SECTION V. HEALTH HAZARD DATA
THRESHOLD LIMIT VALUE
(See Section III)
EFFECTS OF OVER EXPOSURE
EYE
Avoid contact with eyes. Slightly to moderately irritating. Abrasive action may cause damage to outer surface of eye.
INHALATION
May cause respiratory tract irritation. Repeated or prolonged breathing of particles of respirable size may cause inflammation of the lung leading to chest pain, difficult breathing, coughing and possible fibrotic change in the lung (Pneumoconiosis). Pre-existing medical conditions may be aggravated by exposure: specifically, bronchial hyper-reactivity and
chronic bronchial or lung disease.
INGESTION
May cause gastrointestinal disturbances. Symptoms may include irritation and nausea, vomiting and diarrhea.
SKIN
Slightly to moderate irritating. May cause irritation and inflammation due to mechanical reaction to sharp, broken ends
of fibers.
EXPOSURE TO USED CERAMIC FIBER PRODUCT
Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial conversion
to cristobalite, a form of crystalline silica which can cause severe respiratory disease (Pneumoconiosis). The amount of
cristobalite present will depend on the temperature and length of time in service. (See Section IX for permissible exposure levels).
SPECIAL TOXIC EFFECTS
The existing toxicology and epidemiology data bases for RCF’s are still preliminary. Information will be updated as
studies are completed and reviewed. The following is a review of the results to date:
EPIDEMIOLOGY
At this time there are no known published reports demonstrating negative health outcomes of workers exposed to refractory ceramic fiber (RCF). Epidemiologic investigations of RCF production workers are ongoing.
1) There is no evidence of any fibrotic lung disease (interstitial fibrosis) whatsoever on x-ray.
2) There is no evidence of any lung disease among those employees exposed to RCF that had never smoked.
3) A statistical “trend” was observed in the exposed population between the duration of exposure to RCF and a de-
crease in some measures of pulmonary function. These observations are clinically insignificant. In other words, if
these observations were made on an individual employee, the results would be interpreted as being within the normal range.

4) Pleural plaques (thickening along the chest wall) have been observed in a small number of employees who had a
long duration of employment. There are several occupational and non-occupational causes for pleural plaque. It
should be noted that plaques are not “pre-cancer” nor are they associated with any measurable effect on lung
function.
TOXICOLOGY
A number of studies on the health effects of inhalation exposure of rats and hamsters are available. Rats were exposed
to RCF in a series of life-time nose-only inhalation studies. The animals were exposed to 30, 16, 9, and 3 mg/m
corresponds with approximately 200, 150, 75, and 25 fibers/cc.
Animals exposed to 30 and 16 mg/m
posed to 9 mg/m
the response typically observed any time a material is inhaled into the deep lung. While a statistically significant increase in lung tumors was observed following exposure to the highest dose, there was no excess lung cancers at the
other doses. Two rats exposed to 30 mg/m
The International Agency for Research on Cancer (IARC) reviewed the carcinogenicity data on man-made vitreous fibers (including ceramic fiber, glasswool, rockwool, and slagwool) in 1987. IARC classified ceramic fiber, fibrous
glasswool and mineral wool (rockwool and slagwool) as possible human carcinogens (Group 2B).

, which
EYE CONTACT
Flush eyes immediately with large amounts of water for approximately 15 minutes. Eye lids should be held away from
the eyeball to insure thorough rinsing. Do not rub eyes. Get medical attention if irritation persists.
INHALATION
Remove person from source of exposure and move to fresh air. Some people may be sensitive to fiber induced irritation
of the respiratory tract. If symptoms such as shortness of breath, coughing, wheezing or chest pain develop, seek medical attention. If person experiences continued breathing difficulties, administer oxygen until medical assistance can be
rendered.
INGESTION
Do not induce vomiting. Get medical attention if irritation persists.
SKIN CONTACT
Do not rub or scratch exposed skin. Wash area of contact thoroughly with soap and water. Using a skin cream or lotion
after washing may be helpful. Get medical attention if irritation persists.

