What does LASER stand for? - correct answer Light Amplification by the Stimulated
Emission of Radiation
What kind of light do Lasers Emit? - correct answer A Single wavelength of Coherent
Light
Why are laser lights more of a hazard then regular lights? - correct answer All of the
energy is directed in one direction, more concentrated making it more harmful.
What is the most hazardous forms of laser exposure? - correct answer Intrabeam
viewing, Reflection-Specular
What kind of burns can the laser produce on skin? - correct answer 1st, 2nd and 3rd
degree
At what UV length does Photokeratitis occur? - correct answer 100-315 nm
What provides reasonable and adequate guidance for safe use of lasers? - correct
answer ANSI Standard
Class I Lasers - correct answer Exempt from most laser safety rules, incapable of
producing damaging radiation levels, must be labeled
Class II Lasers - correct answer Low Power, 400-700nm , can cause damage from
continuous direct viewing
Class 4 Lasers - correct answer visible or invisible beams, immediate damage to eyes
and skin, may pose fire hazard
Maximum Permissible Exposure (MPE) - correct answer Level of laser exposure to
which a person may be exposed w/out adverse effects
Nominal Hazard Zone (NMZ) - correct answer space within which level of direct,
reflected, or scattered light exceeds MPE level
Electrical Hazards - correct answer Most Significant Hazard in the lab
Laser Generated Air Contaminates (LGAC) - correct answer toxics, corrosives or
flammables on interaction with target materials
Alignment - correct answer Largest cause of laser accidents
Danger Sign - correct answer Tells you type of laser and or wavelength, pulse duration
and maximum output
