Standard Operating Procedure <br /> For work with HAZARDOUS WASTE MANAGEMENT. <br /> PI: Jianhua Ren Building(s): Classroom Building <br /> PI Signature: Room Number(s): CR 121 <br /> Revision/Review Date: Designated Work Area:Research Laboratory <br /> Departmental Approval? Yes ® No ❑ Departmental Signature: <br /> EH&S Approval? Yes ❑ No I ❑ I EH&S Signature: <br /> Instructions for each section of this form are available and should be referenced as you complete this SOP form. If an <br /> experimental protocol has been written and incorporates all of the relevant safety information required in this form, it <br /> can be used(only with Department and EH&S approvals) in lieu of this template. <br /> Summary(Overview): <br /> The purpose of this procedure is developed to reduce the potential of illness or injury by implementing <br /> practices to identify and effectively manage the handling of hazardous waste. Consult with the Risk <br /> Management Department for additional guidance on how to handle/manage hazardous waste. <br /> The procedure describes the neutralization of aqueous acid/base-waste in the lab. Researchers will be able to <br /> apply the procedure to safely dispose of neutral aqueous solutions. <br /> 1. Hazard Identification <br /> a. Pre aration and Use: <br /> To properly store hazardous materials,make sure to use appropriate hazardous waste containers.Use sealable <br /> containers that prevent the release of harmful chemical substances. Make sure that containers are compatible <br /> with the waste being stored and are manufactured with weather and corrosion resistant materials. Ensure that <br /> all employees are thoroughly familiar with proper waste handling and emergency procedures,relevant to <br /> their responsibilities during normal facility operations and emergencies. <br /> Procedures used: Benchtop(diluted acid/base solutions) or fume hood(concentrated acid/base solutions). <br /> The procedure will be applied to waste as it accumulates in the laboratory because of routine daily research <br /> activities. <br /> Note:If identified as a process,provide additional detailed procedural steps for the use of each hazardous chemical in Section 5,below. <br /> b. Chemical Hazards and Risk: <br /> Chemical waste can be corrosive,toxic, flammable, chronic to health, O O 0harmful to the environment, and explosive,which can result in <br /> 41> <br /> injury, fire,or explosion. ❑ ❑x ❑x ❑ <br /> Flammable Toxic Corrosive Oxidizer <br /> Acid/Base waste is corrosive and can have severe and potentially <br /> fatal effects for individuals exposed to it. Environmental hazard is OI> 4> <br /> high as well especially if the neutralization waste contains heavy <br /> metal salts. ❑ <br /> Explosive Environmental Harmful Chronic <br /> SDSs for common acids and bases used in the lab are available <br /> below: <br /> Hydrochloric acid (HCI) <br /> hitps://fscimage.fishersci.com/msds/I I 155.htm <br /> Sodium hydroxide (NaOH) <br /> hLtps:Hfscimage.fishersci.com/msds/21300.htm <br />