SECTION VII. SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED
Where possible, use vacuum suction with HEPA filters to clean up spilled material. Use dust suppressant where sweeping if necessary. Avoid clean up procedure which may result in water pollution. (Observe Special Protection Information Section VIII.)
WASTE DISPOSAL METHODS
The transportation, treatment, and disposal of this waste material must be conducted in compliance with all applicable
Federal, State, and Local regulations.
SECTION VIII. SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION
Use NIOSH or MSHA approved equipment when airborne exposure limits may be exceeded. NIOSH/MSHA approved
breathing equipment may be required for non-routine and emergency use. (See Section IX for suitable equipment).
Pending the results of long term health effects studies, engineering control of airborne fibers to the lowest levels attainable is advised.
VENTILATION
Ventilation should be used whenever possible to control or reduce airborne concentrations of fiber and dust. Carbon
monoxide, carbon dioxide, oxides of nitrogen, reactive hydrocarbons and a small amount of formaldehyde may accompany binder burn-off during first heat. Use adequate ventilation or other precautions to eliminate vapors resulting from
binder burn-off. Exposure to burn-off fumes may cause respiratory tract irritation, bronchial hyper-reactivity and asthmatic response.
SKIN PROTECTION
Wear gloves, hats and full body clothing to prevent skin contact. Use separate lockers for work clothes to prevent fiber
transfer to street clothes. Wash work clothes separately from other clothing and rinse washing machine thoroughly after
use.
EYE PROTECTION
Wear safety glasses or chemical worker’s goggles to prevent eye contact. Do not wear contact lenses when working
with this substance. Have eye baths readily available where eye contact can occur.

SECTION IX. SPECIAL PRECAUTIONS
PRECAUTIONS TO BE TAKEN IN HANDLING AND STORING
General cleanliness should be followed.
The Toxicology data indicate that ceramic fiber should be handled with caution. The handling practices described in this
MSDS must be strictly followed. In particular, when handling refractory ceramic fiber in any application, special caution should be taken to avoid unnecessary cutting and tearing of the material to minimize generation of airborne dust.
It is recommended that full body clothing be worn to reduce the potential for skin irritation. Washable or disposable
clothing may be used. Do not take unwashed work clothing home. Work clothes should be washed separately from
other clothing. Rinse washing machine thoroughly after use. If clothing is to be laundered by someone else, inform
launderer of proper procedure. Work clothes and street clothes should be kept separate to prevent contamination.
Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial conversion
to cristobalite, a form of crystalline silica. This reaction occurs at the furnace lining hot face. As a consequence, this
material becomes more friable; special caution must be taken to minimize generation of airborne dust. The amount of
cristobalite present will depend on the temperature and length in service.
IARC has recently reviewed the animal, human, and other relevant experimental data on silica in order to critically
evaluate and classify the cancer causing potential. Based on its review, IARC classified crystalline silica as a group 2A
carcinogen (probable human carcinogen).
The OSHA permissible exposure limit (PEL for cristobalite is 0.05 mg/m
value (TLV) for cristobalite is 0.05 mg/m
ment when airborne exposure limits may be exceeded. The minimum respiratory protection recommended for given airborne fiber or cristobalite concentrations are:

Insulation surface should be lightly sprayed with water before removal to suppress airborne dust. As water evaporates
during removal, additional water should be sprayed on surfaces as needed. Only enough water should be sprayed to
suppress dust so that water does not run onto the floor of the work area. To aid the wetting process, a surfactant can be
used.
After RCF removal is completed, dust-suppressing cleaning methods, such as wet sweeping or vacuuming, should be
used to clean the work area. If dry vacuuming is used, the vacuum must be equipped with HEPA filter. Air blowing or
dry sweeping should not be used. Dust-suppressing components can be used to clean up light dust.
Product packaging may contain product residue. Do not reuse except to reship or return Ceramic Fiber products to the

