Safety Protection Measures - Panasonic LP-310 Operation Manual

Safety Protection Measures

This product falls into Class 4 laser (marking laser) and Class 2 laser (guide laser) based on the classifications of the Safety
of laser products (JIS C 6802) / FDA standards 21 CFR 1040.10 and 1040.11/IEC60825-1.
Perform the safety protection measure shown below before using the system.
For more detail instruction, refer to each of the standard.
1. Construction of interlock system
In order to prevent exposure to laser beam accidentally reflected from the laser marking object or from its
circumferential areas, place a protective enclosure so that it can enclose the area in the range of laser
radiation, and construct the interlock mechanism in the system.
Additionally, install the control part that is not to exposure to the laser beam. Refer to "Construction Sample of
Interlock System" (P.14).
•
For laser pumping is shut-off by interlock system, construct a laser re-pumping system by
manual operation for safety.
WARNING
2. Wearing protective goggles
For protection eyes of an operator, make it mandatory to wear goggles against laser beam in the laser
controlled area.
For this product, use the laser protective goggles or glasses which meet the following requirements.
•
The goggles or glasses that have Optical Density (OD) of more than 6 at wavelength 10600nm (10.6μm).
•
Through the goggles or glasses, the laser radiation indicator should be recognized.
•
ANSI Z136 and CE certified laser safety goggles or glasses
The protective goggles can momentarily protect the eyes against the scattered beam. Never look at the direct
beam or reflected beam even when the goggles are used.
3. Protective enclosure
In order to prevent exposure to laser beam accidentally reflected from the laser marking object or from its
circumferential areas, place a protective enclosure so that it can enclose the area in the range of laser
radiation.
Construct the enclosure with proper reflectance, durability and thermal resistance materials that does not
transmit a wavelength of 10600 nm (10.6 μm).
Recommended materials for the enclosure: metals such as iron, aluminum, stainless steel, or acrylic resins.
For acrylic plate, its thickness should be more than 3 mm and it is recommended to use the plate that has a
color to reduce the secondary radiation beam such as spark during the lasing.
Design the enclosure not to leak the laser beam from the joint parts.

4. Key control
In order to avoid the operation of the system by the person without authorizatio and allowance, the laser
safety manager must remove key and keep it when not in use.
•
It is obligated by IEC/FDA/JIS that laser products shall incorporate a key-actuated master
control. Actuation of Our laser marker is basically controlled by the key switch located on the
front of the power supply box. However, in considering situations when the laser marker is
operating as a part of a larger system, the laser marker turns on if the key swith is already in ON
WARNING position, and power is supplied.
•
In this case, be sure that the external system controls the operation of the laser marker with a
key-actuated master control.
