until professional medical help can be obtained.
