Manufacturers of Citizen Band and antennas will have to adhere to a new set of federal safety regulations which were approved yesterday following reports that more than 500 persons have died two years in antenna-related accidents.

The Consumer Product Safety Commission now requires red and yellow labels on the antennas warning users that they can be killed if the antenna comes in contact with overhead power lines during installation.

According to the CPSC, antenna mishaps are the number one cause of electrocutions among consumer products.

Besides the warning labels, the new regulations will require the estimated 150 manufacturers of CB base station (home) antennas, television antennas, and certain antenna-supporting structures to include safety installation instructions and written information on hazards. Some 85 percent of the manufactueres already use the warning labels.

The added cost to the consumer for the new requirements will be about $1 an antenna, the CPSC said, although manufacturer cost is estimated at only 35 cents.

CPSC staffers are studying whether to require installation of heavy-duty insulation device on each antenna to protect the installer if the antenna comes in contact with a power line.

The commission had 500 reported deaths relating to antenna installation in 1975 and 1976, and said the number is increasing every year because of the growing interest in CB radios.
