Emerson filed a federal lawsuit in St. Louis on Monday, seeking to block the NBC television network from rebroadcasting the pilot episode of the new show "Heroes," which depicts a woman damaging her hand in a garbage disposal made by the company.

The Ferguson-based maker of electric products says NBC Universal Television Studios did not have the right to use the company's In-Sink-Erator brand disposal in the show without permission.

The filing comes complete with color printouts that show a re-creation of a woman putting her hand in the disposal and pulling it out mangled and bloody. The suit says the scene suggests that the Emerson In-Sink-Erator "will cause debilitating and severe injuries, including the loss of fingers, in the event consumers were to accidentally insert their hand into one."
