Security Screening Questions? For questions on the rules for liquids in carry-on, sharp objects, weapons, tools, medicines and medical devices, food, "prohibited items," and general security screening questions, see the TSA's security rules and guidance. You may also contact the TSA via phone, e-mail or Tweet.

The Transportation Security Administration also has rules on "prohibited items" that pose a security threat. Though they sometimes overlap, the TSA security rules are separate from the FAA hazmat safety rules discussed here. For the TSA rules on weapons, sharp objects, the "3-1-1" rule on liquids, gels, and aerosols, etc.; go to the TSA Prohibited Items web page.
