Hazardous Chemical Clarification

The small project I'm working on will have a small janitors closet with a mop basin, as well as a stacked washer/dryer for rags and towels. We have a green housekeeping plan for the project, and the owner is committed to using all green, non toxic cleaning, laundry, and dish washing products for their facility. It is a Boys & Girls Club, and the health of the Club's members (children) is a big priority for the Club. So I would interpret the project as having NO spaces where hazardous chemicals or gases are present. How should I indicate this? There seems to be no options for a project with no hazardous chemicals present. I was thinking I would just briefly describe and reference the housekeeping plan (which will be submitted as an ID credit) in the "Special Circumstances" section. Is that appropriate? Has that strategy been used successfully in the past?
