US. NIOSH: Pocket Guide to Chemical Hazards <br />Components Type Value <br />Chlorine (CAS 7782-50-5) <br />Ceiling 1.45 mg/m3 <br />0.5 ppm <br />Biological limit values <br />No biological exposure limits noted for the ingredient(s). <br />Appropriate engineering <br />Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates <br />controls <br />should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, <br />or other engineering controls to maintain airborne levels below recommended exposure limits. If <br />exposure limits have not been established, maintain airborne levels to an acceptable level. Eye <br />wash facilities and emergency shower must be available when handling this product. <br />Individual protection measures, such as personal protective equipment <br />Eye/face protection <br />Wear safety glasses with side shields (or goggles). <br />Skin protection <br />Hand protection <br />Wear appropriate chemical resistant 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 <br />Wear appropriate chemical resistant clothing. <br />Respiratory protection <br />In case of insufficient ventilation, wear suitable respiratory equipment. <br />Thermal hazards <br />Wear appropriate thermal protective clothing, when necessary. <br />General hygiene <br />When using, do not eat, drink or smoke. Always observe good personal hygiene measures, such <br />considerations <br />as washing after handling the material and before eating, drinking, and/or smoking. Routinely <br />wash work clothing and protective equipment to remove contaminants. <br />9.
