Which of the following is an example of a Potentially Hazardous Emitter?

• A. Short-duration emitters
• B. Inaccessible emitters
• C. Ground-level hazard emitters
• D. Climbing hazard emitters

Answer: (C)

The idea is that where an emitter is located largely determines who it can affect. Ground-level hazard emitters sit right where people are most likely to be—at the level of foot traffic—so exposure to hazardous energy (radiation, heat, chemicals, etc.) is more probable during normal activities. That immediacy of potential exposure makes them a clear example of a potentially hazardous emitter. Short-duration emitters can still be dangerous, but a brief exposure is less likely to create a sustained risk; inaccessible emitters reduce risk because access is restricted; climbing hazard emitters pose concerns mainly for workers at height, not the general ground-level population. So the ground-level location best illustrates a potentially hazardous emitter.