SECTION 1
1-1 COMPONENT CHECKLIST OF TYPICAL
SYSTEM (PACKAGE CONTENTS)
A typical Rosemount Hazardous Area Oxymitter
DR In-Situ Oxygen Probe should contain the
items shown in Figure 1-1. Record the part number, serial number, and order number for each
component of your system in the table located on
the back cover of this manual.
The Oxymitter DR is offered in both
hazardous and general purpose configurations. The hazardous area version has the “EX” and CSA symbols
on the apparatus approval label. The
general purpose version does not
have an approval label. If you received
the general purpose version, ensure
you do not install it in a potentially explosive atmosphere.
Also, use the product matrix in Table 1-1 at the
end of this section to compare your order number against your unit. The first part of the matrix
defines the model. The last part defines the
various options and features of the Hazardous
Area Oxymitter DR. Ensure the features and
options specified by your order number are on
or included with the unit.
b. System Description
The Hazardous Area Oxymitter DR is designed to measure the net concentration of
oxygen in an industrial combustion process;
i.e., the oxygen remaining after all fuels have
been oxidized. The probe is permanently positioned within an exhaust duct or stack and
performs its task without the use of a sampling system.
The equipment measures oxygen percentage by reading the voltage developed across
a heated electrochemical cell, which consists
of a small yttria-stabilized, zirconia disc. Both
sides of the disc are coated with porous
metal electrodes. When operated at the
proper temperature, the millivolt output voltage of the cell is given by the following
Nernst equation:
EMF = KT log
Where:
1. P
is the partial pressure of the
2
oxygen in the measured gas on
one side of the cell.
2. P
is the partial pressure of the
1
oxygen in the reference air on
the opposite side of the cell.
3. T is the absolute temperature.

1-2 SYSTEM OVERVIEW
a. Scope
This Instruction Bulletin is designed to supply
details needed to install, start up, operate,
and maintain the Hazardous Area Oxymitter
DR. The Hazardous Area Direct Replacement Oxymitter can be interfaced to a number of different earlier model electronics
packages. These electronic packages are
not covered in this manual. For specification
information concerning calibration and operation of the system, refer to the Instruction
Bulletin applicable to your electronics.
Rosemount Analytical Inc. A Division of Emerson Process Management Description and Specifications 1-1
4. C is the cell constant.
5. K is an arithmetic constant.
When the cell is at operating temperature
and there are unequal oxygen concentrations across the cell, oxygen ions will travel
from the high oxygen partial pressure side to
the low oxygen partial pressure side of the
cell. The resulting logarithmic output voltage
is approximately 50 mV per decade. The
output is proportional to the inverse logarithm
of the oxygen concentration. Therefore, the
output signal increases as the oxygen concentration of the sample gas decreases. This
characteristic enables the Hazardous Area
Oxymitter DR to provide exceptional sensitivity at low oxygen concentrations.
Instruction Manual
IB-106-340CDR Original Issue
January, 2002
Hazardous Area Oxymitter DR
The Hazardous Area Oxymitter DR measures net oxygen concentration in the presence of all the products of combustion,
including water vapor. Therefore, it may be
considered an analysis on a “wet” basis. In
comparison with older methods, such as the
portable apparatus, which provides an
analysis on a “dry” gas basis, the “wet”
analysis will, in general, indicate a lower percentage of oxygen. The difference will be
proportional to the water content of the sampled gas stream.
c. System Configuration
Hazardous Area Oxymitter DR units are
available in three length options, giving the
user the flexibility to use an in situ penetration appropriate to the size of the stack or
duct. The options on length are 457 mm
(18 in.), 0.91 m (3 ft), 1.83 m (6 ft).
Abrasive shields are offered for applications
where abrasive particulates are present.
Acid resistant cells are available for SO
2
and HCl environments. Bypass and probe
mounting jacket options are available for
process temperatures above 1300°F
(705°C).
d. System Features
1. The cell output voltage and sensitivity
increase as the oxygen concentration
decreases.
2. Field replaceable cell, heater, thermocouple, and diffusion element.
3. The Hazardous Area Oxymitter DR is
constructed of rugged 316L stainless
steel for all wetted parts.

to shock when mishandled.
f. System Considerations
Prior to installing your Hazardous Area
Oxymitter DR, make sure you have all the
components necessary to make the system
installation. Ensure all the components are
properly integrated to make the system
functional.
NOTE
Retain the packaging in which the
Hazardous Area Oxymitter DR arrived
from the factory in case any components are to be shipped to another
site. This packaging has been designed to protect the product.
After verifying that you have all the components, select mounting locations and determine how each component will be placed in
terms of available line voltage, ambient
temperatures, environmental considerations, convenience, and serviceability. A
typical system installation is illustrated in
Figure 1-2.
Instrument air for reference is optional for
most applications. Ambient air will passively
diffuse into the inside of the probe in sufficient quantity for an accurate measurement.
Instrument air is required for applications
where the ambient air at the probe location
may not contain the typical 20.95% O
example would be an installation into a
positive pressure flue gas duct which has
many leaks into the surrounding air.
If the calibration gas bottles will be permanently connected, a blocking valve or check
valve is required next to the calibration fittings on the termination housing.

