The only safty reg I know of pertains to the 15-pin DB-mini connector for the 'AUI' interface: Safety agencies require a fuse (or current-limiting) on AUI Pin 13 which sources 12 volts. Otherwise they consider the AUI 'hazardous', requiring all sorts of stickers and warnings.
ANSI/IEEE 802.3 specifies 300mA source capability for the AUI but not all AUI interfaces are 802.3 compliant; they may source less than 300mA. Review all power supply outputs (PC card, custom adapters) to verify they are limited-current per EN 60950.
