Personal protective equipment Respiratory protection

: Zircon-containing refractory coatings generally contain high levels of particles in the respirable fraction, but the potential for the inhalation of such particles is low when the product is handled in its liquid state. Manage inhalation exposure risks at those operations where dried refractory coatings may be- come airborne, such as spill residue cleanup operations, core touchup operations, shakeout operations, and spent sand handling and processing operations, through exhaust ventila- tion, exposure monitoring and, if needed, through use of res- piratory protection equipment. Respiratory protection is not typically required when ade- quate engineering and other workplace controls and a pro- gram of periodic worker exposure monitoring are provided. Use N100 "HEPA" respirators or supplied air systems where engineering and other workplace controls do not consistently control worker exposures to respirable crystalline silica to

below the OSHA or other applicable exposure criteria. Tight- fitting respirators must be fit-tested either qualitatively or quantitatively for each respirator user. Use only NIOSH- certified respirators. Where respirators are required, a respir- atory protection program shall be implemented in accordance with OSHA Standard 29 CFR §1910.134. ANSI Standard Z88.2 (current edition) "American National Standard for Res- piratory Protection" should also be considered.

Chemical cartridge respirators or supplied air systems are recommended where control of alcohol vapor is required.

Hand protection

Remarks

: Palm-dipped cotton work gloves are recommended for inci- dental contact and general core station use. For tasks involv- ing immersion or similar significant skin exposure use nitrile chemical handling gloves. : Ensure that eyewash stations and safety showers are close to the workstation location. Tightly fitting safety goggles : Personnel working in alcohol-based coating application areas should wear flame-resistant clothing and anti-static footwear. Provide splash and spray protection commensurate with the risks of exposure in your application. Launder work clothing frequently. Change work clothing after each work shift. : Wash hands before breaks and at the end of workday. Exposure monitoring for respirable particulate matter and the product solvent vapor may be warranted depending on the method of application and the amount of exhaust ventilation provided. Maintain respirable dust exposure levels below 2.8 mg/m3 to ensure the internal radiation dose will not exceed 10% of the Annual Limits on Intake (ALI) specified in 10 CFR 20.1502(b) and Nuclear Regulatory Commission (NRC) standards for protection against radiation for thorium, radium, and radioactive daughter decay products. Care should be taken to prevent inhalation exposures at those operations where dried refractory coatings may become airborne, such as spill residue cleanup operations, core touchup operations, shakeout operations, and spent sand handling and pro- cessing operations. Do not breathe over spray in coating spray applications. Zirconium sands and flours contain trace quantities of natu- rally occurring radioactive uranium, thorium and radium. Overexposure by inhalation to respirable dusts may cause lung cancer. Observance of the exposure limits for respirable dust (see Section 8) will ensure that the user is within limits established for exposure to naturally occurring radioactive uranium, thorium and radium.

