Hi! I understand you're trying to view your boarding passes in the Southwest Airlines app on your Windows device, but it’s redirecting you to the hazardous materials page and not letting you go back. That definitely sounds inconvenient.

To help you better, can I ask:
- Are you using the Southwest Airlines app or the mobile website in your WebKit browser?
- Have you tried accessing your boarding pass in the app before or is this the first time?
- When exactly does the app take you to the hazardous materials page? After you tap “boarding pass” or at some other step?

Meanwhile, here’s a step-by-step approach that might resolve this based on common issues:

1. Force Close and Restart the App or Browser
Since you mentioned WebKit on Windows (which might mean you’re using a browser based on WebKit), try refreshing the browser completely. If it’s the app, close it fully and reopen.

2. Check for App Updates or Use Desktop Browser
Some app versions have had bugs causing this redirect. If available, update the Southwest app to the latest version. Alternatively, try checking in and viewing your boarding pass directly via the Southwest website on your browser.

3. Look for the Mandatory Hazardous Materials Info Confirmation
Southwest displays a hazardous materials info page that you must acknowledge before viewing boarding passes. Sometimes the page doesn’t scroll or the "OK" button to proceed is hidden, especially on certain devices or resolutions. Try scrolling carefully all the way down or resizing the window to find and tap the confirmation button.

4. Clear Browser Cache or App Data
If you’re using the browser, clear your cache and cookies for the Southwest site to remove any corrupted data causing loops. If app-based, clear the app cache or reinstall it.

5. Use an Alternative Device or Airport Kiosk
If none of the above work, you can print your boarding passes at Southwest kiosks located inside the airport entrance. They can print boarding passes if you provide your confirmation number and ID.

If after trying these steps you still hit that hazardous materials screen with no way to proceed, let me know and I can guide you through advanced troubleshooting or escalate this to our mobile app support team for immediate help.

Does this sound like a route worth trying? And feel free to tell me anything specific you’ve already done!
