Use process enclosures, local exhaust <br />ventilation, or other engineering controls to control airborne levels below recommended exposure <br />limits. Use explosion-proof equipment. <br />Individual protection measures, such as personal protective equipment <br />Eye/face protection Wear safety glasses. If splash potential exists, wear full face shield or chemical goggles. <br />Skin protection <br />Hand protection Wear chemical-resistant, impervious gloves. Suitable gloves can be recommended by the glove <br />supplier. Be aware that the liquid may penetrate the gloves. Frequent change is advisable. <br />Other Full body suit and boots are recommended when handling large volumes or in emergency <br />situations. Flame retardant protective clothing is recommended. <br />Respiratory protection Use a properly fitted, air-purifying or air-fed respirator complying with an approved standard if a <br />risk assessment indicates this is necessary. Respirator selection must be based on known or <br />anticipated exposure levels, the hazards of the product and the safe working limits of the selected <br />respirator. If workplace exposure limits for product or components are exceeded, NIOSH approved <br />equipment should be worn. Proper respirator selection should be determined by adequately <br />trained personnel, based on the contaminants, the degree of potential exposure and published <br />respiratory protection factors. This equipment should be available for nonroutine and emergency <br />use. <br />Thermal hazards Wear appropriate thermal protective clothing, when necessary. <br />General hygiene <br />considerations <br />Consult supervisor for special handling instructions. Avoid contact with eyes. Avoid contact with <br />skin. Keep away from food and drink. Wash hands before breaks and immediately after handling <br />the product. Provide eyewash station and safety shower. Handle in accordance with good <br />industrial hygiene and safety practice. <br />9.
