Confined spaces Definition In this article we will discuss the definition of confined spaces. After reading this article, it is hoped that you can easily recognize confined spaces within the plant site and ensure adequate risk control against risks of confined spaces.
By definition, confined spaces ie spaces that are large enough spaces where workers can enter and perform assigned work injury. Confined spaces, which can be easily found in the chemical plant site, at least have the following characteristics:
a. Have limited or restricted openings / means of entry and exit.
b. It is not designed and intended for the occupation of workers continues.
C. Poor natural ventilation.
As defined above, we should be able to identify all confined spaces exist in the plant site. And I think we can easily identify them. Below are examples of confined spaces commonly found in a chemical plant site. I recommend you go to the plant site or the processing equipment lists to identify confined spaces in your plant.
1. solvent reservoirs
2. Pressure vessels
3. Boiler
4. Reaction towers
5. distillation towers
6. Storage Tanks
7. hopper Catalyst
8. gasometer
9. Water tank
10. sewage tank
11. absorption column
12. Oven
13. Asher
14. exchange column resin
15. Wide range of pipe
16. bulk chemical containers
I have many experiences working in confined spaces during my assign work to the site of the chemical plant. Storage tanks, pressure vessels and reactors are some confined spaces where I entered. Special precautions should be fully given when working in confined spaces, otherwise an accident may occur.
What you must always keep in mind is to put special attention when working in confined spaces.
