 PRECAUTIONS WHEN WORKING ALOFT

As we mentioned earlier, it is extremely important to follow all safety precautions when working aloft. Before you work on an antenna, ensure that it is tagged out properly at the switchboard to prevent it from becoming operational. Always be sure to secure the motor safety switches for rotating antennas. Have the switches tagged and locked open before you begin working on or near the antenna.

When working near a stack, draw and wear the recommended oxygen breathing apparatus. Among other toxic substances, stack gas contains carbon monoxide. Carbon monoxide is too unstable to build up to a high concentration in the open, but prolonged exposure to even small quantities is dangerous.
