SECTION IV - FIRE & EXPLOSION DATA
FLASH POINT (Method Used): 266o F (COC) for DLC product.
FLAMMABLE LIMITS: N/ AUTOIGNITION TEMPERATURE: N/ EXTINGUISHING MEDIA: Dry chemical, water spray (fog), or carbon dioxide.

SPECIAL FIRE FIGHTING PROCEDURES: Standard fire fighting clothing and eye protection should be worn.
Proper respiratory protection should be used to prevent breathing products of combustion and fumes of
allylic compounds if evolved. Use water stream to cool exposed containers.

UNUSUAL FIRE & EXPLOSION HAZARDS: Fumes of allylic compounds may be produced.

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 animals 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.
NATRO-CEL TATM-A NATROCHEM MSDS SECTION V - HEALTH HAZARD DATA (cont)

PRIMARY ROUTE OF ENTRY- Inhalation.

CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN: None.
NTP: No IARC: No OSHA: No

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- Mildly irritating.

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. Inhalation of oil mist or vapors at elevated temperatures may cause respiratory irritation.

INGESTION- Expected to be slightly toxic thru oral ingestion.

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: If swallowed, give two glasses of water.

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) treatment.

HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of carbon and fumes of allylic compounds may
evolve.

HAZARDOUS POLYMERIZATION: Will not occur.
NATRO-CEL TATM-A NATROCHEM MSDS 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.

WASTE DISPOSAL METHOD: Under the CERCLA/RCRA regulations in effect December 29, 1986 this
product is not regulated as a hazardous waste or material. Therefore, it may be disposed of as an industrial
waste management practice and in compliance with applicable 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. Triallyl trimellitate is stable to prolonged storage. UV light or
temperatures greater than 200o F can cause polymerization.

OTHER PRECAUTIONS: Wash with soap and water before eating, drinking, smoking, or using toilet
facilities. Launder contaminated clothing before reuse.
