FYI. We did silane flame testing of PPE in 2010 before the startup of the silane manufacturing process in Midland, MI. A polycarbonate faceshield from MSA held up extremely well to a 1-2 sec burst from a silane flame. After the test we were able to wipe it clean and it looked new.

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!!
