Approach visibility matters
Position warning products along likely approaches while preserving accessible routes and required clearances.
Use enough signs for the space
Large or multi-directional areas may need more than one warning point. A single sign hidden behind a column cannot communicate to every approach.
Avoid creating a new obstruction
Signs should not narrow routes unnecessarily or introduce a trip hazard. Site conditions and accessibility requirements still apply.
Remove signs when the hazard is resolved
Overused signs can lose meaning. Clear them once the surface and surrounding conditions are safe under the facility’s procedures.
