LOS ANGELES - Condoms might be the only thing porn actors are required to wear if the state's workplace safety board approves a petition mandating their use.

In a hearing Thursday, the California Occupational Safety and Health Standards Board will hear testimony from the Los Angeles-based AIDS Healthcare Foundation. The advocacy group filed a petition in December to require condoms be used in porn.

The advocacy group wants the same sort of workplace protections in place for nurses and doctors to be extended to porn, to protect actors from sexually-transmitted diseases like HIV.

By law, U.S. adult film actors must prove they have tested negative for HIV and other sexually transmitted diseases within 30 days of going to work on a film.
