Key points in this article
Two extremes to avoid
One side fears spacing too much; the other ignores it. The sound choice treats safety as a precondition decided before installation, not a reaction after an incident has already caused harm or delay to someone.
Details to align early
Check whether base conditions match, who handles anomalies, and where responsibility lies. In Yantai districts these points have caused confusion before; aligning them early saves rework and protects both sides from blame.
The right sequence on site
When a spacing concern appears, stop first, report second, and keep evidence third. Writing responsibilities into the agreement protects both the service side and the user, and keeps cooperation steady and honest.
