Confined space entry definitions

This example clearly illustrates the reasoning and the logic behind OSHA s ensuring that the definition of confined "entry" (discussed in detail later) includes clear language defining what constitutes "entry"— that is, when any part of the entrant s body breaks the plane of an opening into the space, an entry has been made and is subject to the confined space entry regulations.

A vessel large enough for entry will almost certainly come under OSHA s definition of a "confined space." Regulations and permits for such work are covered in Sections 4.5.1 and 7.1.4. 

Metal container curing ovens meet the definition of a PRCS. Therefore, employee entry into such spaces must be conducted in compliance with the PRCS standard. An employer who eliminates the hazards from a permit space, as provided by paragraph (c)(7) of the standard, can reclassify that space as a non-permit confined space. That reclassification, which would remain In effect as long as the hazards remain eliminated, would allow employers to have employees enter the curing ovens without implementing a permit space program. 

In Brazil the most recurrent definition Confined Space is the one that appears in NR 33—Security and Health at Work in Confined (2006) Spaces with its latest update by MTE Ordinance No. 1409, August 29, 2012 Confined Space is any area or environment not designed for human occupancy continues, having limited means of entry and exit, whose existing ventilation is insufficient to remove contaminants or where there might be a deficiency or oxygen enrichment.
