Overview of Laser Control Measures

ANSI Z136.1-2014 "Safe Use of Lasers" requires the application of control measures to reduce the possibility of exposure to laser radiation above the MPE. The LSO has the authority to monitor and enforce the control of laser hazards. There are 3 types of controls – Engineering, Administrative (Procedural) and Personal Protective Equipment.  Engineering controls are [...]

Are Your Laser Signs Compliant?

When ANSI Z136.1 “Safe Use of Lasers” was revised in 2014, one of the most significant changes was laser sign design.  Over the past 20+ years I’ve visited many facilities ranging from universities to industrial plants and medical facilities.  I find more often than not laser signs are not compliant with ANSI.  So – here’s [...]
