sop for waste disposal in laboratory{ keyword }

The reactivity classification includes substances that are unstable, react violently with water, detonate if exposed to some initiating source, or produce toxic gases. Radioactive ash is typically managed as a radioactive waste. (See Chapter 9, for more details. PDF Origination Date - December 2015 - West Virginia University Test the autoclave efficacy regularly using biological and chemical indicators. For these reasons, generators should be concerned about the ultimate disposal of their wastes; many choose to pay higher initial costs to have wastes incinerated so as to reduce their long-term liability. Consider rinsing emptied containers with water or a detergent solution. Resulting rinsate from containers previously holding acutely hazardous waste are hazardous waste and must be disposed of accordingly. The still bottom and aqueous phase must be handled as a mixed waste. Standard Operating Procedure (SOP) : Waste management of used - WHO The information needed to characterize a waste also depends on the method of ultimate disposal. The determination of whether a waste is regulated as hazardous is usually made either by the institutions EHS staff or by employees of the waste disposal firm. Once disinfected, the labware can be treated as a chemical waste. down the procedure for Disposal of Microbiology Waste. again and clean with using 2 % Teepol solution with water. Note that there is an optional alternative federal standard for the accumulation of waste within laboratories of colleges, universities, teaching hospitals, and certain nonprofit research facilities associated with colleges or universities. The collected slurry shall be disposed to ETP equalization point with the prior permission from Environmental Management Representative. In particular, dilute solutions should be used to avoid rapid heat generation. Examples include the following: Use nonignitable scintillation fluid (e.g., phenyl-xylylethane, linear alkylbenzenes, and diisopro-pylnaphthalene) instead of flammable scintillation fluid (e.g., toluene, xylene, and pseudocumene). 395 Pine Tree Road, Suite 210 Ithaca, NY 14850. Bucket shall be a wash For example, waste solvents can usually be mixed for disposal, with due regard for the compatibility of the components. As explained below, it is important that the generator verify that the waste transporter and TSDF operate in a way that is safe, compliant, and environmentally sound, and minimizes long-term liability. 2. Workers should contact their institutions EHS staff or local hazardous waste agency to determine their regulatory status and requirements for storing mixed waste for decay. (See the discussion of commingling in section 8.B.4.2, below.) These include substances that are water-soluble and those that do not violate the federal prohibitions on disposal of waste materials that interfere with POTW operations or pose a hazard. This especially makes sense if the rinsate is hazardous. Solid Waste Disposal Procedures - Office of Environmental Health and Safety Similarly, the use of a biological decontaminate can reduce a chemicalradioactive biological waste to a chemicalradioactive waste. Do you want to take a quick tour of the OpenBook's features? If not, contact your state water pollution control office to determine permitting and notification requirements and effluent limits. Note that regulators may consider a material to be a waste if it is abandoned or is inherently wastelike (e.g., spilled materials). If these regulations do not exist: implement at least the requirements of the ISO 15190 standard, article 23 on waste management. This rule promotes the use of standard microbiological practices including safe practices for handling biohazardous wastes. ), Incineration is the most common disposal method for laboratory wastes. Place fire extinguishers in several easily accessible places around the lab. In many cases, vehicles must be placarded. Laboratory experiments generate a great variety of waste, including used disposable laboratory ware, filter media and similar materials, aqueous solutions, and hazardous and nonhazardous chemicals. Communities tend to oppose waste incinerators, and on-site incineration is prohibitively costly for some radioactivebiological waste generators. Print the SOP and put it in a new folder entitled "Biosafety Manual". Analytical methods have been established by the U.S. Environmental Protection Agency (EPA), and environmental laboratories that use EPA methods are often certified or accredited. (Regulatory issues, specifically RCRA, are discussed further in Chapter 11, section 11.E.1. Present the SOP in a weekly staff meeting and indicate that all staff members have to read the SOP and sign the Read and Understand List when they have read it. 7.1.1 All potential waste streams that arise from laboratory operations needs to be assessed and an appropriate. I like to fullfill the need of curious people. used flammable (e.g., toluene) liquid scintillation cocktails. Analysis of laboratory unknowns is expensive, especially if EPA methods must be used, or the presence of a constituent must be ruled out, and handling unknowns is risky due to the possible presence of unstable, reactive, or highly toxic chemicals or byproducts. Write the SOP according to the protocol for writing a