Methods and materials for This product is miscible in water containment and cleaning up Large Spills: Stop the flow of material, if this is without risk. Use water spray to reduce vapors or divert vapor cloud drift. Dike the spilled material, where this is possible. Absorb spillage to prevent material damage. Use a non-combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal. Prevent entry into waterways, sewer, basements or confined areas. Following product recovery, flush area with water. Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination Never return spills to original containers for re -use. For waste disposal, see section 13 of the SIDS. Environmental precautions Avoid release to the environment. Inform appropriate managerial or supervisory personnel of all environmental releases. Prevent further leakage or spillage if safe to do so. Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling Do not breathe mist or vapor. Do not get in eyes, on skin, or on clothing. Provide adequate ventilation. Wear appropriate personal protective equipment. Avoid release to the environment. Observe good industrial hygiene practices. Conditions for safe storage, Store locked up. Store in corrosive resistant container with a resistant inner liner. Keep only in the including any incompatibilities original container. Store away from incompatible materials (see Section 10 of the SDS). 8. Exposure controls/personal protection Occupational exposure limits US.

ACGIH Threshold Limit Values Components Type Value Sodium hydroxide (CAS Ceiling 2 mg/m3 1310-73-2 ) US. NIOSH: Pocket Guide to Chemical Hazards Components Type Value Sodium hydroxide (CAS Ceiling 2 mg/m3 1310-73-2) US. Workplace Environmental Exposure Level (WEEL) Guides Components Type Value Sodium hypochlorite (CAS STEL 2 mg/m3 7681-52-9) Biological limit values No biological exposure limits noted for the ingredient(s). Appropriate engineering Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates controls should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. Eye wash facilities and emergency shower must be available when handling this product. Individual protection measures, such as personal protective equipment Eye/face protection Wear safety glasses with side shields (or goggles) and a face shield. Skin protection Hand protection Wear appropriate chemical resistant gloves. Be aware that the liquid may penetrate the gloves. Frequent change is advisable. Nitrile or neoprene gloves are recommended. Other Wear appropriate chemical resistant clothing. Respiratory protection In case of insufficient ventilation, wear suitable respiratory equipment. Thermal hazards Wear appropriate thermal protective clothing, when necessary. General hygiene Always observe good personal hygiene measures, such as washing after handling the material considerations and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants.
