Special instructions

Use of an Independent Air Supply (SAR Airline Connection)
! Air quality must conform to the statutory requirements.
Use of an airline connection by a second person (buddy-breather) voids NIOSH
approval.
The time required for the wearer to escape to a safe area must be within the remaining
breathing time of the cylinder, taking into account the remaining air content in the
cylinder and the breathing rate of the wearer.
Independent air supplies must meet the following standards:
Type-1 gaseous air as defined in: CGA Commodity Specification for Air, G-71 (grade
D or higher)
NFPA 1989 Standard on Breathing Air Quality for Fire and Emergency Services

Air supply pressure – 87 psi to 125 psi
Airline hose length – 5 feet to 300 feet (maximum working hose length must not exceed
12 individual hose lengths)
