Curb Ramps are not Ramps. Oddly, there seems to be some confusion about this.
To keep it simple, if there is no curb, it’s a ramp.
But to answer all of those questions that go beyond “keeping it simple” print out 50 copies of CurbRampVRamps and glue them liberally to desks throughout your office.
Your coworkers will thank you.

Accessible ramps and ramp landings require edge protection to prevent users from slipping off of the ramped surface.
TAS 4.8.7 Edge Protection. Ramps and landings with drop-offs shall have curbs, walls, railings, or projecting surfaces that prevent people from slipping off the ramp. Curbs shall be a minimum of 2 in (50 mm) high (see Fig. 17).
Accessible routes with slopes of 5% or less are not considered ramps and do not require edge protection even if there is a drop off.
Also, curb ramps do not require edge protection.
Remember, these standards are only a minimum requirement. If you have a sidewalk with a drop-off that you believe could be a hazard, some sort of barrier may be advised. Just be sure that you don’t create a trip hazard.
And, the building code will usually require guards when you have a drop-off greater than 30″.
