Bitmain's Antminer A3 may be emitting HCHO (Formaldehyde)

This video has just been published and is going around which shows HCHO levels are dangerously high coming straight from the Antminer A3. https://www.youtube.com/watch?v=k4SlUW1LWoU

0.612 mg/m3 is A LOT! The recommended ambient levels depend on the organism that makes the guidelines, but the WHO, for example, recommends no more than 0.023 for working environments (https://www.cdc.gov/nceh/ehhe/trailerstudy/pdfs/08_118152_Compendium%20for%20States.pdf)

For those who aren't familiar with what HCHO does cancer.gov states the short-term effects are "individuals may experience adverse effects such as watery eyes; burning sensations in the eyes, nose, and throat; coughing; wheezing; nausea; and skin irritation" along with The International Agency for Research on Cancer (IARC) classifies formaldehyde as a human carcinogen.

What's everyone's thoughts and might it be possible that the D3/S9/L3 could have the same problem?
