Before you buy: what your employer must also provide
This course does not train anyone to service, align or bypass interlocks on lasers. Your employer must provide training specific to its lasers, issue eyewear matched to each laser's wavelength and optical density, and authorize anyone who works on Class 3B or Class 4 systems.

About this course
Laser markers, UV depaneling systems, laser soldering cells, fiber laser engravers and sheet metal cutters are now everyday equipment in electronics assembly and metal fabrication. Most are sold as enclosed Class 1 products, yet many contain a Class 4 laser powerful enough to cause permanent eye injury in a fraction of a second, often with an invisible beam and no pain. This course explains the hazard and the controls that keep you safe.
You will learn how wavelength decides whether the retina, cornea or skin is at risk, why reflections from shiny metal and solder matter, and what the maximum permissible exposure and nominal hazard zone are. You will learn the seven hazard classes used by ANSI Z136.1-2022, how they relate to IEC 60825-1, how FDA classification under 21 CFR 1040.10 and Laser Notice 56 fit in, how to read laser labels, and why an enclosed Class 1 machine becomes a Class 4 hazard when a panel is removed or an interlock is defeated. You will learn the role of the Laser Safety Officer, the engineering and administrative controls in a laser program, and how to check laser eyewear by wavelength and optical density. The final module covers laser generated air contaminants, high-voltage and fire hazards, what to do after a suspected exposure and your day-to-day responsibilities.
OSHA has no specific laser standard for general industry. It enforces laser safety through the General Duty Clause and the PPE standards in 29 CFR 1910.132 and 1910.133, and refers employers to ANSI Z136.1. State-plan states may add requirements.
What this course does not do. It is awareness training for people who work near lasers or operate enclosed Class 1 laser systems. It does not train or authorize anyone to service, align, repair or open laser equipment, to work on interlocks, or to operate open-beam Class 3B or Class 4 lasers. Your employer must add site-specific and equipment-specific training: your lasers, their classes and wavelengths, your controlled areas, your eyewear, your procedures and your Laser Safety Officer.
The course closes with a 10-question examination drawn from a bank of 20. On passing you receive a PlanetISO Certificate of Completion for the instruction delivered online, with lifetime access to the course. The certificate does not expire.
What you will be able to do
- Explain how laser wavelength determines whether the retina, cornea, lens or skin is at risk, and why invisible beams are especially dangerous.
- Describe the maximum permissible exposure and the nominal hazard zone and how they define where protection is needed.
- Identify the seven ANSI Z136.1-2022 hazard classes, relate them to FDA and IEC labeling, and read laser warning, aperture and housing labels.
- Explain why an enclosed Class 1 laser system can expose a Class 4 hazard during service or when interlocks are defeated.
- Describe how OSHA addresses laser hazards in general industry and the role of the Laser Safety Officer.
- Select and inspect laser eyewear by wavelength and optical density.
- Recognize laser generated air contaminants, electrical and fire hazards, and respond correctly to a suspected exposure.
Course outline
- 1
How lasers injure eyes and skin
What makes laser light different, how wavelength decides which part of the eye or skin is hurt, why invisible beams are the most dangerous, direct and reflected exposure, and the exposure limit and hazard zone concepts.

Laser classes, labels and enclosed systems
The seven hazard classes used by ANSI Z136.1-2022 and how they relate to IEC 60825-1, how FDA classification and Laser Notice 56 fit in, reading laser labels, and why an enclosed Class 1 marker can hide a Class 4 laser.
