EMF Field Guides: The Beginner’s Guide to

Common Office EMF Sources & Other Work Environment EMFs

In this field guide, we’re going to go over some of the common office EMF Sources and more unique work environment EMF sources that you may come across.

You likely won’t have thought of some of these before.

Let’s begin:

Common Office EMF Sources

In this section we go over some common, industrial workplace and larger office EMF sources. Please see our section on home office EMFs for more tech related entries.

With all our sections, we’ve included a recommended solution for most of these. Many of the recommendations are under the assumption that the sources can’t be changed, but it’s always worth speaking with your bosses or the heads of the companies to see if they’ll take some proactive steps (like hardwiring the internet).

Wi-Fi Routers

Wi-Fi Routers

We covered these in previous sections, but these are extremely common in offices now. Just be aware of where these are, as it’s not recommended to be right next to them for 40 hours a week.

Computers & Computer Peripherals

Computers & Computer Peripherals

We covered these in our chapter on EMFs in home offices, but these can put off a wide array of EMFs from RF to magnetic to electric fields. For a safer office environment, please see our section on low-EMF office products.

Electrical Wires & Surge Protectors

Electrical Wires & Surge Protectors

We went over this in the home office chapter. Basically, you want to move these away from where you sit at your desk as much as possible.


Fluorescent Lights

These can be responsible for elevated magnetic fields, but the field reduces quickly with distance.

Just make sure that you don’t have them right above you.

Section 02

Transformers, Electrical systems & Utility closets

These can be responsible for sizeable AC magnetic fields.

If you’re working regularly in an adjacent area, it’s worth surveying it with a gaussmeter (and an electric field meter).



These can lead to elevated AC magnetic fields in adjacent areas.

Like the above section, it’s a good idea to survey your office if nearby.

Copy Machines

Copy Machines

The concern here is elevated magnetic fields. If your job entails making lots of copies, try to stand back from the machine when doing so.

There obviously may be RF fields, too, from wi-fi or bluetooth functionality.

Industrial Furnaces & AC Units

Office Furnaces & AC Units

Due to their motors and heating elements, there may be some elevated magnetic fields. Figure out where these are located and survey the areas that you frequent.

Unique Occupational Tools

Unique Occupational Tools

This can be a wide array of things. For instance, if you’re a welder you’ll want to be aware of the magnetic fields produced from the torch that has elevated magnetic fields. If you make a lot of calls during the day and wear a bluetooth earpiece, you’ll want to be aware of the RF fields near your head.

Take note of the occupational tools you use and determine if there may be any issues with each.
