Notes
O Dräger recommendations
1 Clean the equipment if it is dirty. If the equipment has been exposed to
contaminants, disinfect any components that come into direct and
prolonged contact with the skin.
2 These maintenance tasks may only be carried out by Dräger or trained
service personnel. Details of the tests are contained in the Technical
Manual which is issued to service personnel that have attended a
relevant Dräger maintenance course.

8.2 Storage conditions
● 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.
● If storing the equipment in a vehicle, ensure that the breathing

11 Special instructions
11.1 Use of an independent air supply (supplied
airline respirator (SAR) connection)
WARNING
Air quality must conform to the statutory 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.
● Minimum ambient temperature of operation: -25 °F (-31.7 °C).
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 UEBSS/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
valve bypass button (Fig J, 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.
11.2 CBRN use
The Dräger PSS 5000 Series is certified by National Institute for
Occupational Safety and Health (NIOSH), for chemical, biological,
radiological or nuclear (CBRN) use and by the Safety Equipment Institute
(SEI) to meet the requirements of NFPA 1981. Approvals are only valid
when the apparatus is used with compressed-air cylinders approved by
NIOSH. Equipment configurations for CBRN use are detailed in a CBRN
Approval Label (see CBRN Approval Label 3367113).
Dräger recommend that a quantitative fit test (QNFT) be performed on the
face mask before use in a CBRN environment. The fit test must be
conducted strictly in accordance with the requirements outlined in the
OSHA Respiratory Protection Standard 29 CFR, Section 1910.134.
11.3 Cautions and limitations
CAUTIONS AND LIMITATIONS
D – Air-line respirators can be used only when the respirators are supplied
with respirable air meeting the requirements of CGA G – 7.1, Grade D
or higher quality.
E – Use only the pressure ranges and hose lengths specified in the
USER'S INSTRUCTIONS.
I – Contains electrical parts that may cause an ignition in flammable or
explosive atmospheres.
J – Failure to properly use and maintain this product could result in injury
or death.
M – All approved respirators shall be selected, fitted, used, and
maintained in accordance with MSHA, OSHA, and other applicable
regulations.
