  20. 20. • Double bags – adequate strength and no leaks • Labelled as Covid19 • The (inner and outer) surface of containers/bins/trolleys should be disinfectedwith 1% sodium hypochlorite solution daily • Separate storage and transportsystem Guidelines for handling of COVID-19 patients wastes.
  21. 21. Nurses role in Biomedical Waste Management • It starts from segregation till the treatment of waste. • Ensure that waste bags/containers are properly sealed and labeled. • Bags should not be filled completely, so that bags can be picked up by the neck again for further handling. Hand should not be put under • At a time one should be lifted. • Manual handling of waste bags should be minimized to reduce the risk of needle stick injury.
  22. 22. Continued.. • Regular visit to all the wards and high risk units. • Ensuring that all samples (Blood, urine and stool etc.) are collected and disposeproperly. • Monitoring and supervising the staff weather they are doing safe disposal of waste as colour coded. • Prevention of hospital acquired infections byfollowing universal precautions.
  23. 23. Continued.. • Avoid needle stick injuries and body fluid exposure. • Collect waste when the bin is3/4th full. • Avoid using common lift to movewaste. • Avoid spillage & Clean spillswith disinfectant. • Immunize self and others time to time andmaintain records. • Report major accidents.
  24. 24. 1.Metal sharps management : • Needle cutter orburner Prevents reuse/recap Reduces the volume Recycling syringebarrels after disinfection • Handed over to theCBWTF or sharp pits BMW Management in Special Situations
  25. 25. 2.Glassware management: • Pretreatment – 1% chlorine solution for 20 mins or Autoclave • Handed over to the CBMWTF for final treatment and disposal/recycling BMW Management in Special Situations
  26. 26. 3.Cytotoxic drugs wastes • Highly hazardous • Neverlandfilled or directly discharged into the sewagesystem • Appropriate PPE should beworn • Receiving and transport policies – trained persons • Unpacking – ventilatedarea with negative pressure BMW Management in Special Situations

  29. 29. Cytotoxic wastes disposal techniques: • Return to the supplier • Incineration at higher temperature – 1200 Deg Cel • Chemical degradation -Require expertise -Sodium hypochlorite,hydrogen peroxideand fenton reagent • Newer methods : Encapsulation/inertization BMW management in special situations
  30. 30. 4.Liquid waste management • Pretreatment – 1 to 2% sodium hypochlorite solution for 30 mins • Effluent treatment plant – remove thesuspended solids and organicmatter • Prevents direct mixing of hospital drainage system with the municipal drainagesystem BMW management in special situations
  31. 31. • Gloves 2 pairs • Apron • Surgical mask • Goggle • Shoe over or plastic bag to cover theshoes • Sodium hypochlorite solution • Absorbent material like newspaper or blottingpaper • Waste collection bag Blood Spill Kit
  32. 32. Any spillage, attend immediately,mark the spillage area,put wet floor signage Wearappropriate PPE Remove any broken glass pieces with forceps and discard in Puncture proof and leak proof boxes or containers with blue coloredmarking Confine the spill by placing absorbent cloth or paper to solidify and clean with soap and water Attend to Body Fluid Spill
  33. 33. Clean with chlorine based disinfectant Smallspill (<10cm) Largespill (>10 cm) 0.05% sodium hypochlorite solution 0.5% sodium hypochlorite solution Contact time – 10 mins Rinse the area with clean water Discard the PPE and the wastes in appropriate bags and Perform handwash Immediately Attend to Body Fluid Spills!
