and application specific safety procedures: T
3. Which of the following is this curriculum NOT relevant for?: Industrial laser processes
4. Which of the following is NOT part of the Health Care Laser System (HCLS) apparatus?:
Stainless steel tools
5. Medical lasers typically operate between which wavelengths?: 180-1000 nm
6. True or False? This course also applies to anyone who might install, calibrate, operate,
maintain, or service the
HCLS.: T
7. Whose responsibility is it to establish a laser safety program at their facility and ensure
that All employees who might be exposed to medical laser radiation are properly trained?: a.
The employer
8. True or False? Laser safety control measures are dependent on the laser hazard
classification, which is based on the laser radiation output level and its capability of
damaging skin and eyes. It is also dependent on how much of that radiation is accessible
during the operation of the laser system: T
9. Which of the following systems are not capable of damaging the human body or eyes?:
Class 1
10. . Which of the following systems have laser radiation that is applied in direct
contract with a specified target other than ocular tissue, such as skin, acne, hair, or
wrinkles?: Class 1C
11. Which of the following systems are not capable of damaging the human body
or eyes unless viewed with a collecting optic?: Class 1M
12. True or False? Class 2 systems are safe in that the human eye's natural reflex to
avert keeps it from absorbing too much radiation before it is damaged.: True
13. Class 2M systems are safe in the same way that Class 2 systems are, with the aversion
response of the human eye, but can be potentially dangerous under which of the following
circumstances?: b. When viewed with a collecting optic.
14. Which of the following systems can be potentially hazardous if the beam is
viewed directly or is viewed reflecting off of a specular surface?: a. Class 3R