This check valve or blocking valve is to
prevent breathing of the calibration gas line
and subsequent flue gas condensation and
corrosion.
g. Upgrading the Hazardous Area
Oxymitter DR
The Hazardous Area Oxymitter DR can
be easily upgraded to a full Oxymitter
4000 or 5000. This provides an economical upgrade path for users looking to preserve their probe investment upon the
eventual failure of the signal conditioning
electronics. Upgrading the Hazardous
Area Oxymitter DR to a full Oxymitter
4000 or 5000 requires only the addition of
a small electronics package to the existing termination housing of the Hazardous
Area Oxymitter DR probe. The converted
unit will be a full Oxymitter 4000 or 5000
Oxygen Transmitter with the capability of
providing a 4-20 mA oxygen signal without the need for an external signal conditioning electronics package. HART or
Fieldbus communications are provided
with the Oxymitter electronics. See Appendix A for upgrade information.

tures from igniting unburned fuel in the
stack. The ceramic diffusion assembly is
also available with a dust seal for use with
the abrasive shield assembly.
c. Flame Arrestor Snubber Diffusion
Assembly
The snubber diffusion assembly, Figure 14, is satisfactory for most applications.
This element is also available with a dust
seal for use with an abrasive shield.
The abrasive shield assembly, Figure 1-5,
is a stainless-steel tube that surrounds
the probe assembly. The shield protects
against particle abrasion and condensations, provides a guide for ease of
insertion, and acts as a position support,
especially for longer probes. The abrasive
shield assembly uses a modified diffusor
and vee deflector assembly, fitted with
dual dust seal packing.
b. Flame Arrestor Ceramic Diffusion
Assembly
The flame arrestor ceramic diffusion assembly, Figure 1-3, includes a set of baffles between the cell and the stack gases.

INSTALLATION
The Hazardous Area Oxymitter DR and
probe abrasive shield are heavy. Use
proper lifting and carrying procedures
to avoid personal injury.
Instruction Manual
IB-106-340CDR Original Issue
January, 2002
SECTION 2
4. The sensing point should be selected
so the process gas temperature falls
within a range of 0° to 704°C (32° to
1300°F). Figure 2-1 through Figure 2-4
provide mechanical installation references. The ambient temperature of the
termination housing must not exceed
65°C (149°F).
Before installing this equipment, read
the “Safety instructions for the wiring
and installation of this apparatus” at
the front of this Instruction Bulletin.
Failure to follow safety instructions
could result in serious injury or death.
2-1 MECHANICAL INSTALLATION
If the probe will be installed into an existing location, proceed to paragraph 2-1b.
a. Selecting Location
1. The location of the Hazardous Area
Oxymitter DR in the stack or flue is
most important for maximum accuracy
in the oxygen analyzing process. The
Hazardous Area Oxymitter DR must be
positioned so the gas it measures is
representative of the process. Best results are normally obtained if the Hazardous Area Oxymitter DR is
positioned near the center of the duct
(40-60% insertion).
5. Ducts and stacks that operate under
negative pressure will draw air in
through any holes or torn seals, substantially affecting the oxygen reading.
Therefore, either make the necessary
repairs or install the Hazardous Area
Oxymitter DR upstream of any leakage.
6. Ensure the area is clear of internal and
external obstructions that will interfere
with installation and maintenance. Allow adequate clearance for removal of
the Hazardous Area Oxymitter DR
(Figure 2-1).
b. Installation
1. Ensure all components are available to
install the Hazardous Area Oxymitter
DR. If equipped with the optional ceramic diffusion element, ensure it is not
damaged.
2. The Hazardous Area Oxymitter DR
may be installed intact as it is received.
2. Longer ducts may require several Hazardous Area Oxymitter DR units since
the O
can vary due to stratification.
2
3. A point too near the wall of the duct, or
the inside radius of a bend, may not
provide a representative sample because of the very low flow conditions.
Rosemount Analytical Inc. A Division of Emerson Process Management Installation 2-1
An abrasive shield is recommended
for high velocity particulate in the flue
stream (such as those in coal-fired
boilers, kilns, and recovery boilers).
3. Weld or bolt adapter plate (Figure 2-4)
onto the duct.

