Safety Considerations
IMMEDIATELY STOP WORK IF PERSONAL PROTECTIVE
EQUIPMENT (PPE) FAILS. If any item of the personal
protective equipment ensemble fails during use,
immediately cease work activity, retreat from hazard zone,
safely remove the PPE (may require decontamination
procedure), determine the cause of the PPE failure and re-
evaluate the selection and use of the PPE for that task.
Be sure to read, understand and follow the information in
this manual and all applicable governmental occupation
safety and health statutes. Serious injury or death may occur
from improper use of these garments. These garments must
be selected and used in accordance with applicable personal
protective equipment regulations, which in the United States
is 29 CFR 1910.132. For users of these garments outside
of the United States, consult national or other applicable
personal protective equipment laws and regulations.
Users must read this guide thoroughly and should take the
following precautions into consideration:
• Avoid ame contact. These suits are not intended for
exposure to an open ame; however, Tychem® 10000 FR
(Tychem®Reector®) model RF600T and Tychem®
10000 (Tychem®TK) models TK600T and TK601T (worn
with over cover provided) have been tested and certied
to the ash re escape option of NFPA 1991, Standard
on Vapor-Protective Ensembles for Hazardous Materials
Emergencies.
• Do not knowingly enter an environment in which the
concentration of ammable gas/vapor or combustible
dust is within ammable or explosive limits when
wearing a Tychem®garment, including RF600T, TK600T,
and TK601T. Retreat immediately if you encounter such
an environment.
• No Tychem®garment, including RF600T, TK600T, and
TK601T, is intended for re-ghting activities, nor for
protection from hot liquids, steam, molten metals,
welding, or thermal radiation. However, Tychem®
6000 FR (Tychem®ThermoPro) fabric was tested to
EN ISO 11612:2015 (Protective clothing — Clothing
to protect against heat and ame — Minimum
performance requirements) and was rated as Class D1
for molten aluminum and Class E2 for molten iron.
• Good practice is to minimize, as much as possible,
continuous exposure to any known hazardous
substance.
• If you develop any of the following symptoms while you
are wearing a Tychem®garment immediately leave the
contaminated area, undergo eld decontamination, and
remove (doff) the garment:
Fever Unusual odor or taste
Difculty breathing Eye or skin irritation
Nausea Narrowing or dimming of vision
Excessive Tiredness Claustrophobia
Dizziness Loss of balance or orientation
Numbness
Tychem®garments will not protect the wearer in all
situations and environments or protect the wearer from
all hazardous materials. A trained and qualied safety
professional must select the chemical protective clothing
and other PPE based on a hazard assessment. It is your
responsibility as a user of this garment to determine
the level of exposure and the proper personal protective
equipment needed. Many performance properties cannot
be tested by the users in the eld. Refer to DuPont™
SafeSPEC™(www.safespec.dupont.com) for information
regarding performance data for Tychem®Level A and Level B
Encapsulating suits.
Wearer Qualications
Do not wear these garments unless you are properly trained
in their use. You must be in good physical condition to wear
these garments. Consult a physician before donning one of
these garments to ensure you are capable of wearing these
garments and all required respiratory equipment under the
expected work conditions and environment.
Encapsulating Design Garments
Per EPA/OSHA guidelines, encapsulating suits may be
considered either Level A or Level B. Encapsulating
garments that pass the ination test described in ASTM
F1052, Standard Test Method for Pressure Testing Vapor
Protective Ensembles, are considered Level A. Encapsulating
garments that are not designed to pass ASTM F1052 are
considered Level B.

4
User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
Breathing Air Requirements for Encapsulating
Design Garments
Encapsulating garments are designed to completely cover
the wearer, including all respiratory equipment (except
for external air supply lines, if applicable). Encapsulating
garments require that fresh breathing air be supplied to the
wearer at all times.
CAUTION: YOU MUST USE AN OPEN CIRCUIT SELF-
CONTAINED BREATHING APPARATUS OR AIR-LINE
SUPPLIED RESPIRATOR WITH ALL ENCAPSULATING
GARMENTS.
