Colleagues,

At Yale, we do not allow the use of a face shield in a lab without a mask or a face covering, but that is not my question.

Now, as in the past, we DO use face shields for laboratory PPE�when it is appropriate to protect the face and eyes.

I understand that some plastics are more flammable than others. Some labs use pyrophorics, and other have open flames.

What information is available about the flammability of the plastics used in face shields? Are there some plastics that I should avoid? I hope the wisdom of this group can help me find answers.

What about plastic goggles and safety glasses? Are they flammable? Are they tested for flammability?

Thank you!!