4. If using the optional ceramic diffusion
element, the vee deflector must be correctly oriented. Before inserting the
Hazardous Area Oxymitter DR, check
the direction of gas flow in the duct. Orient the vee deflector so the apex points
upstream toward the flow (Figure 2-5).
This may be done by loosening the
setscrews and rotating the vee deflector
to the desired position. Retighten the
setscrews.
5. In vertical installations, ensure the system cable drops vertically from the Hazardous Area Oxymitter DR and the
conduit is routed below the level of the
termination housing. This drip loop
minimizes the possibility that moisture
will damage the electrical connections
(Figure 2-6).

Disconnect and lock out power before
connecting the unit to the power
supply.
NOTE
If process temperatures will exceed
200°C (392°F), use anti-seize compound on stud threads to ease future
removal of Oxymitter DR.
7. Insert probe through the opening in the
mounting flange and bolt the unit to the
flange.
NOTE
To maintain CE compliance, ensure a
good connection exists between the
mounting plate studs or earthing
screws on termination housing and
earth.
8. Ensure the Hazardous Area Oxymitter
DR is properly earthed by way of both
internal and external points.
9. If insulation is being removed to access
the duct work for Hazardous Area
Oxymitter DR mounting, make sure the
insulation is replaced afterward (Figure
2-6).
Install all protective equipment covers
and safety ground leads after installation. Failure to install covers and
ground leads could result in serious
injury or death.
To meet the Safety Requirements of
IEC 1010 (EC requirement), and ensure
safe operation of this equipment, connection to the main electrical power
supply must be made through a circuit
breaker (min 10 A) which will disconnect all current-carrying conductors
during a fault situation. This circuit
breaker should also include a mechanically operated isolating switch. If
not, then another external means of
disconnecting the supply from the
equipment should be located close by.
Circuit breakers or switches must
comply with a recognized standard
such as IEC 947.
10. Ensure the installation does not obscure
the messages on either housing cover.

NOTE
The voltage given above is for an ambient (machinery space) temperature
of 25°C (77°F). For each degree of ambient temperature above or below 25°C
(77°F), add or subtract 0.242 mV from
the nominal. Example: at 31°C (87°F),
the nominal voltage of -322.3 Mv
should be increased (made less negative) by 10 x 0.242 or 2.42 mV, making
the adjusted nominal -319.9 Mv.

Figure 4-4. Cell Replacement Kit
Use heat-resistant gloves and clothing
when removing the probe. Do not attempt to work on these components
until they have cooled to room temperature. Probe components can be as
hot as 427°C (800°F). This can cause
severe burns.
Disconnect and lock out power before
working on any electrical components.
There is voltage of up to 115 VAC.
Do not remove the cell unless certain
it needs to be replaced. Removal may
damage the cell and platinum pad. Go
through the complete troubleshooting
procedure to make sure the cell needs
to be replaced before removing it.
a. Follow the instructions in paragraph 4-3a to
remove the Hazardous Area Oxymitter DR
from the stack or duct.
c. If equipped with the optional ceramic diffu-
sion assembly, remove and discard the
setscrews and remove the vee deflector
(Figure 4-5). Use spanner wrenches from
the probe disassembly kit (Table 7-1), to
turn the hub free from the retainer. Inspect
the diffusion element. If damaged, replace
the element.
d. Loosen the four socket head cap screws
from the cell and flange assembly and remove the assembly and the corrugated
seal. The cell flange has a notch that may
be used to gently pry the flange away from
the probe. Note that the contact pad inside
of the probe will sometimes fuse to the oxygen sensing cell. If the cell is fused to the
contact pad, push the cell assembly back
into the probe (against spring pressure) and
quickly twist the cell assembly. The cell and
contact pad should separate. If the contact
pad stays fused to the cell, a new
contact/thermocouple assembly must be installed. Disconnect the cell and the thermocouple wires at the probe electronics and
withdraw the cell with the wires still
attached.
e. Remove four screws (15, Figure 4-1) and
washers (14).
f. Separate the electrical connectors between
the heater strut and the termination housing.

