Laser Safety Exam Questions and
Answers
How does a laser safety program help to protect you from laser-related incidents and
accidents? - Correct Answers -Prevent laser incidents and accidents
What is a possible result when a laser beam penetrates a surface? - Correct Answers -
The material can absorb the light, resulting in thermal interaction
The material can reflect the light, redirecting it from its intended source
The material can reflect the light, scattering it in different directions
All of the above
True or False? Laser light is like a flashlight beam in that it spreads out widely, making it
safe to look at briefly from a distance. - Correct Answers –False
What does a laser's emission indicator communicate to you? - Correct Answers -The
laser is on
Which of the following engineering controls should the lab or maker space have in
place? - Correct Answers -Protected area for donning eyewear
Non-reflective, non-combustible barriers and curtains
Interlocked exit door
All of the above
What is the most important reason to keep the entryway door to a Laser Controlled Area
closed at all times? - Correct Answers -It prevents accidental exposure to laser radiation
True or false: You may operate a Class 3B or 4 laser if you are working under the direct
supervision of someone who is trained and approved for that laser. - Correct Answers -
True
You are working alongside a colleague using a tunable laser. They adjust the laser's
wavelength but keep wearing the same safety glasses. As a responsible lab mate, what
should you IMMEDIATELY do? - Correct Answers -Remind them that they may need to
switch safety glasses
rue or false: Non-beam hazards include ultraviolet radiation. - Correct Answers -TRUE
