Tuesday Tip: Getting to know the confined space better
October 13, 2015Ansell | HérculesWithout CommentsTuesday Tip
We understand how important this activity is, and it gets even more serious when we deal with explosive atmospheres. Would you be able to identify a confined space, and what do you need to know to have reliable and proper equipment to make it a safe environment? In the next tips we will talk about this equipment, stay tuned!
1 – WHAT IS A CONFINED SPACE?
It is any area or environment not designed for continuous human occupation, which has limited means of entry and exit, and insufficient ventilation to remove contaminants or where there may be oxygen deficiency or enrichment.
2 – IS THE AREA CLASSIFIED?
Classified area is an area with a potentially explosive atmosphere or in which its occurrence is probable, and there may be concentration of gases, vapors, mists, and dusts forming an explosive atmosphere.
3 – WHAT IS THE VOLUME OF THE C.S.? (M³)
To know which equipment will best be of use, i.e., which equipment will have the most effective ventilation, we need to define the size of the confined space to make the ventilation sizing calculation.
4 – WHAT IS THE POWER SOURCE?
We supply equipment with voltage of 110 V and 225 V, which makes it necessary to know which voltage will be used.
5 – WHAT IS THE SIZE OF THE MANHOLE?
The information about the manhole size is required due to the diameter of the ducts used for ventilation. Reduced manholes may make it impossible to use ducts of certain diameters, thus, it must be evaluated whether or not it will be necessary to use a reducer.
