Hi Chandra,
I spoke to one of our IHs and she shared the following:
“We do not have a guidance document for formaldehyde/formalin exposure but as an institution we conduct regular sampling for formaldehyde in our anatomy labs that perform embalming for the donor bodies and we use a combination of engineering,
administrative, and PPE controls. This includes but is not limited to the following:
- Downdraft table
- Using push/pull ventilation system
- Only having one embalmer do the embalming procedure in a room with engineering controls mentioned above.
- Embalming of no more than one donor body by the same embalmer within the same workday.
- Annual medical evaluation and fit test and provision of half face respirator with formaldehyde/OV cartridge.
We are in the process of doing sampling for the dissection lab. Depending on the sampling results we will follow a similar approach with control measures:
- Use of dissection tables
- Modification to ventilation system depending on the results
- Limiting the number of researchers doing dissection in a room
- Provision of respirator as an added precaution”
Let me know if you have any questions or would like to discuss further and I can put you in touch.

Hello Safety world,
I am reaching out to gather insight on how your institutions manage formaldehyde/formalin exposure in teaching laboratory settings, specifically anatomy or brain dissection labs.
Case Example: A teaching lab conducts brain dissections using specimens preserved
in approximately 10% formalin.
Do you have any institutional policies or guidance on managing exposures in this type of setting?
-Chandra
