DESCRIPTION
The SCOTT PROFLOW FH22 Hood affords limited protection from contami-
nation caused by some liquid splashes or sprays while providing the
respiratory protection of filtered air from a SCOTT PROFLOW 3 Powered Air
Purifying Respirator (PAPR). The PROFLOW FH22 Hood consists of a poly-
ester coated synthetic fabric hood with inner and outer aprons, an integral
face shield, an adjustable head band, an integral exhalation port, and ac-
cess for attachment of the breathing tube for a PROFLOW 3 PAPR. An
optional Shroud to cover the Breathing Tube is available. This disposable
Hood and Shroud is intended for a SINGLE USE ONLY.
The PROFLOW FH22 Hood is unsuitable for exposure to certain chemicals or
for use in certain conditions. See the CHOOSING THE APPROPRIATE EQUIP-
MENT section of this instruction for details.
The PROFLOW FH22 Hood is available in a one-size to fit most as P/N
200676-01. This same hood is available in packaged quantities under the P/N
200676-XX where -XX denotes the quantity as packaged. The Breathing Tube,
P/N 31001207, is specially designed to connect to his hood. To facilitate de-
contamination of the breathing hose, an optional Hose Shroud to cover the
Breathing Tube, P/N 200677-01, is available, also sold in packaged quantities
where -XX denotes the quantity as packaged.
The PROFLOW FH22 Hood alone does not provide any protection against a
hazardous atmosphere. The PROFLOW FH22 Hood is part of a complete ap-
proved respirator which also includes, a PROFLOW 3 powered air purifying
respirator, the proper filtration media suitable for the hazardous atmosphere
where the respirator will be used, and the breathing tube to connect the Hood
to the PROFLOW 3 respirator. Refer to the NIOSH Approval Label included
with the PROFLOW 3 respirator for a complete listing of hoods and filters
approved for use with the SCOTT PROFLOW 3 respirator.
When used with a PROFLOW 3 PAPR, contaminated air is drawn through the
filtration elements mounted on the PROFLOW 3 blower unit and flows through
the breathing tube to the respiratory inlet on the back of the Hood. Air entering
the PROFLOW FH22 Hood is directed over the top of the head and down the
inner surface of the visor to prevent misting, then inhaled by the wearer. Ex-
haled air passes out through the integral exhalation opening between the inner
and outer aprons on the front of the PROFLOW FH22 Hood. The PROFLOW
FH22 Hood is intended to be used only with a PROFLOW 3 powered air puri-
fying respirator which can supply filtered breathing air at a rate of greater than
6 cubic feet (170 liters) per minute.
Refer to the user’s instructions provided with the SCOTT PROFLOW 3 Pow-
ered Air Purifying Respirator and to the most recent RESPIRATOR
APPROVAL LABEL for the complete respirator. Additional copies of the RES-
PIRATOR APPROVAL LABEL for the SCOTT PAPR are available from your
SCOTT distributor or by calling SCOTT Health and Safety at 1-800-247-
7257.
Do not use this equipment when anything might impair your ability to make
decisions about the safe operation of the equipment.

WARNING
THE MATERIALS THAT MAKE UP THE
PROFLOW FH22 HOOD ARE UNSUIT-
ABLE FOR EXPOSURE TO SOME
CHEMICALS. EXPOSURE OF THE
PROFLOW FH22 HOOD TO ANY OF
THESE CHEMICALS MAY CAUSE RAPID
FAILURE OF THE PROTECTIVE MATE-
RIAL EXPOSING THE USER TO THE
HAZARDOUS ENVIRONMENT WHICH
COULD LEAD TO SERIOUS INJURY OR
DEATH.
CHOOSING THE APPROPRIATE EQUIPMENT
Respirators reduce but do not eliminate all exposure to the hazardous atmo-
sphere. Some respirators are more effective than others at reducing exposure
depending on the nature and the concentration of the contaminant in the
hazardous atmosphere. When choosing a respirator, the respiratory protec-
tion program under which this respirator is to be used must determine the
appropriate level of protection that the respirator is expected to provide. Use
of inappropriate RESPIRATOR equipment for the work environment may
result in exposure to the hazardous atmosphere which may cause seri-
ous injury or death.
No material is perfectly resistant to all chemical substances. It is the re-
sponsibility of the respiratory protection program under which this equipment
is used to decide on a case by case basis the appropriateness, duration of
use, and re-use of the PROFLOW FH22 Hood.
The polyester coated synthetic fabric material used in the construction of
the PROFLOW FH22 Hood and Breathing Tube Cover is considered suit-
able for providing limited protection from the following:
The PROFLOW FH22 Hood material is considered UNSUITABLE for
providing protection from the following:
SCOTT PROFLOW FH22 PAPR Hoods must only be selected by persons
trained in evaluating the specific end-use conditions and in selecting the
appropriate chemical protective equipment. Consult a qualified industrial
hygienist for advice on the use of the PROFLOW FH22 PAPR Hood in your
work environment. Take into consideration that seams and closures often
have shorter breakthrough times and higher chemical permeation rates than
the fabric alone.
