how many of you did not use the mask that they recommended?
be honest!
i did not use a mask and found the vapors less powerful than Api guard thymol gel.. i do wear gloves when using MAQS but not with the Apiguard...
Masks are not required in Canada. I guess they just have better lungs that us USA'ers. To answer your question NO
anyone read Randy Olivers article in Sept ABJ on quick strips? He made a statement about how crazy the mask requirement for these is and even made the comment that the added expence might stop large operations from using them
