FIRE AND EXPLOSION HAZARDS: .. During a fire, smoke may contain the original materials in addition to
combustion products of varying composition which may be toxic and/or irritating. Combustion products may include, but are not limited to: oxides
of nitrogen, carbon monoxiie, iarbon dioxide, volatile amines, ammonia, nitric acid, aldehydes, nihosamines. When mixed with sawdust, wood
chips, Jr other cellulosic material, spontaneous combustion can occur under certain conditions. Heat is generated as the air oxidizes the amine. lf
the heat is not dissipated quickly enough, it can ignite the sawdust.
SpECIAL FIRE FIGHTING PROCEDURES:………………….. Use full-body protective gear and a self-contained breathing apparatus.
Use of water may generate toxic aqueous solutions. Do not allow water run-off from fighting fire to enter drains or other water courses’
EMERGENCY MEASURES: Keep unnecessary and unprotected personnel from entering area. Use

HANDLING PRECAUTIONS Use with adequate ventilation. Do not breathe vapors or mists from heated
material. Do not breathe concentrated vapors. Avoid all skin and eye contact. Wash thoroughly after handling. When mixed with epoxy resin this
product causes an exothermic reaction, which in large masses, can produce enough heat to damage or ignite surrounding materials and emit
fumes and vapors that vary widely in composition and toxicity.
ENGINEERING CONTROLS:.. …Use with adequate general ventilation and/or local ventilation to keep
exposures below established limits
EYE PROTECTION GUIDELINES: Chemical splash-proof goggles or face shield.
Wear liquid-proof, chemical resistant gloves (nitrile-butyl rubber, neoprene
butyl rubber or natural rubber) and full body-covering clothing
RESPIRATORY PROTECTION GUIDELINES: When ventilation cannot be made adequate enough to keep exposures
below established limits, use a NIOSH approved respirator with an organic vapor cartridge, organic vapor cartridge + P100, or a multi-contaminant
cartridge, depending on specific workplace conditions. Consult with your respirator and cartridge supplier to ensure proper selection of respirator
and cartridge based on ingredients listed in Section 3 and specific workplace conditions. Use and select a respirator according the guidelines
established in OSHA 1910.134 or other applicable respiratory protection standard.
ADDITIONAL PROTECTIVE MEASURES : Use where there is immediate access to safety shower and emergency eye
wash. Wash thoroughly afier use. Contact lens should not be worn when working with this material. Generally speaking, working cleanly and
following basic precautionary measures will greatly minimize the potential for harmful exposure to this product under normal use conditions.

Product:
Remarks : Titanium dioxide (13463-67-7)
In lifetime inhalation studies of rats, airborne respirable-size
titanium dioxide particles have shown to cause an increase in
lung tumors at concentrations associated with substantial
particle lung burdens and consequential pulmonary overload
and inflammation. The potential for these adverse health ef-
fects appears to be closely related to the particle size and the
amount of the exposed surface area that comes into contact
with the lung. However, tests with other laboratory animals
such as mice and hamsters, indicate that rats are significantly
more susceptible to the pulmonary overload and inflammation
that causes lung cancer. Epidemiological studies do not sug-
gest an increased risk of cancer in humans from occupational
exposure to titanium dioxide. Titanium dioxide has been char-
acterized by IARC as possibly carcinogenic to humans (Group
2B) through inhalation (not ingestion). It has not been charac-
terized as a potential carcino
gen by either NTP or OSHA.
Quartz (14808-60-7): This classification is relevant when ex-
posed to Quartz (silicon dioxide) in dust or powder form only,
including cured product that is subject to sanding, grinding,
cutting, or other surface preparation activities.
