Barbara,


Per our discussion yesterday, I must "piggy-back" on Jim's last sentence (aka, statement) to emphasize by adding in a few words,

"PPE is always the last resort for hazard control and when necessary should include only the appropriate devices MATCHED TO THE INTENDED APPLICATION regardless of cost."

As a corollary to that statement we cannot overemphasize the importance of training and fitting / fit-testing to help insure that the employees and/or students can do their assigned task, experiment or job while (comfortably) wearing the equipment.  

Marrying several type of PPE to an individual is like solving a jig-saw puzzle; all of the pieces must fit!

On another note, some protective safety eyewear manufacturers have available several type of safety goggles depending upon the application and exposure to particulate and gaseous matter and radiation: 


Do check with your preferred vendor or manufacturer's representatives to help you with your need.

Be Safe, Secure & Sound in Judgement, Vigilant as Always and Stay Well!

All My Best,

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.

DCHAS Colleagues:

Has anyone found a workable solution to the problem with face mask+goggles= fogging in student chemistry labs?

Thanks for your assistance.
