Form: respirable <br /> fraction <br /> Occupational exposure limits fMexirrol <br /> Ingredient name Exposure limits <br /> Crystalline Silica, respirable powder NOM-0103TPS-2014(Maxim,4/2016). <br /> TWA: 0.025 mg/m'8 hours. Form: <br /> Respirable fraction <br /> Appropriate engineering If user operations generate dust,fumes,gas,vapor or mist, use process enclosures, <br /> controls local exhaust ventilation or other engineering controls to keep worker exposure to <br /> airborne contaminants below any recommended or statutory limits. <br /> Environmental exposure : Emissions from ventilation or work process equipment should be checked to ensure <br /> controls they comply with the requirements of enmronmental protection legislation. In some <br /> cases,fume scrubbers,filters or engineering modifications to the process equipment <br /> will be necessary to reduce emissions to acceptable levels. <br /> Individual protection measures <br /> Hygiene measures Wash hands,forearms and face thoroughly after handling chemical products, before <br /> eating,smoking and using the lavatory and at the end of the working period. <br /> Appropriate techniques should be used to remove potentially contaminated clothing. <br /> Contaminated work clothing should not be allowed out of the workplace. Wash <br /> contaminated clothing before reusing. Ensure that eyewash stations and safety <br /> showers are close to the workstation location. <br /> Eyelface protection Safety eyewear complying with an approved standard should be used when a risk <br /> assessment indicates this is necessary to avoid exposure to liquid splashes,mists, <br /> gases or dusts. If contact is possible,the following protection should be worn,unless <br /> the assessment indicates a higher degree of protection: safety glasses with side- <br /> shields. <br /> Skin protection <br /> Hand protection Chemical-resistant,impervious gloves complying with an approved standard should be <br /> worn at all times when handling chemical products if a risk assessment indicates this is <br /> necessary. Considering the parameters specified by the glove manufacturer,check <br /> during use that the gloves are still retaining their protective properties. It should be <br /> noted that the time to breakthrough for any glove material may be different for different <br /> glove manufacturers. In the case of mixtures, consisting of several substances,the <br /> protection time of the gloves cannot be accurately estimated. <br /> Body protection Personal protective equipment for the body should be selected based on the task being <br /> performed and the risks involved and should be approved by a specialist before <br /> handling this product. <br /> Other skin protection Appropriate footwear and any additional skin protection measures should be selected <br /> based on the task being performed and the risks involved and should be approved by a <br /> specialist before handling this product. <br /> Respiratory protection Based on the hazard and potential for exposure, select a respirator that meets the <br /> appropriate standard or certification. Respirators must be used according to a <br /> respiratory protection program to ensure proper fitting,training, and other important <br /> aspects of use. <br /> Dare oflssue4We ofrsvlslon :992017 Daaedpevbuslssue :4192011 Version :6 9/12 <br />