l. Apply anti-seize compound to the threads of
the cell assembly, hub, and setscrews. Reinstall the hub on the cell assembly. Using
pin spanner wrenches, torque to 14 N·m
(10 ft-lbs). If applicable, reinstall the vee deflector, orienting apex toward gas flow. Secure with the setscrews and anti-seize
compound. Torque to 2.8 N·m (25 in-lbs).
Set reference air flow at 56.6 l/hr (2 scfh).
After the Hazardous Area Oxymitter DR stabilizes, calibrate the unit. If new components
have been installed, repeat calibration after
24 hours of operation.
4-8 CERAMIC DIFFUSION ELEMENT
REPLACEMENT
NOTE
This refers to the ceramic diffusion
element only.
a. General
The diffusion element protects the cell from
particles in process gases. Normally, it does
not need to be replaced because the vee
deflector protects it from particulate erosion.
In severe environments, the filter may be
broken or subject to excessive erosion. Examine the ceramic diffusion element whenever removing the probe for any purpose.
Replace if damaged.
Damage to the ceramic diffusion element
may become apparent during calibration.
Compare probe response with previous response. A broken diffusion element will
cause a slower response to calibration gas.
Hex wrenches needed to remove setscrews
and socket head screws in the following
procedure are available as part of a Probe
Disassembly Kit, Table 7-1.
m. On systems equipped with an abrasive
shield, install the dust seal gaskets, with
joints 180° apart.
n. Reinstall the probe and gasket on the stack
flange.
o. Follow the instructions in paragraph 4-3b to
install the Hazardous Area Oxymitter DR
into the stack or duct. If there is an abrasive
shield in the stack, make sure the dust seal
gaskets are in place as they enter the 15°
reducing cone.
p. Turn on power and monitor thermocouple
output. It should stabilize at 29.3+0.2 mV.
Rosemount Analytical Inc. A Division of Emerson Process Management Maintenance and Service 4-7
b. Replacement Procedure
1. Follow the instructions in paragraph
4-3a to remove the Hazardous Area
Oxymitter DR from the stack or duct.
2. Loosen setscrews, Figure 4-5, using
hex wrench from Probe Disassembly
Kit, Table 7-1, and remove vee deflector. Inspect setscrews. If damaged, replace with stainless setscrews coated
with anti-seize compound.

Do not get cement on ceramic diffusion element except where it touches
the hub. Any cement on ceramic diffusion element blocks airflow through
element. Wiping wet cement off of ceramic only forces cement into pores.
Also, do not get any cement onto the
flame arrestor element.
9. Thoroughly mix cement and insert tip
of squeeze bottle into cement port. Tilt
bottle and squeeze while simultaneously turning ceramic diffusion element
into seat. Do not get any cement on
upper part of ceramic diffusion element. Ensure complete penetration of
cement around 3 grooves in hub. Cement should extrude from opposite
hole. Wipe excess material back into
holes and wipe top fillet of cement to
form a uniform fillet. (A cotton swab is
useful for this.) Clean any excess cement from hub with water.
10. Allow filter to dry at room temperature
overnight or 1 to 2 hours at 93°C
(200°F).
11. Wipe a heavy layer of anti-seize compound onto the threads and mating
surfaces of the flame arrestor, diffusion
hub, and probe tube.
6. Break out remaining ceramic diffusion
element by tapping lightly around hub
with hammer. Clean grooves with
pointed tool if necessary.
7. Replace ceramic diffusion element using the ceramic diffusion element replacement kit in Table 7-1. This
consists of a diffusion element, cement, setscrews, anti-seize compound,
and instructions.
8. Test fit replacement ceramic diffusion
element to be sure seat is clean.
