If I read your note correctly, I believe your tentative conclusion, below, is incorrect. The difference between Z136.1 and Z136.8 has nothing to do with wavelength.


Z136.1 is the broad standard on Laser Safety.


Z136.8 is specific to the use of lasers in Research, Development and Testing. Because it is "designed to be used in conjunction with" Z136.1, the relevant elements of laser safety that apply to all uses, and that are given in Z136.1, are not repeated in Z136.8.


So to effectively understand and apply Zq136.8, you need to also have access to Z136.1

The text describing Z136.8-2012 concludes with the statement: "The standard is designed to be used in conjunction with the ANSI Z136.1."  


ANSI's minimalist description of Z136.1 leads me to TENTATIVELY conclude that the difference between the two standards is the wavelength of the laser beam.  I recommend that you acquire clarification from an ANSI representative, and be certain that the lab design is suitable for the full range of anticipated wavelengths (from UV to visible, and perhaps infrared). If you need both standards, ANSI offers the two as a set.

Hello all,

We are in the processing of constructing a new lab building.  We will be using class IV and class III lasers.  Does anyone have standard regarding the outfitting of the lab (with safety curtains to divide the rooms)?  Where can I find the standard.
