NATRO-CEL 200 A-65 NATROCHEM MSDS SECTION V - HEALTH HAZARD DATA
CHRONIC HEALTH EFFECTS: An epidemiological study was conducted which included 165 precipitated silica
workers who had been exposed for an average of 18 years. No adverse effects were noted in complete medical
examination (including chest roentgenograms) of these workers. Pulmonary function decrements were correlated
only with smoking and age but not with the degree or duration of dust exposure. Laboratory studies have also
been conducted in small animals via inhalation to levels of precipitated silica dust of up to 126 mg/m3 for periods
from six months to two years. Although precipitated silica was temporarily deposited in the animal??s lungs, most
of the deposited material was cleared soon after the dust exposure ended. The results of all studies performed
by, or known to, PPG indicate a very low order of pulmonary activity for synthetic precipitated silica.
PRIMARY ROUTE OF ENTRY- Inhalation, skin contact.
CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN: None.
NTP: No IARC: No OSHA: No
There are no known chronic effects of Natro-Cel 200 A-65. Natrochem, Inc. Does not expect
occupational exposure to o-toluidine to occur during use of this material; however, the following is given for your
information. From a recent human epidemiological study, NIOSH has concluded that workers exposed to aniline
and o-toluidine may be at increased risk for developing bladder cancer. IARC has determined that previous
human studies are insufficient to determine if o-toluidine has the potential to cause cancer. IARC concluded that
in experimental animals o-toluidine hydrochloride is a potential carcinogen. NTP states that o-toluidine may
reasonably be anticipated to be a carcinogen.
EFFECTS OF EXPOSURE-
EYES- Mildly irritating. Excessive contact with powder can cause drying of mucous membranes of eyes due to
absorption of moisture and oils.
SKIN- Long term skin contact with this material can cause skin irritation.
INHALATION- Nuisance dust. Excessive contact with powder can cause drying of mucous membranes of nose
and throat due to absorption of moisture and oils. This material can also cause nasal irritation and nosebleeds.
Long-term inhalation of vapors may cause respiratory tract irritation.
INGESTION- Not significantly toxic.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE- Persons with breathing problems or lung disease
should not work in dusty areas unless a physician approves and certifies their fitness to wear respiratory
protection.
SECTION VI - EMERGENCY & FIRST AID PROCEDURES
EYE CONTACT: Immediately rinse with clean water for 15 minutes. Retract eyelids often. If irritation persists,
seek medical attention.
SKIN CONTACT: Immediately remove contaminated clothing. Wash skin thoroughly with mild soap and water.
Flush with lukewarm water for 15 minutes. Seek medical attention if ill effect or irritation develops.
INHALATION: If overcome by exposure, remove victim to fresh air.
INGESTION: Induce vomiting, seek medical attention.
NATRO-CEL 200 A-65 NATROCHEM MSDS SECTION VII - REACTIVITY DATA
STABILITY: Stable.
MATERIALS TO AVOID- Avoid alteration of product properties before reuse. Calcining, which may result in
crystalline formation or mixing with additives may alter toxicological properties.
CONDITIONS TO AVOID- Avoid high temperatures (>800o C).
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of carbon when burned.
HAZARDOUS POLYMERIZATION: Will not occur.
SECTION VIII - SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: MINIMIZE SPILL AREA. Vacuum
spill material and place in closed plastic bags for disposal. Avoid skin contact.
WASTE DISPOSAL METHOD: In accordance with local, state, and federal regulations.
SECTION IX - SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION: Use a respirator such as 3M 9900 or equivalent for protection against
pneumoconiosis producing dusts.
VENTILATION: Provide explosion proof ventilation as required to control airborne dust levels. The sum total of
all ingredients may emit vapors during normal processing. All possible health effects are not known and individual
sensitivities will vary. Effective exhaust ventilation should always be provided to draw dust, fumes and vapors
away from workers to prevent routine inhalation. Ventilation should be adequate to maintain ambient workplace
atmosphere below the limits listed in Section V.
PROTECTIVE GLOVES: Impervious gloves to protect against contact with product.
EYE PROTECTION: Safety goggles.
OTHER PROTECTIVE EQUIPMENT: Protective clothing, eye wash station, safety shower.
SECTION X - SPECIAL PRECAUTIONS
HANDLING AND STORAGE: Handling can create explosive dust clouds. Eliminate ignition sources, use
explosive proof equipment. Conveying and processing equipment should be spark-proof, well bonded and
grounded. Avoid dust accumulations.
OTHER PRECAUTIONS: Wash with soap and water before eating, drinking, smoking, or using toilet facilities.
Launder contaminated clothing before reuse.
