The English subtitles are in my opinion annoying:

A lot of the joke comes from the fact that the narrator uses "overly technical" terms that are common for work (safety) instructions, but are otherwise barely used in everyday speech - mixed with much more colloquial wording (also, of course, when the workers are talking).

This mixture of two very different language registers (words mainly used in technically precise work safety instructions vs. colloquial talk) is not represented in the English subtitles and thus removes a lot of fun of the original German short film.
