My work has a laser device.
His rank is Class 1.
It has a removable shield, You can see in the example video:


Inside the device is a Class 3A laser.
When the shield is removed. Did the laser become Class 3A?
Or because the laser turns into lines it becomes weaker?

A laser regulatory authority has reviewed the device and decided/determined it is Class 1 device as a while device. If it says class 3a inside then that is what the laser diode by itself is, as opposed to a complete device operated in the manner it is supposed to be operated.
The laser manufacturer and the laser laws, rules, and regulations people in your Country decide what the device classification is. Other than minor differences and sub-classifications, classifications are pretty much universal by agreement between the Countries about laser classifications.

You already have 21 posts all centered around eye safety and a bar code scanner.
Look back through all your threads --pretty much exhausts anything anyone can say about it on LPF especially since you have never provided any imformation on the make and model of it to verify or find anything about it nor what Country you are in a regulations differ a bit Country to Country

Maybe a better idea to email the maker of the scanner and ask them.
You don't identify the type and maker of the bar code scanner ---maybe look and find out, then email them.

Nobody on LPF is a commercial bar code scanner specialist.
Safe to say laser devices are all regulated and given classifications for safe public use in tens of thousands shops all over the world.
I have never seen or heard of anyone working a bar code scanner wearing laser safety glasses so....

Best idea would be to contact the manufacturer and ask any questions about any concerns you have.

Hope that helps

Here is the booklet with the warnings and instructions and the model of the device:

From what I understand from you Class 3A a laser that is alone and not inside the device?
This is according to the European standard.

No you have it wrong---It is a Class 1 or 2a device --the lasers inside are Class3a

It is a Class 1 laser product. The system uses two embeded Class 3a lasers------product and lasers are different things and classifications

Says very clearly on page 12 of the manual:
"Laser safety requirements are based on IEC Standard Publication 60825-1(2007) and CDRH 21CFR, Chapter 1, Subchapter J and (CDRH) LaserProduct Performance Standard, User information [1040.10(h)1]:• User Maintenance. No user maintenance of the laser system otherthan cleaning of the scan windows is required.• Radiant Energy. The scanner is an IEC Class 1 and CDRH IIa lase rproduct. The system uses two embedded Class 3A Visible LaserDiodes (VLDs) operating at 650.0 nm, in an opto-mechanical scanner, resulting in less than 3.1μW radiated power as observedthrough a 7mm aperture averaged over 10 seconds. Maximum emit-ted output power at the lower (sealed) window is 880μW, pulseduration is 89 μS. No attempt should be made by the user toremove the protective housing of the scanner/scale.• Laser Light Viewing. The horizontal and vertical scan windows arethe only apertures through which laser light may be observed in this product.
Exposure to the light emitted from the scan windows has been shown not to be harmful.
The safety record of bar code scanning is perfect after millions of hours of use worldwide. This safe and efficient use of laser technology has gained wide acceptance in industries throughout the world "


The laser safety data in at top of page 16--It complies with all standards USA for a Class 11a device and Europe as a Class 1 .

Suggest you contact the manufacturer with any questions or concerns you have about it or difficulty comprehending what it is.

If you imagine you have vision issues or concerns you should go see a qualified eye MD Ophthalmologist and have him examine and test your eyes/vision and tell you if you have a discernible vision problem from whatever cause.

There are tens of thousands of bar code scanners used millions of time daily all around the world with no negative effect to eyesight for years.
