Smarter Setup Guidance for Dangerous Site Stanchion Warnings

❌ Placement errors that reduce warning value

❌ Placing it after the hazard rather than before the approach
❌ Letting parked vehicles or skips hide the message face
❌ Angling it away from the route people actually use

❌ Situations where this is the wrong choice

❌ Do not use it as a substitute for barriers where access must be stopped

✅ Better installation decisions on active sites

✅ Face it towards the natural walking or vehicle approach
✅ Recheck the position after deliveries, plant movement or layout changes
✅ Pair it with barriers or supervision where people must be kept out