Procedure SOP in the Master SOP and use the template for a Procedure SOP attached to the Master SOP. It is recommended that supplementary information be kept in a separate, readily available record (e.g., laboratory information system, lab notebook), especially for very small containers or collections. Application of this simple principle ensures that the numerous state and federal regulatory requirements for waste handling are met and avoids unexpected difficulties, such as the generation of a form of waste (e.g., chemical, radioactive, biological) that the institution is not prepared to deal with. No commercial mixed-waste disposal facilities exist for waste contaminated with most toxic metals (such as mercury) or for lead-contaminated oils. These methods include neutralization, oxidation-reduction, distillation, digestion, encapsulation, and several forms of thermal treatment. Because the hazards of the materials being tested are unknown, the use of proper personal protection and safety devices such as chemical hoods and shields is imperative. When it can be done safely, knowledgeable laboratory staff may treat very small amounts of reactives that would otherwise pose a storage or transport risk. Incineration of mercury and other toxic metals is restricted; recycling, recovery, or encapsulation is environmentally preferred. Each container listed on the form must have a proper shipping name, hazard class, and EPA number. To ensure security and management oversight, chemical waste should be accumulated at or near the point of generation, and under control of laboratory personnel. Im Writer of Researchsop.com. (See 42 U.S.C. For example, if commingled waste contains significant amounts of halogenated solvents (usually >1%), disposing of the mixture can be considerably more expensive. As described above, small containers of compatible waste materials are placed in a larger container, usually a 30- to 55-gal drum, along with appropriate packing materials, as they are collected. Categorization procedures must account for the common laboratory waste management practices of placing small containers of waste chemicals into a larger overpack drum, and combining of many solvents and solutes into a single drum of flammable liquids. The overall sequence for testing is depicted in Figure 8.1 for liquid and solid materials. Laboratory Hazardous Waste Management and Disposal Manual Table of Contents 1. Most nonhalogenated organic liquids are less dense than water. 1. Reject any combination or sequence of methods that may create an unreasonable risk to waste handlers or the environment, or that might increase the overall risk. U and P lists pertain to. 15lbs pressure for 30 minutes. Improper and irresponsible disposal of chemical wastes down drains, to the Local Authority, refuse collection, or into the atmosphere is forbidden by law. The Centers for Disease Control and Prevention (CDC) of the U.S. Department of Health and Human Services and the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture promulgated rules under the Public Health Security and Bioterrorism Preparedness and Response Act of 2002 for the possession, use, and transfer of select agents and toxins. Sites may become Superfund sites through bankruptcy or other financial stress, illegal or improper disposal, act of nature (flooding, tornado, earthquake), or fire or explosion. To search the entire text of this book, type in your search term here and press Enter. Make provision for spill control in case of an accident during transportation and handling. Because proper management and disposal of laboratory waste requires information about its properties, it is very important that laboratory personnel accurately and completely identify and clearly label all chemical and waste containers in their laboratory, as well as maintain the integrity of source material labels. Some firms furnish consulting services or directly provide transportation or disposal services. and flammable waste liquids from laboratory operations are almost universally consolidated and used in fuel blending operations, typically to power cement plants. The count begins when the waste is brought to the central accumulation area from the laboratory or satellite accumulation area. For example, the USNRC or state authority may allow a licensee to manage a chemicalradioactive waste as a chemical waste without regard to radioactivity when the radioactive constituent concentration is less than what the USNRC specifies for an unrestricted area. Treatment is allowed as part of an experiment (or the last step) before it becomes a waste. However, these alternative standards require semiannual removal of all laboratory hazardous waste, whereas the standard satellite accumulation rule has no time limit for the accumulation of laboratory waste in unfilled containers smaller than 55 gal. The generators responsibilities are summarized below: inspecting waste containers to ensure complete and legal labeling, and container dating when required; waste accumulation, and managing accumulation areas for safety, security, aisle width, and separation of incompatibles; inspecting waste containers to ensure that they are always closed and in good condition, including repackaging of leaking containers; preparation and updating of waste management and contingency plans; sampling and characterization of routine wastes; sampling and characterization of unusual or new wastes; preparation of transportation documents; identification of disposal sites; and. There are many good compliance references to augment this book, and regulatory agencies should not be overlooked as another source of helpful information. 