Section 8. Exposure controls/personal protection <br />Eye/face 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 <br />is 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 <br />being performed and the risks involved and should be approved by a specialist before <br />handling this product. When there is a risk of ignition from static electricity, wear <br />antistatic protective clothing. For the greatest protect ion from static discharges, <br />clothing should include anti-static overalls, boots and gloves. <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 <br />a specialist before handling this product. <br />Respiratory protection : Use a properly fitted, air-purifying or air-fed respirator complying with an approved <br />standard if a risk assessment indicates this is necessary. Respirator s election must be <br />based on known or anticipated exposure levels, the hazards of the product and the <br />safe working limits of the selected respirator. <br />Section 9.
