Final quiz on Laser Safety

You're given a laser operating at the wavelength of 633 [nm] with a power of 12 [mW]. Should you wear goggles?

Yes, because it's a class 3B laser

Yes, because one must always wear goggles

No, because it's a class 3R laser

No, because it's a class 3B laser

Your goggles have an O.D. Rating of 3.0 at 800 - 900 nm range of wavelengths. Can you use it to safely operate a laser at that wavelength with power of 2 [W] ?

Yes, the power will be reduced to 200 mW which is acceptable

Yes, the power will be reduced to 2 mW, which is acceptable

No, the power will be reduced only to 20 mW

No, the power will not be reduced down to a sufficiently low value

A new graduate student approached you and told you it's ok to use a DYE laser withoug checking the compressed gas vessels and/or chemicals for being in a proper condition. Would you agree with that?

Yes, because graduate students are smart

No, because I don't trust new students

No, the DYE lasers present a serious danger, including what the student proposed to ignore

Yes, compressed gases are not a legitimate hazard.

When entering the protected area of the laboratory, it is imperative to do the following (check all that apply):

Make sure you don't wear anything that can reflect the laser light

Make sure you wear appropriate clothing covering your hair and body

Make sure you wear goggles if required by the laser to be operated

Make sure nobody's watching

Make sure you have a good mood

Make sure your haircut looks cool

The laser interlock system in our lab only shows if the dangerous lasers are on or off. In that case, it is required to do the following:

Use appropriate safety goggles

Use engineering controls

Allow only qualified people inside the working area

Enter the room shouting that you're coming in

Enter the room with eyes closed

Hope for the best and come in unprepared