Other Personal Protective Equipment
To help protect you while wearing a Tychem®garment, the
use of other personal protective equipment (PPE) items
is often required based on the hazard assessment. PPE
selection must be conducted by a trained and experienced
safety professional. Additional protective equipment may be
required to deal with hazards such as, but not limited to, the
following:
• Flammable or Explosive Environment
• Extreme Heat (Heat Stress)
• Extreme Cold (Hypothermia)
• Physical Hazards (Sharps, Puncture, Rough Surfaces,
Falling Debris)
• Slipping Hazards
• Visibility Requirements
• Fall Protection
• Contamination Avoidance
Respirators
Tychem®encapsulating suits must be worn with a full
face, supplied air respirator. The user must be trained and
physically t to use a respirator. The performance of your
respirator must be veried with a performance based t
test. Failure to properly select, test, use and maintain your
respirator can result in serious injury or death. The selection
of the appropriate respirator is the responsibility of the
safety professional or industrial hygienist.
The full face, supplied air respirator worn with encapsulating
Level A or Level B Tychem®garments must include:
• An open circuit, self-contained breathing apparatus
(SCBA) certied as compliant with NFPA 1981,
“Standard on Open-Circuit Self-Contained Breathing
Apparatus for Fire Service“
or
• An external, breathing air-quality, air-line system with
garment pass-through and escape bottle.
Do not wear a closed-circuit (rebreather-type) SCBA with
Tychem®encapsulating Level A or encapsulating Level B
garments. Do not wear an air-purifying respirator (APR) or
a powered, air-purifying respirator (PAPR) inside a Tychem®
encapsulating Level A or encapsulating Level B suit.
Over Covers
Use of the provided over cover is required to be worn with
Tychem® 10000 (Tychem®TK) models TK600T and TK601T.
Footwear
You must wear separate, user-supplied, protective footwear.
The socks attached to encapsulated Level A and Level
B Tychem®garments must be worn inside protective
footwear. Failure to wear appropriate user supplied
footwear will damage the attached sock. It is the user’s
responsibility to verify that appropriate footwear has been
selected and used based on a hazard assessment. For
NFPA certied Tychem®encapsulated ensembles, refer to
the appropriate Technical Data Package for a list of approved
footwear for use with those ensembles.
Gloves
All Tychem®Level A suits have attached chemical resistant
glove systems. Tychem®Level B encapsulating suits may or
may not have attached glove systems. For NFPA certied
suits, refer to the Technical Data Package for glove system
information. For non-certied encapsulated Level A or Level
B suits contact DuPont for information regarding glove
system details for specic suit models. It is the user’s
responsibility to verify that appropriate gloves have been
selected and used based on a hazard assessment.

User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
Garment Inspection, Maintenance, and Testing
Garment Inspection
The wearer must inspect all encapsulated Tychem®garments
at the following times to determine that the suit has not
been damaged or compromised:
See Garment Maintenance Schedule (Table 1).
1. Immediately upon receipt from supplier.
2 Before it is placed in service to be worn.
3. After a garment is worn and before the garment
is placed in service to be worn again. Do not use
contaminated, damaged or altered garments.
4 Inspect annually.
Garment Inspection Steps:
1. Lay the garment on a clean, smooth surface.
2. The inspection should include all areas of the suit: body,
visor, and gloves (if present).
3. Use a ashlight inside the suit to examine for holes,
cuts, or tears. Conrm that any suspected visual
imperfection is actually a void by using a small amount
of water to conrm penetration.
NOTE: Visible stitch holes which are covered by seam
sealing tape do not constitute a defect.
4. Examine all taped seam areas for proper seal. Look for
areas where seam tape has lifted away from the suit or
where seam tape does not fully cover stitch holes.

5. Examine the entire garment for signs of damage. A
breach, rupture, or hole of any component of the suit is
cause for rejection. Note that the fabric, visor, gloves,
or seams may have visual blemishes that do not affect
barrier performance. Such blemishes can include areas
adjacent to the seam tape that appear to be dull, white,
or frosted.
