Barbara,There are face shields available that include a small, battery powered, fan that keeps the face shield from foggy. This type of face shield also provides far better protection than cheaper options. These shields are typically equipped with chin covering protecting against splash from all directions.Goggles typically have vents to mitigate fogging. However, that is another subject. If the task has such a high risk for eye damage that goggles are necessary then why include holes in the sides or top of those goggles?For high risk eye exposure I require employees to wear both safety glasses and a face.Over the past 40 years I have personally worn and observed employees wearing all manner of face and eye protection.Most fogging of safety glasses is a result of dirty glasses and moist exhaled air traveling up and under the glasses fogging the inside. Glasses that fit snuggly against the cheeks help reduce the effects of this moist breath. The outside of the lenses rarely if ever fog.PPE is always the last resort for hazard control and when necessary should include only the appropriate devices regardless of the cost.Jim Keating--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchasOn Wed, Sep 2, 2020, 11:13 AM Barbara Foster <bfoster**At_Symbol_Here**wvu.edu> wrote:--- For more information about the DCHAS-L e-mail list, contact the Divisional membership chair at membership**At_Symbol_Here**dchas.org Follow us on Twitter **At_Symbol_Here**acsdchas
Has anyone found a workable solution to the problem with face mask+goggles= fogging in student chemistry labs?
Thanks for your assistance.
