Our LABORATORY REGULATIONS require: APPROPRIATE CLOTHING: Lab Coats, Long Pants and Closed Shoes are required. Choose sturdy shoes that cover the whole foot and protect from spills and broken glass. Wear a knee-length, long sleeve lab coat closed to protect skin & clothing. Coat sleeves must cover arms & shirts. Wear long pants (or equivalent) to protect from spills & splash. Avoid loose or synthetic clothing; remove loose jewelry; secure hair and clothing away from flames, equipment, and chemical contamination.
In our FAQs page: Skinny jeans are not recommended for lab work because a splash that is absorbed into the fabric will reach your skin faster than it would with looser pants. We recommend pants with some space between you and the fabric (such as your cotton sweatpants). In an emergency, you'll have more time to react.
In my Clothing for CHEM Lab email I send to all students (definitely falls into "interpretation"):
LONG PANTS (or their equivalent) are required to protect the legs and ankles from splash contamination.
¥ Leggings are not pants and are NOT PERMITTED. Tight pants (skinny jeans) do not provide protection and may be interpreted as "leggings" for the purposes of this rule.
¥ Make sure you have at least one pair of pants that covers your ankles and provides substantial air space between the fabric and your skin - especially below the knee.
¥ Other questions about what is "equivalent" should be referred to the Safety Coordinator (me).

Do you permit your students to wear leggings/jeggings in your academic chemistry labs?
If not, have you included a section on this in your safety rules?
Would you be willing to share the wording in your safety rules with me?
I chair the departmental safety committee and I plan to include this topic as an agenda item for the February meeting.
As always, thank you for your assistance.
