In 1966, the Federal government mandated that cigarette packs have a warning on them from the surgeon general. In 1973, Congress decided that products containing “toxic substances” must have labels. In 1985, a testimony was made alongside demands for record companies to put labels on music that contained sexual or violent lyrics. On March 29, 1990, warning labels were put on music products that contained potentially offensive lyrics; this was done with the agreement of the recording companies. In 1989, alcohol was required to have the surgeon general’s warning.
There are three levels of labelling; caution, warning and danger:[2]
Caution indicates a potentially hazardous situation that, if not avoided, may result in minor or moderate injury.
Warning indicates a potentially hazardous situation that, if not avoided, could result in death or serious injury.
Danger indicates an imminently hazardous situation that, if not avoided, will result in death or serious injury. This word is limited to the use in the most extreme situations.