2. ). Ignitability. quantities and identification of waste generated and shipped; documentation of analyses of unknown materials if required; manifests for waste shipping as well as verification of disposal; inspection records, training records, contingency plans; and. If the waste supports the growth of an infectious agent that it contains, storage should be in a freezer to prevent the wastes infectious load from increasing. If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. Quality Control Testing of Raw Materials, APIs, and Finished Products. Recycling. treatment and safe disposal of these wastes to minimize any associated health risk with consideration to local context. Most of these methods are for commercially available chemicals, and so approved analytical procedures may not be available for some laboratory chemicals. In the right-hand column a link to an example Biosafety Manual procedure "Waste Segregation and Disposal" is provided. The selection of which activities to perform in-house and which services to handle through firms that specialize in waste disposal is dependent on the number, qualifications, and availability of in-house staff, organizational philosophy, and budgetary constraints. The waste shall be collected in specially designed collection vans from the storage area once a day by the contractor. PDF Standard Operating Procedure- Laboratory Waste Disposal (Chemistry) Elementary neutralization (see 8.D.1, below); the mixing of acidic and alkaline waste to form a salt solution, has long been encouraged as long as safety considerations are addressed. The treated waste can be discharged to the sanitary sewer (Rau, 1997). All chemicals must be characterized sufficiently for safe transportation off-site. Nevertheless, there are still justifiable and legal reasons to carry out such operations in the laboratory when hazards can be minimized safely. All cleanups are now paid for by organizations found by EPA to have contributed to the contamination. a radioactive waste. Objectives: '* Define and implement an effective system to provide for the sound and safe management of laboratory generated waste * Provide direction to laboratory staff for waste classification, storage, segregation, transportation, treatment and disposal. quantity of 5% Dettol/teepol solution in another bucket and all Petri- dishes/glassware The pros and cons of many other waste management methods are discussed earlier in this book (see Chapter 5, section 5.B, and Chapter 6, section 6.B). These strategies are described later in this chapter. The laboratory produces many different types of waste which may be dangerous for the environment and/or for the community. Incineration is normally performed in rotary kilns at high temperatures (12001400 F). per Annexure I. SOP : Post Comments waste chemicals that have not been used, because once used, the U or P listing does not apply; spills and spill cleanup material from U- or P-listed compounds; and. 3. Close the neck of the bag and twist it. Some radioactive methanolacetic acid solutions from gel electrophoresis can be recycled via distillation and the methanol reused. Hi. shall be done at least once a month for used media. Following categorization, select a hazard reduction procedure (section 8.D) or disposal option (section 8.B.6). For example, incineration can destroy oxidizable organic chemicals and infectious agents, waste feed rates can be controlled to meet emission limits for volatile radionuclides, and radioactive ash can be disposed of as a dry radioactive waste. Regardless of which activities a generator decides to conduct in-house, it is imperative that well-trained, qualified staff be available to conduct the waste management activities. A container or inner liner of a container that contained hazardous waste is empty under federal regulations if all waste has been removed by standard practice and no more than 2.5 cm (1 in.) tion. Depending on the requirements of the disposal facility, adjustment of the pH of aqueous waste may be required. This is a special concern with commingled waste solvents, which must be chemically compatible to ensure that heat generation, gas evolution, or another reaction does not occur. Examples of laboratory mixed waste include. When the solution is distilled by rotary flash evaporation, the distillate of acetonitrile, methanol, and water is nonradioactive and can be handled as a chemical hazardous waste. Although these procedures are very cost-effective, they require additional safety precautions, including the use of personal protective equipment and special and engineering controls. Atom Trained laboratory personnel who carry out the analytical procedures should be familiar with the characteristics of the waste and any necessary precautions. Place solid chemical waste, such as reaction byproducts or contaminated filter or chromatography media, in an appropriately labeled container to await disposal or pickup. 