Laser Safety
Section I: Introduction to
Lasers, like arc welders, are a source of intense light that require certain precautions to insure a
safe, comfortable, compliant, working environment. This is especially true since the laser
included in this marking equipment operates in the infrared (invisible) portion of the light
spectrum. The enclosure surrounding the marking area is designed to prevent human exposure
to the light emitted by the laser. The following information is the procedures taken to design a
safe, efficient environment for laser marking equipment.
Laser products are categorized into one of four classes based upon the power of the laser light
that is accessible to any person during normal operation. These classes range from Class 1, the
lowest class requiring no additional safeguards other than those provided by the manufacturer,
to Class 4, the highest class that requires additional operator and working environment
safeguards for safe operation.
Class 1 laser marking systems include enclosures integral to the workstation that are
constructed to prevent human access to the laser beam. Class 1 systems are safe in all
working environments; they are installed and operated the same as any other industrial
machine tool. Class 1 laser systems do not require the use of any special laser safety
equipment by operators or bystanders during their normal operation.
Class 4 laser marking systems do not incorporate protective enclosures. Extra precautions are
required with this type.
The laser marking system designed by InfoSight Corporation for the marking of tags complies
with Class 1 during normal use because of the numerous interlocks provided (detailed in
section II).
The Laser during Service and/or alignment is a Class 4. The service is done by a
Qualified
Laser Service/Safety Technician
! Because of the Class 4 classification, InfoSight will provide
such a person to be available to the end user of this marker.
The Power output of the laser used is 25 or 50 watts. It is a C02 infrared (invisible) laser with a
wavelength of 10.57 to 10.63 microns. The Radiant energy and the wavelength are less than
Class 1 requirements during normal operation.
