Service and test the breathing apparatus, including out-of-use apparatus,
in accordance with the maintenance table. Record all service details and
testing. Refer also to the instructions for use for the lung demand regulator,
face mask and other associated equipment.
Additional inspection and testing may be required in the country of use to ensure
compliance with national regulations.

Extend the shoulder straps, waist belt and the straps of the face mask.
For storage, place the face mask in a protective bag (contact Dräger
for supply of a suitable bag).
Route rubber hoses in such a way that the bend radius is not too acute
and the hose is not stretched, compressed or twisted.
With the system switched off, a small amount of battery power is
consumed. If the system is not to be used for a long period, remove the

Store the equipment between 5 °F to 77 °F (-15 °C to +25 °C). Ensure
that the environment is dry, free from dust and dirt, and does not
subject the equipment to wear or damage due to abrasion. Do not
store the equipment in direct sunlight.
Fix the breathing apparatus securely to any raised mounting point to
prevent it from falling.

Dispose of used batteries in accordance with national or local regulations.
When required, dispose of other parts of the breathing apparatus, including
electrical and electronic equipment, in line with any national or local
environmental regulations.

WARNING
Air quality must conform to the statutory requirements.
Use of a Universal Emergency Breathing Support System (EBSS) must
comply with NIOSH and NFPA 1981 requirements
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 Respiratory Protection
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)
Airline flow rate: 550 liters/minute
Cold temperature approval of -25 °F (-31.7 °C).
NOTICE
Sentinel 7000 alarms and warning signals will operate as normal. The
user interface display will show cylinder pressure when the cylinder valve
is open.
1. Turn on the independent air supply.
2. Connect the independent air supply coupling to the secondary supply
hose (see the EBSS/SAR Connection instructions for use) and breathe
normally.
3. Close the cylinder valve (if the whistle sounds, silence it by taking
several short deep breaths or momentarily operating the lung demand
regulator bypass button (Fig C, Item 3).
4. If any air supply problems are encountered, proceed as follows:
a. Open the cylinder valve to return to breathing from the attached
cylinder.
b. Disconnect the independent air supply coupling.
c. Leave the hazardous area by the shortest and safest escape
route, if necessary.
