Methane <br />Section 8. Exposure controls/personal protection <br />Hand protection <br />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. Respirator selection must be based on known or anticipated exposure <br />levels, the hazards of the product and the safe working limits of the selected respirator. <br />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 />Respiratory protection : <br />: <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. When there is a risk of ignition from static electricity, wear anti- <br />static protective clothing. For the greatest protection from static discharges, clothing <br />should include anti-static overalls, boots and gloves. <br />: <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 />Section 9.
