You will be unlikely to meet any of the code requirements for fire rating, spill protection, sweeping the area, or required containment. Generally a really bad idea.

Hi Everyone,


Our college is discussing returning our labs (currently virtual/at-home) to campus this Summer. We're currently teaching labs in portable trailers while our new science building gets constructed and it was suggested that we just open the doors to the outdoors and use fans to bring in outside air to increase ventilation. Is there anything we should be wary of in terms of this backfiring on us? Most of the gen chem labs don't use the fume hoods very much but our organic labs do use them quite often and I worry that open doors might have some unintended effects on fume hood airflow.


I've suggested that we take advantage of the college's sudden interest in getting us back on campus to bring an expert in to evaluate the situation. Any recommendations on what qualifications we should recommend to the higher-ups?
