Local <br /> exhaust ventilation should be used at points where dust, mist, vapors or <br /> gases can escape into the room air. Adequate ventilation should be <br /> provided so that exposure limits are not exceeded . <br /> Individual protection measures , such as personal protective equipment <br /> General information : Use explosion-proof ventilation equipment. Provide easy access to water <br /> supply and eye wash facilities . Good general ventilation (typically 10 air <br /> changes per hour) should be used . Ventilation rates should be matched to <br /> conditions . If applicable , use process enclosures , local exhaust ventilation , <br /> or other engineering controls to maintain airborne levels below <br /> recommended exposure limits . If exposure limits have not been <br /> established , maintain airborne levels to an acceptable level . Good general <br /> ventilation (typically 10 air changes per hour) should be used . Ventilation <br /> rates should be matched to conditions . Supplementary local exhaust <br /> ventilation , closed systems , or respiratory and eye protection may be <br /> needed in special circumstances , such as poorly ventilated spaces , <br /> heating , evaporation of liquids from large surfaces , spraying of mists , <br /> mechanical generation of dusts , drying of solids , etc . <br /> SDS US - ULTRAZOL® GA9058 7/ 19 <br />
