What Class is a CO2 Laser? Understanding Class 4 Laser Safety

What class is a CO2 laser?

WarningAlways consult your on-site Laser Safety Officer (LSO) for specific guidance. Required optical density (OD) and laser safety personal protective equipment (PPE) are determined based on worst-case scenarios and require professional judgment. All laser safety equipment provided is intended for diffused beam viewing only.
CO2 lasers are classified as Class 4 lasers.
 
Laser classification is based on the potential for harm that a laser can cause to the eyes and skin, with
 
Class 4 being the highest and most hazardous classification

Class 4 lasers have the following characteristics:

1. They can cause severe eye injuries, including permanent blindness, if directly or indirectly viewed without appropriate eye protection.

2. They can cause skin burns if the beam comes into contact with the skin.

3. They can present a fire hazard due to the high power output.

As a result of their high power and potential for harm, Class 4 lasers require strict safety measures and precautions when used. These safety measures include the use of laser safety glasses or goggles with the appropriate Optical Density (OD) for the laser wavelength and proper training for personnel operating the laser.

It is essential to follow ANSI safety guidelines and manufacturer's recommendations when working with Class 4 CO2 lasers to prevent accidents and protect against the potential hazards associated with these powerful lasers.
