confined space examples

Since it is very critical for you to know a work is defined as confined space work or not, so I think it will be very valuable if I can show you as many confined space examples as I can.

If you have already read my previous article titled Hazards in Confined Space, you will notice that confined space meaning is defined as a work area that has limited or restricted means for entry or exit and is not designed for continuous occupancy.

Other characteristics of a confined space are:

  • It contains harmful gases like H2S, carbon monoxide, etc.
  • Confined space oxygen level is low.
  • It contains material that may harm the person who enters it

The following are confined space examples that I collect from various resources. You can refer to that list to make your own confined space list.


Remember that confined space safety starts with a correct work area classification. Your wrong judgment will lead to improper safety precautions.

And this will cause an incident to occur.
