Subject: Re: ANSI Z87.1 Standard Confusion
I received a clarification (for the message below)  .  The  author wrote (in 
part) ...
<< Teachers do not know the (ANSI Z87.1) standard refers to impact  only. 
What is difficult to understand about this? >> 
What is difficult to understand is why some might believe that this is  true. 
 It is simply not true.  The ANSI Z87.1 standard is NOT "simply  an impact 
standard" and it does NOT "refer(s) to impact only."  
Hopefully, no one else on the DCHAS discussion list is laboring under the  
same misconception.  

The ANSI Z87.1 is a general eye and face protection standard that  deals with 
five different types of hazards: Impact, dust, chemical, heat, and  optical 
radiation. It provides specifications for several different types of  
protective devices and indicates which type of device is appropriate which type  of 
Furthermore, I believe that it is not primarily ANSI's fault (as the author  
suggested to me) that school science teachers do not understand which type of  
eye protector to use.  In my opinion, the fault here lies primarily  with 
employers not doing what they are supposed to do under the OSHA  29CRF1910.132 
and .133 standards: identify the hazards in the workplace, decide  what 
protective equipment should be used, train employees, ensure that the  devices are 
available and used, and more.  
Others contributing to science teacher confusion include (but are not  
limited to) well-intentioned folks who teach them this and other kinds of  
misinformation; professional organizations that publish improper,  misleading, and 
confusing photos; and manufacturers/vendors who provide  incomplete, incorrect, 
and misleading product/safety  information.

Happy Holidays, ... Jim

"They  simply tell me that the  science catalog indicated the safety glasses 
met the  ANSI Z87.1  standard-not knowing it is an impact standard only."

I'm not sure I  understood what you meant here.  ...  Jim
