When you have a question about process automation that needs a short answer, let us know with #WishIknew and @Visaya! We’ll reply with a #WishIknew post. It’ll give a quick explanation, then some related articles, videos, or reviews if you want to know more.

Wish I knew what intrinsically safe tools are!

This question is fundamental, but to give context to the answer, we need to know the basic concept of intrinsic safety. Then we can chat about intrinsically safe tools and their applications.

When you work in hazardous areas, you need to follow specific procedures to install devices or even bring devices to the field. And by hazardous area we mean places with high risk of explosion from the presence of flammable gases, vapors, liquids, or dust.

These areas have rigid classifications for the conditions and materials present. With these classifications, we can choose the right device, material, and procedure for working in these areas without exploding. You have different classes and zones, but we’ll have to save that for another article.

And that brings us back to intrinsic safety. It means you can work in a hazardous area with reduced current and voltage to avoid ignition. And of course, you have other methods such as explosion proofing.

So intrinsically safe tools means tools built to reduce risk of ignition. For instance, I can highlight tools such as intrinsically safe mA calibrators, multimeters, pressure calibrators, and so on.
