Here are some links and handouts from today's class.

This pdf from NIOSH - National Institute for Occupational Safety and Health, has some great information about electrical safety as well as numerous case studies. We'll spend a good part of tonight's lecture discussing this document. A printed copy will be provided to you in class on 2/11.

I won't print this out, but it's worth a look.

Which is More Dangerous to the Human Body - AC or DC?

NOTE: I've used Home Depot links below, but there is no endorsement of Home Depot implied or otherwise. They are just convenient and I used the same vendor for consistency.

DO NOT PRINT THIS, IT IS A LONG DOCUMENT!!!!! You can register here to receive this directly from the publisher and see other related content they have available.

The above document is WAY more detailed than we'll cover in a course such as this, and we'll mention more about this in the chapter on Electrical Safety.
