(AP) — Teenagers younger than 16 years old may soon be restricted from using indoor tanning beds in Nebraska.

Lawmakers on Tuesday gave first-round approval to a bill designed to reduce skin cancer risks. The bill by Sen. Jeremy Nordquist of Omaha would also require tanning facilities to post a sign warning that overexposure to ultraviolet radiation can cause premature skin aging and skin cancer.

Senators added an exemption for young teens if they are accompanied by a parent, and the parent signs a permission form each time their child tans.

The bill advanced on a 34-0 vote. The original legislation would have imposed a ban on users younger than 18.
