These policies apply to sealed sources as well as to open isotopes regardless of physical or chemical form. Permit Holders or their designees shall obtain approval from the EHSD before placing an order for radioactive materials.

Lasers present many safety threats, but the most common threat is damage to the eyes.
Many lasers emit invisible ultraviolet or infrared radiation.
Laser devices require engineering controls to ensure safety. All Class 3 and 4 lasers require a combination of protective housing, area warning signs or remote firing capabilities. Be very careful when working with hand-held laser pointers. Do not allow children access to pointers. Wear protective clothing such as eyewear and skin protection as appropriate.
