US. NIOSH: Pocket Guide to Chemical Hazards <br />Components Type <br />Chlorine (CAS 7782-50-5) <br />Ceiling <br />Value <br />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 should be used. Ventilation rates should be matched to conditions. If <br />controls <br />applicable, use process enclosures, local exhaust ventilation, or other engineering controls to <br />maintain airborne levels below recommended exposure limits. If exposure limits have not been <br />established, maintain airborne levels to an acceptable level. Eye wash facilities and emergency <br />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 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 />Skin protection <br />Other Wear appropriate chemical resistant clothing. <br />Respiratory protection If engineering controls do not maintain airborne concentrations below recommended exposure <br />limits (where applicable) or to an acceptable level (in countries where exposure limits have not <br />been established). an approved respirator must be worn. <br />Thermal hazards Wear appropriate thermal protective clothing, when necessary. <br />General hygiene When using, do not eat, drink or smoke. Always observe good personal hygiene measures, such <br />considerations as washing after handling the material and before eating, drinking, and/or smoking. Routinely wash <br />work clothing and protective equipment to remove contaminants. <br />9.
