 A WPP reaction module consists of a reaction chamber and vessel holder.
 By modifying chamber height and adjusting holder geometry, one can produce modules compatible with reaction vessels of various types and sizes.

 \section{Safety}
 
 WPP reactors utilize high-intensity light emitting diodes (LED) that can cause eye damage if proper safety precautions are not observed.
-Light-filtering safety glasses should be worn whenever a WPP apparatus photon source is powered.
-Care must be taken to use safety glasses protective against the specific emission wavelengths of the photon source.
+
+A light-blocking shield should be utilized whenever operating a WPP apparatus. 
+Care must be taken to ensure the light-blocking shield employed adequately blocks light emitted by a WPP photon source from directly reaching a user.

+A 3D printable light-blocking cover module for WPP devices is provided in the 'photoreactor-light-shield' subdirectory of the project repository.
+The WPP light shield prevents direct exposure of users to light emitted by WPP photon sources. 
+We recommend printing the WPP light shield using black filament is recommended to reduce light bounce (Figure 24).

+Use of light-filtering safety glasses alongside a light-blocking shield can provide additional protection from high-intensity light.
