HEALTH HAZARD DATA
PRIMARY
ROUTES OF ENTRY: INHALATION (*) SKIN (*) INGESTION
( )
*During hot processing e.g., extruding, curing,
milling, etc.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
No applicable information available.
ACUTE HEALTH HAZARDS AND EXPOSURE SYMPTOMS:
None known or expected. Ingredients bound
to rubber so inhalation exposure during handling
not a problem. Exposure to volatiles released
during hot processing such as curing may cause
respiratory, nose or eye irritation in some
people.
CHRONIC HEALTH HAZARDS AND EXPOSURE SYMPTOMS:
Long term inhalation exposure to concentrated
hot processing fumes have been reported to
reduce lung function and cause chronic bronchitis.
CARCINOGENICITY: Ethylene Thiourea (ETU) has
been shown to be a carcinogen and teratogen
in experimental animals. Exposure to ETU from
this product is unlikely.
EMERGENCY FIRST AID PROCEDURES
INHALATION: Not expected to be compound-related
effect. Remove to fresh air. If not breathing,
give artificial respiration, preferable mouth-to-mouth.
If breathing difficult, give oxygen. Call
a physician at once.
SKIN: Compound-related effects not expected
to require first aid. If any irritation develops
or persists, see a physician.
INGESTION:
Compound-related effects not expected. If
ingested, treat symptoms.

REACTIVITY DATA
STABLE:
Yes CONDITIONS
TO AVOID: None known.
INCOMPATIBILITY:
No known materials to avoid.
HAZARDOUS DECOMPOSITION PRODUCTS: Typical
products could include carbon monoxide, carbon
dioxide, sulfur oxides and hydrocarbons.
Dimethylnitrosomine
and Nitrosomorpholine See Section 9
HAZARDOUS
POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: None known.
7.
PRECAUTIONS FOR SAFE HANDLING AND USE
STEPS
IN CASE OF SPILL: Pick or sweep up material
and place in suitable container for disposal.
WASTE DISPOSAL METHOD: Dispose of in accordance
with all local, state and federal laws and
regulations.
OTHER: Avoid routine inhalation of hot processing
fumes.
8.
SPECIAL PROTECTION INFORMATION
RESPIRATORY:
Not normally needed for routine handling.
If curing fumes are a problem, a NIOSH approved
air purifying respirator with HEPA filters
may be used. Select and use respirators in
accordance with OSHA 1910.134 and the respirator
manufacturer.
VENTILATION:
Good manufacturing practice demands that inhalation
of fumes and volatiles from further hot processing
of rubber compounds must be avoided. Exhaust
ventilation is usually necessary for operations
which produce fumes, such as extrusion, curing,
etc. Provide effective exhaust ventilation
at all operations capable of producing fumes
to prevent routine inhalation.
OTHER
PROTECTIVE EQUIPMENT: Gloves are needed when
handling hot rubber to prevent burns.
WORK
AND HYGIENE PRACTICES: Maintain good personal
hygiene when working with rubber compounds.
Change soiled clothing regularly. Wash hands
and other exposed skin surfaces thoroughly
at all breaks and at the end of the work shift.
9.
SPECIAL PRECAUTIONS
HANDLING
AND STORAGE: None related to handling and
storage.
OTHER
PRECAUTIONS: A class of materials called nitrosamines
are carcinogens in animals and therefore aresuspected
of causing cancer in humans. Because many
rubber materials contain amine based ingredients,
trace residual amounts (well below 0.1%) of
nitrosamine are likely to exist in most rubber
compounds as a result of being formed in earlier
processing steps.
Subjecting this product to certain processing
steps can form higher amounts of nitrosamines
which are believed to present a health hazard.
Avoid mixing or exposing this product with:
nitrates, nitrites, nitrogen oxides or other
nitrosamines as potentially hazardous levels
of nitrosamines will be formed. Salt bath
curing (using nitrate/nitrite sales) can be
expected to produce hazardous amounts of volatile
nitrosamines. Emissions from such processes
must be exhausted.
Employees must avoid inhaling fumes from hot
rubber processing.

ADDITIONAL
COMMENTS
Caution:
Processing
fumes may cause adverse health effects. Avoid
Inhalation of fumes, use with adequate ventilation.
Maintain good personal hygiene when working
with rubber compounds. Change soiled clothing
regularly. Wash hands and other exposed skin
surface thoroughly at all breaks and at the
end of the work shift. Consult MSDS for additional
and proper handling procedures.
