Write a short note on biomedical waste disposal in pathology lab

After we pick up your pathological waste, we take it to an incinerator where it is safely disposed of. Many hospitals autoclave their microbiological wastes prior to transport to the waste storage area, even if treating on site.

Wastes containing both infectious material and sharp objects create particular hazards for anyone handling them, or coming into contact with them.

And due to its unique qualities and challenges, pathological waste calls for different collection and disposal procedures than your typical red-bag waste. A few states e. Pathological waste differs from anatomical waste in that these are typically samples of tissues that are examined in a laboratory setting to understand the nature of the disease or make a diagnosis.

Some pathological waste may be hazardous if it was in contact with hazardous chemicals such as chemotherapy drugs. Overview of Pathological Waste Disposal Apr 14, Pathological waste is a very common type of waste generated by numerous healthcare and medical research and testing facilities.

In either case, it should be labeled accordingly. For the purpose of proper classification and disposal, teeth, hair and nails are not considered pathological waste in Maryland.

It possesses a few qualities that may warrant different disposal procedures. Pathological waste, specifically anatomical waste such as organs, can be saturated or filled with bodily fluids. It may also be infectious or potentially infectious. Most of the states that make special provisions for pathological waste also have special requirements for microbiological waste.

Here are a few tips and some basic overview to help you make sure you are doing it right! For those state that do allow alternatives to incineration for this waste stream, steam sterilization autoclaving is the most common method indicated. You are free to choose the right collection container based on the amount of pathological waste you generate, as well as the size and location of your storage area.

Also typically included in this category are discarded etiologic agents and wastes from the production of biologicals and antibiotics likely to have been contaminated by organisms likely to be pathogenic to healthy humans, as well as waste that originates from clinical or research laboratory procedures involving communicable infectious agents.

What is Considered Pathological Waste? Special measures, such as double-bagging or use of absorbents, may need to be taken to prevent leakage. It is also important to note what materials your laboratories are working with, as there are special guidelines from CDC on how to handle infectious microorganisms at biosafety level BSL 3 and BSL 4.

Review state regulations appropriately. At BWS, we help numerous medical institutions dispose of pathological waste on a daily basis.

Pathological waste has to be refrigerated in order to slow down decomposition and prevent odors. Other states allow alternative treatment methods, but spell out in detail which methods are allowed. Some states require either incineration or interment for pathological waste, apparently with no provision for exceptions.

Commonly used containers include cardboard boxesbiohazard toters and carts lined with red bags.

Sharps are singled out for special regulatory provisions by more states than any of the other medical waste categories. Discarded cultures, culture dishes and devices used to transfer, inoculate and mix cultures, stocks, specimens, live and attenuated vaccines and associated items are considered microbiological waste, IF they contain organisms likely to have been contaminated by organisms likely to be pathogenic to healthy humans.

Animal Waste Many facilities have affiliated animal research laboratories as part of their organizational footprint. Anatomical wastes are typically distinguished as recognizable human organs, tissue and body parts, and may require special treatment under some state regulations.

Some healthcare organizations have also gone a step further to get written guidance from the state department of health on proper disposal practices where the regulation leaves disposal up to interpretation. Tissue remains resulting from such processing can often be disposed of via a sanitary sewer system or treated as biohazardous waste.

This waste category includes animal carcasses, body parts, bedding and related wastes that may have been exposed to infectious agents during research, production of biologicals, or testing of pharmaceuticals.

Check the state definition for RMW to see if this waste category is defined more specifically in a particular state. There are basically two ways to address the risk of infection from sharps—mitigate the infective potential, or mitigate the sharpness.

Amputated tissues, organs and body parts Tissue samples collected for analysis Animal tissues, organs, body parts or carcasses used in research Pathological Waste Collection Pathological waste should be separated from the rest of the red-bag regulated medical waste.

Others require that they be rendered unrecognizable. While these fluids are not considered infectious under OSHA unless meeting the standard above, it is important to check state regulations.

Isolation Wastes Wastes from Highly Communicable Diseases This waste category includes biological waste and discarded materials contaminated with blood, excretion, exudates or secretion from humans or animals who are isolated to protect others from highly communicable diseases Lassa fever virus, Marburg virus, monkey pox virus, Ebola virus and others See Table 27 from the CDC Guidelines on Environmental Infection Control, It typically originates from surgical procedures or research that involves removal of organs, tissues or body parts.

This category includes sample of these fluids taken in hematology labs, as well as drainage from surgery, and urine or feces when visibly contaminated by blood. Pathological Waste Disposal Pathological waste can be packaged into a variety of containers.

Many states spell out detailed regulations for sharps containers, including conditions to ensure that they are resistant to punctures, and that they are clearly labeled. Pathological waste is a subcategory of biohazardous waste.Typical Categories of Medical Waste. research studies, or another hospital procedure, and which are intended for disposal.

Pathological waste differs from anatomical waste in that these are typically samples of tissues that are examined in a laboratory setting to understand the nature of the disease or make a diagnosis.

Please note that. Overview of Pathological Waste Disposal. Apr 14, Pathological waste is a very common type of waste generated by numerous healthcare and medical research and testing facilities.

And due to its unique qualities and challenges, pathological waste calls for different collection and disposal procedures than your typical red-bag waste. Guidelines for waste disposal Waste Preparation: 1) Avoid delay in waste removal. 2) Collection and segregation of waste according to type and degree of hazard 3) Packing of waste materials in approved containers which is neither overfilled nor leaking.

washable and easily disinfected PVC containers with a capacity of 40– 50 liters should be used. Categories of biomedical waste Ten categories of biomedical waste have been described in schedule I of BMW rules (Table1).

Human anatomical waste is usually generated in operation theatres but a number of specimens are sent to the pathology department for diagnosis. Hence it is a liability of the laboratory to dispose the tissues as biomedical. Write short notes on: a) Acquired Coagulopathies b) Alloimmune thrombocytopenia c) Biomedical waste disposal in Pathology Lab d) Blood components separation and uses e) Gel method in blood grouping and cross matching f) Herediatary disorders of red cell permeability g) Serum transferrin receptor assay h) Thermoelastography (T.
