Information on Toxicological effects
Information on likely routes of exposure
Ingestion Possible abdominal obstruction.
Inhalation Dust may irritate respiratory system. Chronic exposure may result in lung disease. (See below)
Skin contact May cause irritation, rash, itching, or dermatitis.
Eye contact Dust may cause mechanical irritation.
Symptoms related to the physical, chemical and toxicological characteristics
Acute exposure to airborne dust concentrations in excess of the PEL/TLV may result in coughing, dyspnea, wheezing, and a
burning irritation of the nose, throat, and upper respiratory tract, along with possible impaired pulmonary function. Chronic
exposures may result in lung disease. (Silicosis and/or lung cancer)

Carcinogenicity Not available
This product contains crystalline silica (quartz) as a naturally occurring impurity in some of the raw materials. The International
Agency for Research on Cancer (IARC) classifies crystalline silica inhaled in the form of quartz or cristobalite from occupational sources
as carcinogenic to humans, Group 1. The National Toxicology Program (NTP) classifies respirable crystalline silica as a substance which
may be reasonably anticipated to be a carcinogen. OSHA does not regulate crystalline silica as a human carcinogen.
Some products may contain attapulgite clay. IARC classifies attapulgite (long fiber) carcinogenic to humans, Group 2B. Attapulgite is
not classified as a carcinogen by NTP or OSHA.
Exposures to respirable crystalline silica are not expected during the recommended use of this product. However, actual levels must
be determined by workplace Industrial Hygiene testing.
