8 However, becauseof the physical nature of this product, dust generation is not engineeringcontrolsIf material is ground, cut, or used in any operation which may generate dusts, use appropriate localexhaust ventilation to keep exposures below the recommended exposure limits. If engineeringmeasures are not sufficient to maintain concentrations of dust particulates below the OEL, suitablerespiratory protection must be protection measures, such as personal protective equipmentEye/face protectionEye wash fountain is recommended. Wear SAFETY glasses; chemical goggles for fumes which mayarise from thermal protectionFor prolonged or repeated skin contact use suitable protective material is heated, wear gloves to protect against thermal protectionWhen workers are facing concentrations above the exposure limit they must use appropriatecertified respirators.