2.0 SCOPE : To provide a procedure for Disposal of Laboratory Waste. Long-term liability usually refers to Superfund liability. From a chemists point of view, it is feasible to reduce the volume or the hazardous characteristics of many chemicals by conducting reactions and other hazard reduction procedures in the laboratory. Procedure Conduct a Chemical Waste Determination . Disposal of Laboratory Waste SOP covers below points: Disposal of In process / Finished product. Pathology laboratory waste management involves the proper handling, segregation, collection, transportation, treatment, and disposal of waste generated during medical tests and procedures. Decisions on disposal options are best made here as larger quantities of waste are gathered. It is becoming increasingly common to include such reactions as the final steps in an experimental sequence. However, because the products of the reaction are often disposed of in the sanitary sewer, it is important to ensure that hazardous waste such as toxic metal ions is not a part of the effluent. Options can vary considerably between laboratories depending upon institutional capabilities and state and local laws. More details can be found in section 8.B.6, below. Carefully add a small quantity of the unknown to a few milliliters of water. A. Biohazardous waste is placed in red biohazard bags and autoclaved. Infectious waste and sharps containers that contain radionuclides can be autoclaved safely if the following precautions are satisfied: Monitor the air emissions of a test load to determine if the release of radioactive material is in compliance with USNRC license limits. Care must be taken because autoclaving of chemicalbiological waste at 120 to 130 C may result in the volatilization or release of the chemical constituent. Treatment for the chemical hazard must not create a radioactivity risk for personnel or the environment. The release of vapors to the atmosphere, via, for example, open evaporation or laboratory chemical hood effluent, is not an acceptable disposal method. The first category is based on properties of materials that should be familiar to all trained laboratory personnel. If the sample does not ignite, apply the ignition source again for 1 second. 8.B.2.4 In-Laboratory Test Procedures for Unknowns. Spams/ Promotional links are not allowed and shall be deleted upon review. Examples of these approaches include the following: Use 2.5-mL scintillation vials (minivials) rather than 10-mL vials. tap water followed by purified water and dry it in an oven at 180 C for 30 minutes. 20th International Conference on AIDS and STIs in AFRICA: 20th ICASA 2019, Strengthening enforcement of new tobacco law through capacity building of police officers, Mauritius validates its National Action Plan for Health Security, Over 20,000 Children Vaccinated Against Measles Rubella in Lesotho, Protecting nearly 800 000 people from bilharzia in four counties of South Sudan, Engaging private facilities to enhance real time surveillance. Larger institutions are advised to have an internal tracking system to follow the movement of waste. Do not use glass for aqueous waste if there is danger of freezing. Autoclaving and chemical decontamination are the methods of choice for decontaminating biohazardous waste. Referred to as PRPs (potentially responsible parties), these organizations include four classes of parties: current owner or operator of the site [CERCLA 107(a)(1)]; owner or operator of a site at the time that disposal of a hazardous substance, pollutant, or contaminant occurred [CERCLA 107(a)(2)]; person who arranged for the disposal of a hazardous substance, pollutant, or contaminant at a site [CERCLA 107(a)(3)]; and, person who transported a hazardous substance, pollutant, or contaminant to a site; that transporter must have also selected that site for the disposal of the hazardous substances, pollutants, or contaminants [CERCLA 107(a)(4)]. in Microbiology Lab. Environment, Health and Safety. Land disposal is the least desirable disposal method. We and our partners use cookies to Store and/or access information on a device. Do not store amines or corrosive materials in metal containers. "Y[0yD2 U ,V lZ u,"-]@&{ND4!30` 6jX The following test procedures are readily accomplished by trained laboratory personnel. Drivers. In general, existing commercial disposal facilities are in business to manage mixed waste from the nuclear power industry, not waste from laboratories. Add 0.5 mL of the liquid to be tested to a mixture of 1 mL of 10% aqueous potassium iodide solution and 0.5 mL of dilute hydrochloric acid to which has been added a few drops of starch solution just prior to the test. After checking with authorities, some laboratories flush small amounts of water-soluble nontoxic solids into the sanitary sewer with excess water. Laboratories that ship chemical waste off-site must address land disposal restrictions and treatability standards, which were put in place to discourage landfilling. The central accumulation area is an important component in the organizations chemical management plan. 246 0 obj <>stream lead contaminated with radioactive materials. Standard Operating Procedure- Laboratory Waste Disposal (Chemistry) compiled by: Chemistry Department Sustainability Committee Overview- *NEW* Glove recycling Hard plastic and transparent glass chemical containers Amber glass chemical containers