6. Examine the visor to ensure it offers a clear visual eld.
7. If the garment includes a pass thru option, examine the
garment’s air distribution system to ensure that there
are no obstructions and that it is connected properly
and is in proper working order.
8. Examine the garment gloves (if present) to ensure that
they are in good condition and properly attached to the
suit. Gently pull on the gloves to ensure that they are
rmly attached to the suit.
NOTE: You can potentially damage the gloves by pulling
with excessive force.
9. Examine the garment zipper and zipper cover to make
sure they are in good working order. Operate the zipper.
Lubricate the zipper using parafn wax, if needed.
Engage the hook and loop tape on the zipper storm
aps to ensure appropriate adhesion.
10. Examine all garment snaps, etc. to ensure they are in
good working order.
11. Examine garment labels to ensure they are rmly
attached and are legible.
On September 1, 2013 DuPont stopped installing Auer valves into Tychem®Level A suits. Auer valves require the valve diaphragm to be replaced
at least every 2 years. Replacement Auer valve diaphragms can be obtained for existing Tychem®Level A suits by contacting DuPont. Pirelli valve
diaphragms do not have a mandatory 2 year replacement cycle.

6
User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
12. There is a diaphragm in each exhaust valve in Level
A suits that must be inspected and replaced by the
end user if damaged. Inspection of these diaphragms
should occur, at a minimum, at the time of the ination
test because the exhaust valve diaphragms must be
removed to perform the ination test. After removing
the exhaust valve diaphragms, visually inspect
them using a magnifying glass to look for cracks
or deterioration. Replace damaged or deteriorated
diaphragms. Instructions for purchasing replacement
exhaust valve diaphragms can be found at www.
safespec.dupont.com or by contacting DuPont
Customer Service at 800-931-3456. Instructions for
replacing the exhaust valve diaphragm can be found in
the DuPont Instruction Manual for Universal Pressure
Test Kit.
13. For Level A garments, perform an ination test as
described below. Instructional videos can also be found
on www.personalprotection.dupont.com.
NOTE: Encapsulated Level B suits do not require an
ination test.
Cleaning
Garments, except Tychem®2000 SFR and Tychem®6000
SFR garments, that are not contaminated with hazardous
substances can be cleaned. Use water, mild dishwashing
liquid, a soft brush, and hand towel to remove the non-
hazardous substance that soiled the garment. Thoroughly
rinse the garments with clean water and allow it to air-dry.
Do not dry-clean or machine-wash these garments. Do not
use hot air or a tumbling air dryer to dry these garments. Do
not use bleach or harsh cleaning agents on these garments
if they are intended to be re-used. Cleaning procedures
are not an acceptable procedure for decontamination (See
Section on Field Decontamination). The user should develop
and implement a decontamination procedure for all the
chemicals to which the suit has been exposed. Tychem®
2000 SFR and Tychem®6000 SFR garments should not be
cleaned or laundered; dispose of them after use.
Pressure Testing Level A Tychem®Garments
The air-ination test evaluates the gas tight integrity of
Tychem®Level A garments.
All DuPont™Tychem®Level A garments made after
September 2013 are equipped with Pirelli exhaust valves.
Prior to September 2013, Tychem® 10000 (Tychem®TK),
Tychem® 9000 (Tychem®BR), and Tychem®LV Level A
garments were equipped with either Auer or Pirelli exhaust
valves. Please refer to the images below to determine which
valve is on the suit. Auer valves are tted with a exible outer
“snorkel” cover that opens at a right angle to the throat of
the exhaust valve. Pirelli valves are tted with a rigid outer
cover that is perforated with small holes (Figure 1).
Figure: 1
Conduct ination tests according to ASTM F1052, “Standard
Test Method for Pressure Testing Vapor Protective
Ensembles”. A copy of the standard may be obtained from
ASTM (www.ASTM.org) or by calling ASTM at (877) 909-
2786 or [phone].
