 Occupational exposure          : Use process enclosures, local exhaust ventilation, or other engineering controls to 
 controls                         keep airborne levels below recommended exposure limits. If user operations 
                                  generate dust, fume or mist, use ventilation to keep exposure to airborne 
                                  contaminants below the exposure limit. 
 Respiratory protection         : Use a properly fitted, particulate filter respirator complying with an approved standard 
                                  if a risk assessment indicates this is necessary.Respirator selection must be based on 
                                  known or anticipated exposure levels, the hazards of the product and the safe working 
                                  limits of the selected respirator. 
 Hand protection                : Chemical-resistant, impervious gloves or gauntlets complying with an approved 
                                  standard should be worn at all times when handling chemical products if a risk 
                                  assessment indicates this is necessary. 
 Eye protection                 : Safety eyewear complying with an approved standard should be used when a risk 
                                  assessment indicates this is necessary to avoid exposure to liquid splashes, mists or 
                                  dusts. 
 Skin protection                : Personal protective equipment for the body should be selected based on the task 
                                  being performed and the risks involved and should be approved by a specialist before 
                                  handling this product.