Anyone intending to use chemical protective equipment must first verify that
the equipment is suitable for the intended use as part of a complete respira-
tory protection program.
This hood and the breathing tube cover are intended only for a single use
and disposal after use, for example, after a single shift of work. Choosing to
clean and re-use this equipment is at the discretion and risk of the user and
the respiratory protection program.
SCOTT recommends that after use and before disposal, inspect the hood
material for signs of permeation or damage caused by chemical exposure. If
there is evidence of permeation:
·Refer to the Material Safety data Sheet (MSDS) for the chemicals in-
volved for information about the possible hazards of exposure,
·Consider whether this hood material is suitable for your particular appli-
cation.

WARNING
THE PROFLOW FH22 HOOD IS NOT IN-
TENDED FOR USE IN FIRE FIGHTING OR
OTHER HIGH TEMPERATURE OPERA-
TIONS WHERE THE AMBIENT
TEMPERATURE COULD BE ABOVE 150°
F / 65° C. USE OF THE PROFLOW FH22
HOOD IN HIGH TEMPERATURES MAY
RESULT IN FAILURE OF THE PROTEC-
TIVE MATERIAL, EXPOSING THE USER
TO THE HAZARDOUS ENVIRONMENT
RESULTING IN BURNS, SERIOUS IN-
JURY OR DEATH.
REGULAR OPERATIONAL INSPECTION
The PROFLOW FH22 Hood must be inspected when first received and before
each use of the PROFLOW FH22 Hood with the respirator. If the PROFLOW
FH22 Hood is stored for emergency use, it must be inspected regularly. If any
discrepancies are found, remove the PROFLOW FH22 Hood from service and
tag for repair or replacement as required. Inspect as follows:
1. Inspect the PROFLOW FH22 Hood for any holes or tears in the fabric.
2. Verify that all seams and joints are secure and show no signs of weakening
or breakdown.
3. If not already removed, remove the protective paper from the front of the
visor window.
4. Check the visor window for cracks and damage to the perimeter seal. Check
the visor window for scratches which might interfere with visibility.
5. Check the exhalation port and channels to make sure there is no damage
that would interfere with the movement of exhaled air.
6. Verify that the inner elastic head band is secure and that the elastic head
size adjustment cord and cord lock are operating properly.
7. Check the neck cord and the cord lock for completeness and operation.
Check the neck cord channel for tears in the seams.
8. Check the attachment of the breathing tube to the hood. Verify that the
washer is in place and that the fabric is flat and not wrinkled. Verify that the
nut is hand tight.
9. Inspect the breathing tube for any damage including holes in the side wall,
crushed internal coil, or separation of either end. If any damage is found,
replace the breathing tube before use of the respirator.
10. Inspect the gasket inside of the female end of the breathing tube. Do not
use the breathing tube with a missing or damaged gasket. Remove the
breathing tube from service and tag for repair by authorized personnel.
If any damage or discrepancies are found, remove the PROFLOW FH22 Hood
from service and tag for disposal and replacement.
In addition, the materials used in these hoods are not suitable for use in high
temperature applications, like fire fighting. Exposure to high ambient tem-
peratures above 150° F / 65° C may cause the protective materials to fail.
The respiratory protection program must also take into consideration the
levels of exposure which may be hazardous irrespective of respiratory pro-
tection (e.g.: contaminants which are toxic through exposure to unprotected
skin). Additional protective equipment such as apparel may be required.
However, any additional protective equipment must not interfere with ac-
cess to or operation of the respirator.
When properly attached to a SCOTT PROFLOW 3 respirator, the PROFLOW
FH22 Hood provides limited protection from airborne contaminants to only
the head, neck, throat, and upper chest areas of the user. The using em-
ployer or agency must provide the appropriate protective clothing for use
with this equipment and must insure that protective clothing will not interfere
with the operation of the respirator or the hood. The user must insure that
the PROFLOW FH22 Hood, the PROFLOW 3 respirator and the protective
clothing are properly donned and operating correctly. Do not wear any other
head gear over or under the PROFLOW FH22 Hood.
This equipment is not intended for use in atmospheres which are or may
become IMMEDIATELY DANGEROUS TO LIFE OR HEALTH (IDLH), in HIGH
TEMPERATURE ENVIRONMENTS, or in ATMOSPHERES WHERE THE
IDENTITY AND/OR CONCENTRATION OF THE CONTAMINANT IS UN-
KNOWN. This equipment is only for use in atmospheres from which the
user may safely escape without the use of the respirator.
This hood is intended only for a single use and disposal after use, for ex-
ample, after a single shift of work. Choosing to clean and re-use this hood is
at the discretion and risk of the user and the respiratory protection program.
