Ventilation rates should be matched toconditions. If applicable, use process enclosures, localexhaust ventilation, or other engineering controls to maintainairborne levels below recommended exposure limits. Ifexposure limits have not been established, maintain airbornelevels to an acceptable level.Personal protective equipmentRespiratory protection: Use a properly fitted, particulate filter respirator complyingwith an approved standard if a risk assessment indicates this3 / 14
