I have two questions:
1) Can I utilize version 4.1 version of this credit instead of 4.0? It fits better to this project, because no signs are necessary as the no-smoking policy is communicated to occupants of the building and have in place provisions for enforcement.
2) Smoking is not allowed at all bot outside and inside the building. Is it accaptable that the only signs are on the enterance doors? There are no dedicated smoking areas outside, as smoking is not allowed confirming the no-smoking policy.
