Laser Classification

General
The following chapters provide instructions and training information about laser safety
according to international standard IEC 60825-1 (2014-05) and technical report IEC TR
60825-14 (2004-02). The information enables the person responsible for the product
and the person who actually uses the equipment, to anticipate and avoid operational
hazards.

According to IEC TR 60825-14 (2004-02), products classified as laser class 1,
class 2 and class 3R do not require:
• laser safety officer involvement,
• protective clothes and eyewear,
• special warning signs in the laser working area
if used and operated as defined in this User Manual due to the low eye hazard
level.

National laws and local regulations could impose more stringent instructions
for the safe use of lasers than IEC 60825-1 (2014-05) and IEC TR 60825-14
(2004-02).

DISTO

The DISTO module built into the product produces a visible red laser beam which
emerges from the window at the top of the product.
The laser product described in this section is classified as laser class 2 in accordance
with:
• IEC 60825-1 (2014-05): "Safety of laser products"
These products are safe for momentary exposures but can be hazardous for deliberate
staring into the beam. The beam may cause dazzle, flash-blindness and after-images,
particularly under low ambient light conditions.

From a safety perspective, class 2 laser products are not inherently safe for the eyes.
Precautions:
1) Avoid staring into the beam or viewing it through optical instruments.
2) Avoid pointing the beam at other people or at animals.
