Warnsman

The warnsman was a colonist on Frontios.

Biography
The warnsman's job was to keep an eye out for signs of meteorite bombardments, and to warn the colonists.

However, when he spotted Tegan Jovanka, Vislor Turlough and Chief Science Officer Range's daughter Norna lowering an acid jar over the side of the ship, he shouted that they were not allowed up there and ran over to confront them.

The warnsman was knocked out by the swinging jar and therefore unable to warn the colonists about the darkening sky, which was a sign of a forthcoming bombardment. He was helped to the medical shelter by Norna shortly before the bombardment began. (TV: Frontios)
