Contain spill and <br />pump into marked containers for reclamation or <br />disposal. For small spills, neutralize with soda <br />ash or dilute caustic soda solution and flush to <br />a sewer system in accordance with regulatory <br />permit requirements. If possible, clean up spill <br />area on a dry basis and then flush with plenty <br />of water. <br />Regulatory Status <br />§311 of the Clean Water Act lists Muriatic acid <br />as a hazarddus substance which, if discharged <br />into or upon water, may require immediate <br />esponse to mitigate danger to public health and <br />f— welfare. The Act specifies procedures to be <br />followed in the event of accidental spillage as <br />well as civil penalties and fines to be levied. <br />Spills of Muriatic acid of 5,000 or more pounds <br />Threshold Limit Value& <br />The American Conference of <br />Governmental Industrial Hygienists <br />(ACGIH) has established a Ceiling <br />Limit of 5 ppm (7 mglm') for HCI. <br />None established. <br />the reaction with most metals. Chlorine gas will <br />be released by mixing with strong oxidizers. <br />Conditions To Avoid: Avoid contact with <br />metals and strong oxidizers. <br />Use equipment designed for acid service for <br />handling and storage. <br />Waste Disposal Method: Dispose of spilled <br />or waste product, contaminated soil and other <br />contaminated materials in licensed landfill or <br />treatment facility in accordance with all local, <br />state and federal regulations. <br />reported to the National Response Center, <br />1-800.424.8802. <br />The shipment of Muriatic acid is regulated by the <br />U.S. Department of Transportation. It is classified <br />as a Corrosive Material, requires a Corrosive DOT <br />label and is assigned UN 1789 as an international <br />identification number (49 CFR § 172.101). <br />
