I recall seeing a CIR a few years that addressed this issue but I'm unable to retrieve it at the Interpretations Database. Issue: we have an institutional cafeteria that has doors leading outside to a paved terrace/patio. I presume we need to provide walk-off mats for these entrances as well. Does anyone have specific experience with this condition? Note that the terrace/patio is fenced so there is no entrance/egress from adjacent surfaces (paved or vegetated).

Thanks for your input. David
