HAZARDS IDENTIFICATIONRisk PhrasesNoneHazard OverviewCAUTION!

2 - ACUTE HEALTH HAZARD May cause eye and respiratory irritation. DANGER! - CHRONIC HEALTH HAZARD Breathing crystalline silica can cause lung disease, including silicosis and lungcancer. Crystalline silica has also been associated with scleroderma and kidneydisease. This product contains quartz, cristobalite, and/or tridymite which may becomeairborne without a visible cloud. Avoid breathing dust. Avoid creating dustyconditions. Use only with adequate ventilation to keep exposures belowrecommended exposure limits. Wear a NIOSH certified, European Standard EN149, or equivalent respirator when using this product. Review the Material SafetyData Sheet (MSDS) for this product, which has been provided to your employer.

9 Additional GuidelinesNot Applicable 11. TOXICOLOGICAL INFORMATIONP rinciple Route of ExposureEye or skin contact, inhalation. InhalationInhaled crystalline silica in the form of quartz or cristobalite from occupationalsources is carcinogenic to humans (IARC, Group 1). There is sufficient evidence inexperimental animals for the carcinogenicity of tridymite (IARC, Group 2A).Breathing silica dust may cause irritation of the nose, throat, and respiratorypassages. Breathing silica dust may not cause noticeable injury or illness eventhough permanent lung damage may be occurring. Inhalation of dust may also haveserious chronic health effects (See Chronic Effects/Carcinogenicity" subsectionbelow).

10 " Skin ContactMay cause mechanical injury. Eye ContactMay cause eye irritation. IngestionNone known Aggravated Medical ConditionsIndividuals with respiratory disease, including but not limited to asthma andbronchitis, or subject to eye irritation, should not be exposed to quartz dust. Chronic Effects/CarcinogenicitySilicosis: Excessive inhalation of respirable crystalline silica dust may cause aprogressive, disabling, and sometimes-fatal lung disease called silicosis. Symptomsinclude cough, shortness of breath, wheezing, non-specific chest illness, andreduced pulmonary function. This disease is exacerbated by smoking.
