I can share an incident from my own research laboratory which highlights an issue for hearing impaired researchers working with gasses - they cannot hear flowing gas.
My student pressurized a reactor with carbon monoxide and after closing the reactor valve he pulled off the fill hose and let it hang next to the large tank secured outside the hood. He failed to close the valve on the carbon monoxide tank, which should have been done before removing the fill hose. I walked into the lab sometime later and while speaking with the student said "Mike, what's that hissing noise?" Of course he replied "What noise?" I immediately looked around and saw that the hose on the tank regulator was blowing carbon monoxide into the lab, so I quickly closed the tank valve and we immediately left the lab.
There were multiple issues here, but the student's hearing impairment prevented him from hearing the flowing gas.

Hi
Here is the link for the American Chemical Society's Chemists with Disabilities; with a lot of great resources. Hope this helps!

Hi,
I am checking in to see if any of you all might be willing to share experiences and/or policies and precedents for a deaf or hearing impaired teaching assistant working in Chemistry lab instruction.
Any and all contributions will be so appreciated,
Thanks,
