Q: We are a steel erection company and, for the last few years, we have been using only fiberglass extension and step ladders, but we have a few aluminum ladders in storage in our shop. Is there a rule regarding the use of aluminum ladders? I almost never see them used on job sites any more.

Radiofrequency (RF) radiation, a type of non-ionizing radiation, refers to energy that transmits wireless information with frequencies from three kilohertz (kHz) to 300 megahertz (MHz).
RF energy is essential for telecommunications services such as radio and television broadcasts, cellphones, microwave point-to-point links, and satellite communications.
Low-level RF radiation is not considered hazardous. However, at the levels produced by telecommunication equipment, it can pose a health risk for workers.
