Use a bosun-s chair and safety line when working aloft.
Tie off tools and parts when working aloft so they won-t drop and injure those below.
Make sure radar is turned off when working aloft. Radio antennae and radar scanners emit radiation, and a rotating scanner can cause serious injuries.
When anyone working aloft, place a sign "Do Not Operate Radar" on the radar control panel.
