Hi all,

I'm working on an academic facility with a multi-faith space within it that will occassionally be used for Indigenous smudging ceremonies (burning of herbs and grasses, including tobacco sometimes). Does anyone have any experience with this and the ETS prerequisite? 

Would there be an exception based on the frequency and non-nicotine containing smoke, or would we have to treat the space as a "designated smoking area" or similar to a residential suite with smoke seals to avoid cross-contamination? Any precedents from other similar uses such as incense burning?

Thanks in advance.
