Extra Air Connection; Rescue Hose; Usage With Airline System - INTERSPIRO Incurve Bedienungsanleitung

10. EXTRA AIR CONNECTION

Some models are equipped with an extra air connection which can be used to:
connect to a chemical suit ventilation system
1.
connect a rescue hose between two apparatus
2.
connect an extra mask
3.
connect the resuscitation mask Revitox or the EVAC evacuation hood
4.
feed the apparatus from an external air source
5.
When taking air from the appartus, point 1-4 above, the air consumption increases
and the duration of the apparatus decreases.
A special female coupling with a non-return valve opener must be used when taking
air from the apparatus, point 1-4 above. This device openes the non-return valve in the
male connection on the apparatus.
When feeding the apparatus from an external air source, this kind of female coupling
must not be used. In this application, the non-return valve in the male connection
must be able to close in case of disruption in air supply from the external source.

11. RESCUE HOSE

The apparatus may be equipped with a rescue hose that can be used to share air
between two users in an emergency.
A user with a lot of air (donor) shares his air with a user with little air (receiver). But
the air will not only be taken from the donor when you have connected the devices.
The air will be consumed from both apparatuses and may be taken alternately from
the different appratuses depending on variations in the regulator pressure and the
breathing rhythm of the users.
The rescue hose is mounted according to [Fig. 20]. To use the rescue hose, grasp the
Y-coupling and pull the hose free from its attachment.
The rescue hose has a male and a female connection so that they can be connected
together.
NOTE! ALWAYS FOLLOW YOUR ORGANIZATION'S ESTABLISHED PROCEDURES FOR RESCUE HOSE USE.

12. USAGE WITH AIRLINE SYSTEM

When operating on supplied air from the airline hose, the cylinder valve on the SCBA
should be closed.
Should the supply from the airline hose be disrupted, fully open the cylinder valve of
the SCBA.
When the cylinder valve has been opened, the user must immediately leave the
hazardous area. Disconnect the airline hose if necessary.
