How should you react to someone who collapses from inhaling welding fumes?

When someone collapses from inhaling welding fumes, the immediate priority is to ensure their safety and provide prompt assistance. Moving them to fresh air is vital because it helps to alleviate the effects of the toxic fumes and could prevent any further complications. As welding fumes can contain harmful substances, ensuring the person is in a well-ventilated area reduces their exposure and aids in their recovery.

Seeking medical assistance is essential as well because, depending on the severity of the exposure, the individual may need specialized care. Symptoms of inhalation can vary and may not be immediately apparent, so professional evaluation is necessary to rule out any serious medical conditions.

In contrast, leaving the person until they regain consciousness could lead to further complications, as they may require immediate intervention. Using cold compresses is not appropriate in this situation because it does not address the root cause of the collapse, which is due to fumes rather than heat-related issues. Additionally, administering first aid without seeking professional help could be inadequate and potentially harmful if the person's condition worsens; it's crucial to ensure they receive the appropriate medical evaluation after such an incident.