Read, understand and follow the instructions in the DuPont

User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
Record the results of each ination test on the log sheet
provided with your garment. You can also nd a blank log
sheet at the end of this document.
In the event that a Level A suit does not pass a pressure
test, the following should be checked before contacting
DuPont.
1. Conrm that the pressure test kit is functioning properly
using the self test adapter and following the step by
step video, Calibrating the Pressure Test Kit, found on
www.personalprotection.dupont.com in the library
section for any Level A suit.
2. Conrm the vapor tight zipper is fully seated in the
closed position.
3. Check the tightness of all exhaust valve pressure test
adapters. Adapters must be rmly seated in the valves.
4. Conrm the tightness of each exhaust valve body to suit
fabric. It may be useful to fully remove each valve by
unscrewing the two body halves, inspecting all seating
areas for obstructions or fabric wrinkles, and carefully
reassembling and hand tightening.
5. Perform another pressure test procedure after each of
these areas has been checked.
Closure Lubricants
The wearer can lubricate a zipper closure that is difcult
to operate. Apply parafn wax lightly on the teeth of the
closure while open. After lubricant is applied, close and open
the zipper several times to ensure smooth function and to
remove excess lubricant.
NOTE: EXCESSIVE FORCE OR IMPROPER TECHNIQUE
CAN DAMAGE THE GAS-TIGHT ZIPPERS IN LEVEL A
SUITS. When opening or closing the zipper, use one hand
to hold the zipper assembly near the slider while pulling the
slider in a direction that is parallel to the line of the zipper
assembly. Using excessive force or not pulling the slider in
the direction of the zipper installation can lead to permanent
damage to the zipper which negatively affects the garment’s
gas tight seal.
Garment Repair
Do not use a damaged, altered, or contaminated garment.
If an uncontaminated or unaltered garment fails a visual
inspection or ination test, contact the distributor from
whom you purchased the suit or DuPont Personal Protection
at 800-931-3456 to determine if the garment can be returned
for repair. Note: Charges may be incurred; refer to the
warranty section in this document.
Contaminated garments will not be accepted for repair.
With each returned garment, you must provide the garment
testing log and a declaration that the garment has not been
exposed to chemicals or to biological pathogens. DO NOT
RETURN A GARMENT WITHOUT PRIOR AUTHORIZATION
FROM DUPONT PERSONAL PROTECTION CUSTOMER
SERVICE.
Glove Replacement
Contact DuPont Personal Protection at 800-931-3456 to
determine if the attached gloves on your garment can be
replaced.
Recommended Duration of Use
Tychem®Level A and Tychem®Level B encapsulating suits
may be used for 5 years from date of manufacture as long
as all of the following conditions are met:
1. The suit has been stored properly (see section on
Storage Conditions)
2. The suit has not been damaged, altered, or
contaminated
3. The suit passes a full visual inspection (as outlined
above)
4. For Level A suits, the suit must also pass the ASTM
F1052 ination test.
After 5 years, if all of the above conditions are met, it is at
the sole discretion of the end-user whether to continue
using the suit or to retire the suit. It is suggested that
garments be labeled and retired to “Training Use Only” after
5 years. DuPont™Tychem®Level A and Level B encapsulating
suits may contain materials such as gloves and closures for
which there is no specic storage life data available.
Uncontaminated garments that do not pass a visual
inspection and/or do not pass the ination test (for Level A
garments) should be retired from service and labeled “For
Training Use Only” or discarded after mutilation.

8
User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
Storage Conditions
Store Tychem®garments in a cool, dark, dry location free
of dirt and insects. Sunlight, ozone, high temperatures
(>120 °F), exhaust fumes, compression under heavy weight
and/or sharp protrusions are some conditions known to
degrade or damage the materials in these suits.
Store Tychem®Level A and Level B encapsulating garments
in boxes, in bags, or on hangers. Never step on or place
heavy objects on top of chemical garments.
