One of the most essential parts of making a hazardous work environment safe is making sure the circuitry is good enough.  How can someone possibly make the environment safer for everyone to use?  While each environment is unique in its own way, this blog post will be a good starting point for you to get information on the workings of an intrinsically safe circuit.

What is Intrinsic Safety?

Intrinsic safety, as noted by a previous blog post of ours, “is a low-energy signaling technique that prevents explosions from occurring by ensuring that the energy transferred to a hazardous area is well below the energy required to initiate an explosion.” Everything that we sell on our website is intrinsically safe, which will ensure the safety of the environment where you are working.

Diving into Intrinsically Safe Circuits   

Some important points that need to be brought up are that the device, the barrier, and the wiring all are crucial to make the circuit work properly.  These intrinsically safe circuits, in theory, work well when conditions are normal.  When conditions are poor, then the circuit has measures in place to prevent it from becoming very destructive.

Approaching Intrinsically Safe Circuits

The way to approach the concept of intrinsically safe circuits is to make sure that the correct design procedures are taking place.  This comes from intrinsic safety in general, but it can apply to circuits. Electricity can be dangerous, and sparks can fly in the wrong places, so making sure Printed Circuit Boards aren’t faulty is just one way of making sure circuits are intrinsically safe.

There are methods and approaches to make the circuit intrinsically safe.  First, choosing the correct battery is the most important.  Second, be aware of where your connections can lead to, and make sure non-intrinsically safe equipment is kept out of reach.  Keeping the environment in mind is incredibly important as well.  Choosing the right protection for your equipment is also incredibly important.  What has just been stated are simply some of the very important methods and approaches to create an intrinsically safe circuit.


Be sure to check out the products that we have on our website, such as flashlights, headlamps, and cameras.  These are all made intrinsically safe so that the product can work in these very hazardous environments.  Even products such as cords and explosion-proof fans are available on our website for the purpose of making sure that the products are safe to use.

Some other products that we have on our website are also worth checking out, such as Explosion Proof Lighting and tablets. If you’re interested in reading more about intrinsically safe tablets, take a look at our blog post about them.

So What is the Overall Message and Next Steps?

This blog went over many key aspects of intrinsically safe circuits.   The wiring is essential, as these circuits are built to specifically handle dangerous environments.  It is necessary to make sure that the correct procedures are being followed when designing circuits. Appropriate adjustments must occur when necessary to make the circuits safe.  Please check out the products that I have listed in the products section of this post!  I guarantee you won’t be disappointed.
