Imagine there’s a military bombing range full of unexploded ordinance. The sign outside the range simply says “Keep off the grass”.
In the situation where context is different than what a reasonable person would expect, it has to be included. Language changes meaning depending on context.
The point is that language is unavoidably ambiguous (I'm sure there's a mathematical information theory proof of this, akin to the Byzantine Generals problem.).
"DANGER!! Unexploded ordinance! High risk of death!" is far less ambiguous than "Keep off grass". The former is sufficiently unambiguous that it will deter any sane person from entering.
