If material is ground, cut, or used in any operation which may generate dusts, use appropriate local exhaust ventilation to
keep exposures below the recommended exposure limits.
The need for ventilation systems should be evaluated by a professional industrial hygienist, while the design of specific
ventilation systems should be conducted by a professional engineer.

Acute and Chronic Toxicity
A: General Product Information
No information available for the product which has not been tested as a whole.
DO NOT MACHINE OR GRIND THIS PRODUCT AS SUPPLIED SINCE SUCH ACTION MAY CAUSE DUST TO BE
GENERATED.
The following information pertains to components of this product which may be available in dusts if this product is subjected
to sanding or grinding or other mechanical processing.
Carbon black acts as a nuisance dust and can interact with disease states or other exposures (smoking, silica) to reduce
pulmonary function or induce fibrosis. Carbon black has been known to weaken the senses of smell and hearing and increase
the metabolic rate.
Chronic inhalation of iron has resulted in mottling of the lungs, a condition referred to as siderosis. This is considered a
benign pneumoconiosis and does not ordinarily cause significant physiologic impairment.
Inhalation of insoluble barium compounds may cause baritosis (a benign pneumoconiosis). Barium sulfate is an insoluble
barium compound.
Chronic overexposure to quartz (the most stable and common form of crystalline silica) is responsible for the majority of
clinically diagnosed silicosis. Silicosis is a fibronodular lung disease that occurs after occupational exposure to crystalline
silica for 5 years or longer. Inhalation of quartz dusts may cause shortness of breath, limitation of chest expansion, dry cough,
and a lessened capacity for work. Individuals with a pre- existing disease in, or a history of ailments involving the skin or
respiratory tract, are at a greater risk of developing adverse health effects when exposed to this material.

Carcinogenicity
A: General Product Information
No information available for the product.
Carbon black produced lung tumors in rats exposed chronically to high concentrations of carbon black by inhalation.
It has been reported that quartz (the most stable and common form of crystalline silica) has caused cancer in animals
subjected to controlled experiments. Epidemiological studies of human diseases have indicated quartz to be a carcinogenic
substance.
Antimony trioxide has been reported to cause cancer in animals subjected to controlled experiments.
