SYSTEM DESCRIPTION

The 3M™ Powerflow Face Mounted Powered Air Respirator System
7900PF is designed to provide respiratory protection against solid and
non-volatile liquid particles only.
This product meets the requirements of EN 12942 (power assisted
devices incorporating full face masks).
Air is supplied to the wearer thus reducing fatigue associated with
inhaling unassisted through the filter.
Should the Powered Air Turbo fail or the battery charge fall during use
the wearer is provided with a reduced level of protection to enable safe
exit from the contaminated area.
APPROVALS
These products meet the requirements of the European Community
Directive 89/686/EEC (Personal Protective Equipment Directive) and are
thus CE marked.
Certification under Article 10, EC Type-Examination and Article 11, EC
quality control, has been issued for systems incorporating these products
by BSI, Kitemark Court, Davy Avenue, Knowlhill, Milton Keynes MK5

This product complies with the European EMC Directive 2004/108/EC.
^ WARNINGS AND LIMITATIONS
Proper selection, training, use and appropriate maintenance are
essential in order for the product to help protect the wearer from
certain airborne contaminants. Failure to follow all instructions
on the use of these respiratory protection products and/or failure
to properly wear the complete product during all periods of
exposure may adversely affect the wearer's health, lead to
severe or life threatening illness or permanent disability.
For suitability and proper use follow local regulations, refer to all
information supplied or contact a safety professional or 3M on 0870
60 800 60 (UK) or 1800 320 500 (Ireland).
Use this respirator system strictly in accordance with all instructions:
• contained in this booklet
• accompanying other components of the system (e.g. 3M™ Filter and
3M™ Facepiece User Instructions)
See all instructions for use and save for continuing reference.
Do not use in concentrations of contaminant above 40 times the
Workplace Exposure Limit (WEL).
Do not use for respiratory protection against unknown atmospheric
contaminants or when concentrations of contaminants are unknown
or immediately dangerous to life or health (IDLH).
Do not use in atmospheres containing less than 19.5% oxygen. (3M
definition. Individual countries may apply their own limits on oxygen
deficiency. Seek advice if in doubt).
Only use with the spares and accessories listed and within the usage
conditions given in the Technical Specification.
Only for use by trained, competent personnel.
Leave the contaminated area immediately if:
a) Any part of the system becomes damaged.
b) Airflow to the facepiece decreases or stops.
c) Breathing becomes difficult or increased breathing resistance
occurs.
d) Dizziness or other distress occurs.
e) You smell or taste contaminants or irritation occurs.
Never modify or alter this product. Replace parts only with original 3M
spare parts.
Do not use in flammable atmospheres.
Select and wear appropriate protection when exposed to sparks
and/or flames.
In case of intended use in explosive atmospheres, contact 3M
Technical Service.
Do not use with beards or other facial hair that may inhibit
contact between the face and the product thus preventing a
good seal.
Very high work rates (where the pressure within the facepiece can
become negative) can reduce protection.
Adjust equipment as appropriate or consider an alternative form of
respiratory protective device.
Materials which may come into contact with the wearer's skin are not
known to cause allergic reactions to the majority of individuals.
These products do not contain components made from natural rubber
latex.
Only use with the spectacle kit available as an accessory with this
product, and ensure spectacle arms do not interfere with the faceseal.
Safe Use of Battery Chargers
To reduce exposure to hazardous voltage:
- Do not use the chargers outdoors or in wet environments.
- Do not attempt to service the chargers. There are no
user-serviceable parts inside.
- Inspect the chargers and power cords before use. Replace if any
parts are damaged.
- Do not substitute, modify or add parts to the chargers.
To ensure safe charging of batteries, only use combinations of
batteries and chargers as specified on the reference leaflet.
Safe Use of Rechargeable Lithium Batteries
Lithium cells are very high-energy systems and as such must be
treated with care. The following safety considerations should be
observed:
Battery packs should not be exposed to temperatures in excess of
70°C (158°F).
Particular care should be taken that battery packs are not overloaded
or shorted.
Do not attempt to discharge the battery pack in any system other than
specified in this user instruction.
Do not force discharge battery packs as this may result in
overheating, venting and release of materials.
Do not open, puncture, drop, deform, crush or tamper with battery
packs as this could result in the release of materials. In the event that
a battery is accidentally ruptured, for whatever reason, contact
OH&ES Technical Affairs at your local 3M office.
Never use Lithium batteries in a completely sealed pressure
container.
In the event that a battery pack is short circuited accidentally or starts
to heat up for no apparent reason then, where possible, it should be
disconnected immediately and removed to a well ventilated or outdoor
area and allowed to cool. Where it is not possible or practical to
disconnect the battery pack, clear the area until such time as any
activity has subsided. Once stabilized to a safe condition the battery
pack may be disposed of. For any further advice contact OH&ES
Technical Service at your local 3M office.
Suitable protective clothing should be worn when handling suspect
battery packs.