Sizing Considerations
Verify the t of your Tychem®garment before actual use. Use
the sizing chart found at the end of this document to select
the appropriate size based on height and weight. Obtain
the size suit you intend to wear, don that size garment, and
perform a series of exercises to simulate your movements
under actual work conditions. A garment larger or smaller
than suggested in the chart may be preferred. Sizing t tests
must include outer boots, head protection and other PPE
and accessories that the wearer will use during actual use.
Donning Encapsulating Level A and B Garments
A donning training video for Tychem®encapsulating suits is
available at www.personalprotection.dupont.com.
Have another person present when donning your chemical
protective ensemble. Use a stable chair, bench, or stool
which is free of sharp edges. If outdoors or where the
ooring is rough, use a ground cloth to avoid damaging your
garment.
1. Conduct a visual inspection of the garment as described
above before beginning the donning steps
Ensure that the inner gloves (if applicable) are fully
inserted into the outer gloves (if applicable).
Check that the inside and outside of all exhaust valves
are free of obstructions such as caps, plugs, tape, or
foam padding.
2. Remove all jewelry and personal items (pens, key rings,
badges, pagers, knife cases, etc.) that might damage
the garment.
3. Check function of your respirator system per the
manufacturer’s instructions and place near donning
location.
4. Inspect outer boots per the manufacturer’s instructions
and place them nearby.
5. Open the garment closure completely.
6. Check the garment size label to verify the suit meets
your requirements.
7. Apply an antifogging solution to inside surface of the
visor (if desired).
8. Remove your shoes. If the garment has attached socks,
these socks are to be worn inside outer chemical boots
(not provided with the Tychem®suit). The attached socks
do not have adequate durability or slip resistance to be
worn as the outer footwear covering.
9. While sitting, insert your feet into the garment legs and
down into the attached socks, if so equipped. Stretch
your legs to maximum extension while pulling garment
up. Don outer chemical boots. If the garment is tted
with boot ap covers, pull boot ap covers up and don
your outer boots. Then pull the boot ap covers down
over the outer boots as far as possible.
10. Stand and continue pulling the garment up to your
hips and connect and adjust the garment waist belt (if
equipped) until comfortably snug.
11. While standing, with garment at waist level, don your
respirator air tank.
12. Don your respirator face piece and check its function.
To conserve SCBA air supply, disconnect the air supply
from the face piece when the garment zipper closure
is open and you have access to fresh air. In the case of
an external airline breathing system, complete all other
connections and adjustments.
13. Don protective headgear and communication equipment
as appropriate.

9
User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
14. Connect the respirator face piece to the breathing air
supply and make sure the respirator is functioning
properly. Continue on supplied breathing air for rest of
the donning steps.
15. Place one hand and arm into its sleeve and pull the
garment sleeve to your shoulder. Make sure your hand
is securely inside the glove(s), if attached.
16. Place your other hand and arm into its sleeve and pull
the garment sleeve to your shoulder. Make sure your
hand is securely inside the glove(s), if attached.
17. If gloves are not attached to the garment, next don
your gloves. Pull the sleeves of the garment over the
gauntlet of the gloves. Do not rely on taping to provide
a liquid-tight or gas-tight seal. Only use tape to hold the
sleeve in position over the glove gauntlet. If a leak-proof
seal between the glove and sleeve is required, then
wear a garment with attached gloves.
18. Pull the garment over the respirator back air tank (if
present) and over your head making sure nothing will
constrict or hamper breathing air ow or respirator face
piece seal.
19. Have your assistant slowly close the suit zipper fully.
20. Have your assistant carefully close and secure the aps
over the zipper.
Dong Encapsulating Level A and B Garments
A dofng training video for Tychem®encapsulating suits is
available at www.personalprotection.dupont.com.
1. If your garment has been contaminated or is suspected
of being contaminated, you must rst undergo eld
decontamination before removing the garment.
2. Continue to use your respirator until the garment has
been doffed and removed.
3. Have an assistant help you doff the garment after
eld decontamination. If the garment has been
contaminated, have your assistant wear appropriate
PPE such as, but not limited to, protective clothing and
gloves and respiratory equipment.
4. While standing, have your assistant open the zipper
aps and then open the zipper.