Quartz (SiO2): General Information

: Breathing silica dust may not cause noticeable injury or illness even though permanent lung damage may be occurring. Inhalation of dust may have serious chronic health effects (see below Repeat Dose Toxicity.) Silicosis: Excessive inhalation of respirable crystalline silica dust may cause a progressive, disabling and sometimes fatal lung disease called silicosis. Symptoms include cough, shortness of breath, wheezing, non-specific chest illness and reduced pulmonary function. This disease is exacerbated by smoking. Inhalation of air with a very high concentration of respirable silica dust can cause the most serious forms of silicosis in a matter of months or a few years. Some epidemiologic studies have concluded that there is significant risk of developing silicosis even at airborne exposure levels that are equal to the recommended NIOSH REL, and ACGIH TLV. Silicosis can exist in several forms, chronic (or ordinary), accelerated, or acute. Chronic Silicosis. Chronic silicosis is the most common presentation of silicosis and usually occurs after at least 10 years of exposure to respirable crystalline silica. Symptoms- shortness of breath and cough, although employees may not notice any symptoms early in the disease. Constitutional symptoms, such as fever, loss of appetite and fatigue, may indicate other diseases associated with silica exposure, such as TB infection or lung cancer. Employees with these symptoms should immediately receive further evaluation and treatment. Accelerated Silicosis. Accelerated silicosis generally occurs within 5-10 years of exposure and results from high levels of exposure to respirable crystalline silica. Symptoms-shortness of breath, cough, and sometimes sputum production. Employees with exposure to respirable crystalline silica, and especially those with accelerated silicosis, are at high risk for activation of TB infections, atypical mycobacterial infections, and fungal superinfections. Constitutional symptoms, such as fever, weight loss, hemoptysis (coughing up blood), and fatigue may herald one of these infections or the onset of lung cancer. Clinical Course-accelerated silicosis has a rapid, severe course. Acute Silicosis. Acute silicosis is a rare disease caused by inhalation of extremely high levels of respirable crystalline silica particles. Acute silicosis develops rapidly, often within a few months to less than 2 years of exposure, and is almost always fatal. Symptoms-sudden, progressive, and severe shortness of breath. Constitutional symptoms are frequently present and include fever, weight loss, fatigue, productive cough, hemoptysis (coughing up blood), and pleuritic chest pain. Employees with acute silicosis are at especially high risk of TB

activation, nontuberculous mycobacterial infections, and fungal superinfections. Acute silicosis is immediately life- threatening. COPD, including chronic bronchitis and emphysema, has been documented in silica-exposed employees, including those who do not develop silicosis. Heart disease may develop secondary to lung diseases such as COPD. A recent study by Liu et al. 2014 noted a significant exposure-response trend between cumulative silica exposure and heart disease deaths, primarily due to pulmonary heart disease, such as cor pulmonale. Renal and Immune System. Silica exposure has been associated with several types of kidney disease, including glomerulonephritis, nephrotic syndrome, and end stage renal disease requiring dialysis. Silica exposure has also been associated with other autoimmune conditions, including progressive systemic sclerosis, systemic lupus erythematosus, and rheumatoid arthritis. Studies note an association between employees with silicosis and serologic markers for autoimmune diseases, including antinuclear antibodies, rheumatoid factor, and immune complexes (Jalloul and Banks 2007; Shtraichman et al. 2015). TB and Other Infections. Silica exposed employees with latent TB are 3 to 30 times more likely to develop active pulmonary TB infection (ATS 1997; Rees and Murray 2007). Although respirable crystalline silica exposure does not cause TB infection, individuals with latent TB infection are at increased risk for activation of disease if they have higher levels of respirable crystalline silica exposure, greater profusion of radiographic abnormalities, or a diagnosis of silicosis. Additionally, silica-exposed employees are at increased risk for contracting nontuberculous mycobacterial infections, including Mycobacterium avium-intracellulare and Mycobacterium kansaii. Lung Cancer. The National Toxicology Program has listed respirable crystalline silica as a known human carcinogen since 2000 (NTP 2014). The International Agency for Research on Cancer (2012) has also classified silica as Group 1 (carcinogenic to humans). Several studies have indicated that the risk of lung cancer from exposure to respirable crystalline silica and smoking is greater than additive (Brown 2009; Liu et al. 2013). Other Data with Possible Relevance to Human Health: There is some evidence that breathing respirable crystalline silica or the disease silicosis is associated with an increased incidence of significant disease endpoints such as scleroderma (an immune system disorder manifested by fibrosis of the lungs, skin and other internal organs) rheumatoid arthritis, systemic lupus, erythematosus, sarcoidosis, chronic bronchitis, chronic obstructive pulmonary disease (COPD), emphysema, chronic kidney disease and end-stage renal disease. Medical Conditions Generally Aggravated by Exposure: The condition of individuals with existing respiratory system disease(s) (e.g., bronchitis, emphysema, chronic obstructive pulmonary disease) and/or dysfunctions can be aggravated by