Uncontaminated soft plastics Styrofoam Reduction or elimination of one of the waste hazards through waste management methods is often an efficient first step. When the identity of the material is not known, simple in-laboratory test procedures can be carried out to determine the hazard class into which the material should be categorized. Please note, however, that this book is not a compliance manual, and as such, its compliance information is incomplete. Regardless of the regulatory definitions of hazard, understanding chemical characteristics that pose potential hazards is a fundamental part of the education and training of laboratory personnel. Laboratory Quality Stepwise Implementation tool - WHO/OMS Extranet Systems microbial culture shall be discarded in the incineration pit. Scope PDF Standard Operating Procedures Waste Handling & Disposal Laboratory Waste Disposal Procedures - University of Idaho Procedure, QCD : Quality Control Department, GEN : General, Dept. (See Chapter 5, section 5.E.2, for storing chemicals according to their compatibility. Pollution should be prevented or reduced at the source whenever feasible. 5.4The autoclaved media, There is little incentive for the development of a commercial market to treat and dispose of laboratory multihazardous waste because most of the waste that laboratories generate is unique to laboratories and small in volume. The generator must obtain assurance, in terms of documentation, permits, records, insurance and liability coverage, and regulatory compliance history, that the chosen service provider is reliable. %PDF-1.5 % Commercial units are available for this process. For radioactive putrescible waste, off-site disposal requires special packaging, storage, and transport considerations. Assist the Biosafety Officer where needed (in purchasing waste containers if needed, making staff members read the Waste Segregation and Disposal SOP, etc. Rigorous application of waste minimization principles can often solve the problems of managing mixed waste. Based on feedback from you, our users, we've made some improvements that make it easier than ever to read thousands of publications on our website. The initial responsibility for implementing this hierarchy rests with trained laboratory personnel. Use hand gloves, safety goggles and mask while disposal of hazardous chemicals. Media shall be remove According to federal regulations, storage at a central accumulation area is normally limited to 90 days, although more time is allowed for small-quantity generators or other special situations (180 or 270 days). Combustible materials have a flash point between 60 and 93 C (140 and 200 F). these definitions are unique, especially the definition of waste having the characteristic of toxicity. Practices that implement this strategy include purchasing only what is needed, keeping chemical inventories to prevent the purchase of duplicates, and reusing excess materials. (See the discussion of disposal methods in sections 8.B.6 to 8.B.7, below.). Note that. Install a safety shower and one or more eyewash stations. Requirements vary by state, locale, and the individual laboratorys plumbing and sewer system, as well as other facility discharges and treatment systems that the laboratory is part of. The OSHA Occupational Exposure to Bloodborne Pathogens rule (29 CFR 1910.1030) established federal requirements for the collection and containment of certain laboratory wastes that contain human blood or body fluids for the purpose of preventing exposure of personnel to bloodborne pathogens. Add 1 to 3 mL of the liquid to be tested to an equal volume of acetic acid, add a few drops of 5% aqueous potassium iodide solution, and shake. PDF Standard Operating Procedure - Emory University In certain states small-scale treatment is allowed within a laboratory, sometimes as part of a permit-by-rule allowance. The management of radioactivebiological laboratory waste can be difficult because of limited on- and off-site disposal options. Infectious waste should be stored separately in a secure area. H4 &F h?w 0 Packaging and labeling are key parts of this initial in-laboratory operation. These standards are completely optional, at the discretion of the educational or research institution. Therefore it is important that the laboratory adheres to strict procedures regarding waste disposal and processing. Federal regulations regarding transport and incineration may apply to the off-site management of nonlaboratory biohazardous waste, such as waste generated in medical or health care settings. This SOP covers procedures for the disposal of waste from human or animal healthcare and or related research according to Chapter 18 of the EWC categorization and includes; procedures for the treatment of Ready to use SOPs, Protocols, Master Plans, Manuals and more Worldwide Regulatory Updates Pharmaceutical News Updates Interview Questions and Answers All Guidelines in One Place. These difficult and complex management issues can also make it difficult to promote and sustain prudent pollution prevention practices. It is essential that you understand how to operate They are responsible for evaluating hazards, providing information necessary to make an accurate waste determination, and assisting in the evaluation of appropriate strategies for management, minimization, and disposal.
