By law, pedestrians or vehicles must be able to use a traffic route without causing danger to the health or safety of people working near it, this equally applies inside and outside of your warehouse.
Roadways, forklift lanes and pedestrian footpaths should be separate whenever possible.
You need to consider protection for people who work near vehicle routes.
By law, traffic routes must also keep vehicle routes far enough away from doors or gates that pedestrians use, or from pedestrian routes that lead on to them, so the safety of pedestrians is not threatened.
Where pedestrian and vehicle routes cross, provide appropriate crossing points for people to use. Pedestrians, cyclists and drivers should be able to see clearly in all directions. Crossing points should be suitably marked and signposted, and should include dropped kerbs where the walkway is raised from the driving surface.
Where necessary, provide barriers or rails to prevent pedestrians from crossing at dangerous points and to direct them to the crossing places. Similarly, you can use deterrent paving to guide pedestrians to the crossing points.
At busy crossing places, consider traffic lights, zebra crossings (or other types of crossing), or suitable bridges or subways as a way of segregating pedestrians from moving vehicles.
