Building Sites Bite is a 1978 British short public information film produced by the Central Office of Information for the Health and Safety Executive and the Mighty Movie Company for British schools to warn children about the dangers of playing on building sites.

Building Sites Bite was filmed as party of a national campaign responding to the deaths of more than 20 children in 1977 in building-site accidents.

His cousins Paul and Jane decide to test Ronald's know-it-all attitude by teleporting him to a building site, where he must avoid several hazards and obstacles without getting hurt.

Imagining himself and his sister as silver-suited cosmic overlords, he inflicts multiple imaginary deaths on his cravat-sporting nemesis by transporting him (via a garden shed TARDIS) to a succession of deserted building sites.

Here, exposed electrical cables and collapsing walls repeatedly nudge Ronald from an increasingly thankless mortal coil.
