I worked on this list until late last night:
This is a working document for our teaching labs. It is not a replacement for the SDS, but a way to give students direct links to PubChem entries with health and safety or toxicity information.
A couple of these reagents are a mixed bag, for example ligroin (petroleum ether) and hexanes, so I listed out the most common species found in each.
I would love some input from more experts on this. I have already shared the list with the student in question and also made it available to the entire class.
Thanks again to everyone for your help and support!

Thank you everyone for these excellent comments!
Emerging Consensus (Cross-Cutting Themes)- SDS literacy is essential but insufficient → must supplement with PubChem LCSS, curated lists, hazard assessments
- Chemical lists/inventories must be provided to make physician consultation meaningful.
- Disclosure is voluntary (Title IX, Pregnancy Discrimination Act).
- Accommodations are common: modified roles, alternative assignments, deferment with no penalty.
- Ventilation/containment is under-discussed but critical: odors = exposure (Jon ASU).
- Legal backbone: Johnson Controls (1991) → institutions must protect both mother and unborn, cannot exclude, cannot offload responsibility.
Again, thank you all so very much. This input is extremely valuable.
We have some work to do. Just 40 minutes south of our campus, Utah Valley University has 12 mini fume hoods in every O-chem lab. That allows every pair of students to handle reagents and materials fully in the hood.
Thank you all again!
- Bruce Van Scoy emphasized that SDS literacy is essential, but this is insufficient on its own and must be supplemented with resources such as PubChem LCSS, curated lists, and hazard assessments (Sammye).
- Tessa Stewart and Rose Rakers showed that chemical lists and inventories must be provided in order to make physician consultation meaningful.
- Debbie Decker reminded us that disclosure is voluntary, reinforced by Title IX and the Pregnancy Discrimination Act.
- Tricia Hahn, Sammye, and others highlighted that accommodations are common: modified roles, alternative assignments, or deferment with no penalty.
- Jon Klane noted that ventilation and containment are under-discussed but critical; if you can smell it, exposure is occurring.
- Catherine Situma shared Auburn University’s comprehensive reproductive health policy, which may serve as a strong model.
- Harry Elston pointed us toward ACS CCS legacy guidance, while Marta Guron recommended the Lane et al. (2022) article as a scholarly baseline.
- Jim Kaufman reminded us of the legal backbone from Johnson Controls (1991), which makes clear that institutions must protect both mother and unborn, -- cannot exclude, and cannot offload responsibility to a PCP.

This unfortunately is contrary to the US Supreme Court decision in the United Autoworkers vs Johnson Controls 1991.
The employer must protect both the mother and unborn child.
The employer must understand the reproductive hazards of their chemicals. They must train, inform and not hand it off to an employee's PCP (who may be totally clueless).
I had one related case that settled at 10 million. ... Jim

When I was a member of Farmingdale State's chemistry faculty, the college policy was to make available a list of all chemicals to any student if they requested it. The students were then informed that guidance in this matter should come from their physician.

Dear DCHAS Colleagues,
I'm a part time adjunct lab instructor at a community college. I would appreciate your advice on a situation in my organic chemistry teaching lab today.
One of my students confided last semester (in general chemistry II) that she has experienced multiple early pregnancy losses over the years and how heartbreaking that was for her. Now today, a brand new semester, in organic chemistry, she shared the joyful news that she is expecting and asked if there are concerns with her working with or handling today's lab materials.
I reached out to a nearby more experienced colleague just down the hall but received little direction beyond the idea that she should avoid handling chemicals directly and instead contribute through documentation and observations while her partner does the manipulations.
Today’s experiment was a simple extraction using naphthalene and benzoic acid, but the naphthalene odor became more noticeable as the first hour progressed even with good ventilation and fume hood use. Out of caution, I excused her from the lab after reviewing information that indicates naphthalene fumes can be problematic during pregnancy.
I would like to know from this group:
Do your institutions have written policies or guidelines for mothers-to-be in teaching labs?
Are there specific substances (like naphthalene or common solvents) you flag as higher-risk during pregnancy?
How do you balance protecting health while still supporting a student’s educational progress?
Given her personal history, I want to be proactive in safeguarding her well-being while keeping her on track academically. Any perspectives, examples, or resources would be very helpful.
