Calculating Laser System Hazards

Instructor-led Virtual Training - Course Overview

This highly requested course is now available to you from the comfort of your home as a live, web-based training option. Over the span of two and a half days, students will learn how the ANSI Z136.1 standard is used to quantify the hazard of a laser system. It will cover computing the Maximum Permissible Exposure (MPE) for various laser types, comparing actual laser exposure to the MPE, computing the Nominal Ocular Hazard Distance (NOHD), determining the Optical Density (OD) required to protect from a laser system, and it will provide a general overview on how lasers are classified.

Emphasis will be given to understanding how various tables are used to compute the MPE. Examples will be detailed and include discussions of the equations that are used to evaluate hazards, how they are used, and where they come from. Space is limited, so reserve your seat today!

In addition to the working knowledge you will gain, you will earn 1.5 BLS CM Points by the Board of Laser Safety upon completion of the course.

Learning Objectives: 

  • Identify what laser parameters are necessary to compute the MPE for various types of exposure.
  • Determine the MPE for direct viewing of laser light.
  • Determine the MPE for viewing diffuse reflections of laser light.
  • Compare actual exposure to the MPE to determine "hazard".
  • Determine the Nominal Ocular Hazard Distance for various laser systems and viewing conditions.
  • Determine the Optical Density required to protect from various laser systems.
  • Determine the classification of a laser system.

Anyone who needs to understand how the ANSI Z136.1 standard is applied to determine the hazard of a laser system. This course is designed for those who need to perform laser hazard calculations or understand hazard calculations performed by someone else. This course does not substitute a complete Laser Safety Officer (LSO) training. For a comprehensive laser safety officer training, see our LSO and LSO with Hazard Analysis training course options here:

LSO with Hazard Analysis Training

All attendees will receive a digital access to course notes and a certificate of attendance upon successful completion of both days. This course is worth 1.5 Board of Laser Safety CM points upon successful completion.
