Your original question opens a very large door.
First, pedestrian employees in order to be "competent" must be made aware of the dangers to their health & safety connected with the assigned work. This should be part of their orientation package - their do's and don't's working around lift trucks. This comprises many different topics. If you'd like to contact me off-line ([email address removed]), I'd be pleased to fax you a copy of my 2 page Pedestrian Safety Manual that I pass out when I do my courses.
Second, at all blind corners, doorways, inter-sections, any place there could be a collison between a lift truck and another object or person, there must be an overhead mirror.
Back up alarms are a requirement in some Provinces/State, but even so: all lift trucks should have a flashing light that is mounted to the top of the driver's overhead guard and be flashing at all times - come on with the key.
Also, headlights and a back up light are mandatory when used after dark or in dimly lit areas, but my recommendation is 2 headlights that come on with the key, "daytime running lights" and the reverse light should come on when the unit is put in reverse - not by a separate swith.
Pedestrians can see the reflection of a light in an overhead mirror before they see the reflection of a lift truck. Also, at blind corners, inter-sections and doorways, a light may be seen shining off walls/boxes/racks even before a lift truck can be seen.
Lift truck operators must be told that at all blind corners, doorways, inter-sections and when they make a turn that: they must slow down to a yield speed, sound their horn and yield right-of-way.
Back up alarms must be audible over any background noise. The loudest I've seen is 120Db. In a noisy application, make sure you have the loudest back up alarm available and it's located for maximum sound (not under an engine or battery hood as example).
For forward travel, you can purchase a bell alarm that attaches to the wheel assembly. Each revolution creates a bell - the faster the lift truck is going, the more "bells" that go off.
Pedestrian safety garments: lift truck drivers that hit a pedestrian usually say, "I didn't see him or, I didn't see him in time." Consider safety garments, i.e. vests or something else. There is a relatively new standard in the U.S. and one in Canada as well with different classifications for different applications.
Pedestrian sidewalks painted on the floor keep pedestrians in a certain area and not all over. Drivers stay off the "sidewalks" and.....some Companies paint 2 lines on the floor to designate a lift truck highway so, all said and done, you have a separate area for lift trucks and pedestrians to eliminate or reduce collisions.
Yield or Stop Lines painted on the floor can also remind lift trucks and pedestrians to yield at a blind area.
These are just a few of the ideas to respond to your inquiry. Hope they may help.
