In construction and industry, some potential hazards visibly manifest, such as the risk of falls from heights. Others are more hidden. A confined space may not look dangerous, but workers perish each year because someone assumed the air inside was safe to breathe when testing would have revealed that is wasn’t.

With technology incorporated in nearly every aspect of our lives, you’ve probably wondered more than once whether someone was watching your every move. 

If your facility has confined spaces on site, it is critically important that you evaluate those spaces to determine if you need to have a permit-required confined space program. 

Broadly speaking, a confined space is an area that is large enough for a worker to enter and do work, but that is difficult to get in and out of easily, and not designed or intended for regular occupancy.

IEEE, the Institute of Electrical and Electronics Engineers, recently produced a paper1 reviewing 100 years of research on shock and arc injuries. Going back, the first recognized hazard to workers was the shock hazard.

We have all read the articles or posts on the questions regarding confined spaces such as “What is a confined space?” or “What makes your confined space permit required?” You might have even been asked “How do you re-classify a permit-required confined space?” or one of my favorites, “When do I need a rescue team at my confined space?” Let’s break it all down.