5. Peel the garment off over your head and down and
away from your shoulders to avoid contaminating your
inner clothing or skin. Have the assistant help you to
remove your arms from the sleeves. If using external
breathing air supply, disconnect external air lines from
the garment while you switch to your escape bottle.
6. Lower the garment to below your hips and sit down.
Disengage waist belt if applicable. Do not touch the
outside of the garment as it may be contaminated. Have
your assistant remove your outer boots, then pull the
garment off of your legs and take the garment away
from the dofng area.
7. Once the garment has been completely removed, you
can doff the respirator face piece and its associated
hardware.
Field Decontamination
The purpose of eld decontamination is to permit the
wearer to remove the garment without being harmed
by contaminants on the outer garment surface. Field
decontamination does not make a garment safe for re-use. If
you suspect or know that a garment has been contaminated,
it must be discarded after eld decontamination.
Decontamination
DuPont™Tychem®garments are designed for limited-use
applications; they can be worn until damaged, altered or
contaminated. If the garment is damaged during use, retreat
immediately, undergo eld decontamination, and then
discard the garment. If the garment is contaminated during
use, it must be discarded after eld decontamination and
dofng.
It is the responsibility of the safety professional to determine
that the suit has not been contaminated and can be safely
re-used.

10
User Manual for DuPont™Tychem®Encapsulated Level A and Encapsulated Level B Suits
Inspection Before Re-use
Thoroughly inspect a used and/or cleaned garment following
the instructions provided in this manual before re-use. Do
not re-use the garment if it fails the inspection or shows
sign of alteration, damage or contamination.
Garment Retirement Considerations
Retire Tychem®garments from service if any of the
following criteria are met:
• Garment fails to pass inspection.
• Level A garment fails the ination test.
• Garment is altered, abraded, cut, torn, punctured, or
otherwise breached.
• Garment has had prolonged exposure to intense heat
and/or ultraviolet light.
• Garment has been contaminated as determined by the
safety professional responsible for having knowledge of
use and exposure conditions.
• Garment has had contact with an oxidative, corrosive or
reactive decontamination agent.
Retired garments that are not contaminated may be labeled
“For Training Use Only”.
Disposal
If not contaminated, Tychem®garments can be disposed of
per local regulations as non-hazardous waste. Garments that
have been contaminated with hazardous materials must be
disposed of as hazardous waste per local regulations after
eld decontamination. Before discarding, mutilate garments
by cutting off a sleeve or a leg so they cannot be worn
again.
Temperature Ranges
Do not store Tychem®garments at temperatures exceeding
120 °F (49 °C).
Tychem®garments can be used in ambient environments
from -13 °F (-25 °C) to 190 °F (88 °C) for short durations.
However, Tychem®garments offer limited thermal insulation
to protect the wearer’s skin from prolonged exposure to
hot or cold temperatures. The usable temperature range for
the materials in the garment can exceed the temperature
at which human skin burn injury may occur. Additionally,
chemical permeation testing is typically performed at 27 °C.
Chemical permeation rates may be affected by temperature.
Limitations of Use
It is the user’s responsibility to determine the level of
exposure and the proper personal protective equipment
needed. Tychem®encapsulated Level A and Level B
garments are not suitable for use in all situations and
environments or with all hazardous materials. All decisions
regarding the selection and use of chemical protective
clothing must be done by trained and qualied safety
professionals.
Do not use Tychem®encapsulated Level A or B garments for
protection against ionizing radiation.
Do not use Tychem®encapsulated Level A or B garments for
protection from cryogenic liquids or gases. A cryogenic liquid
is dened by NFPA 1991 as “a refrigerated liqueed gas
having a boiling point below −90 °C (−130 °F) at atmospheric
pressure”.
If there is a risk of exposure to liqueed gases, then
consider use of a DuPont™Tychem®Level A ensemble which
has been certied to the optional liqueed gas requirements
of NFPA 1991. A liqueed gas is dened by NFPA 1991 as
“a gas that, under its charged pressure, is partially liquid at
