8.2.1 Class 1 Laser Product Cards
Figure 8-1 Class 1 Laser Product Label
Class 1 lasers are products whose irradiance does not exceed the Maximum Permissible Exposure (MPE)
value. Therefore, for Class 1 laser products the output power is below the level at which it is believed
eye damage will occur. Exposure to the beam of a Class 1 laser will not result in eye injury and can
therefore be considered safe. However, some Class 1 laser products might contain laser systems of a
higher Class but there are adequate engineering control measures to ensure that access to the beam is not
reasonably likely. Anyone who dismantles a Class 1 laser product that contains a higher Class laser
system is potentially at risk of exposure to a hazardous laser beam
8.2.1.2 Hazard Level 1 Label
The Hazard Level 1 label is shown in Figure 8-2.
Figure 8-2 Hazard Level Label
The Hazard Level label warns users against exposure to laser radiation of Class 1 limits calculated in
accordance with IEC60825-1 Ed.1.2.
8.2.1.3 Laser Source Connector Label
The Laser Source Connector label is shown in Figure 8-3.
