Now we get into area that MIGHT require respiratory protection. However, always remember this:

Just because it is a permitted confined space does not mean SCBA or even any other form of respirator is required.

Remember, permitted confined space has one or more of these attributes:

1. It contains or has the potential to contain a hazardous atmosphere;
2. It contains materials that POTENTIALLY could engulf ANYONE in the space;
3. It has a design that potentially could trap or asphyxiate anyone in the space; and
4. It contains any other SERIOUS safety or acute HEALTH hazard.

The reason an SCBA is often needed for entry into a permitted confined space is because nothing has been done to characterize what is the potential or real atmospheric hazard. If you do not know, then an SCBA is required.
