Concept glossary

SCBA
Self contained breathing apparatus.
Open Circuit SCBA
A type of SCBA where air flows from the cylinder through the facepiece and is discharged into the atmosphere.
Closed Circuit SCBA
A type of SCBA that filters, supplements, and recirculates exhaled gas and has an Oxygen Cylinder.
Escape Only SCBA
A type of SCBA designed for emergency escape situations with limited air supply.
Supplied Air Respirator (SAR) with Auxiliary Self-Contained Air Supply
A respirator system that supplies air from an external source with an auxiliary self-contained air supply for escape purposes.
CBRN NIOSH Approved
Certification indicating the SCBA is approved by NIOSH for Chemical, Biological, Radiological, and Nuclear protection.
Emergency Breathing Support System (EBSS)
A system required by NFPA 1981 for emergency breathing support.
Heads Up Display (HUD)
A display visible to the SCBA user in the facepiece that shows critical information.
