Dear all,
I recently started my new position as a instructional support technician at my local university.
I am also supposed to manage the graduate laboratory. This is where I encountered a room with a muffle furnace that just vents into the room. It is set to 550 Deg. Celsius and used to ash plant tissues and food samples.
It is my understanding that those furnaces are supposed to have a separate ventilation or should at least be located inside of a fume hood (particulates, smoke, carbon monoxide ...).
Does anyone have a specific reference that describes the issue (standard, regulation, case study...)?
Thank you very much!
Best Regards,
Stella Sommer
