If there is direct skin contact with hazardous waste, the affected area must be immediately washed with antiseptic solution and reported to the infection control team.
Proper training on waste management and infection control should be mandatory for all hospital staff, including cleaners, nurses, and laboratory technicians. Regular workshops, drills, and refresher training should be conducted to ensure compliance with infection prevention protocols.
5. Spill and Injury Management
Accidental spills of infectious waste must be handled immediately and safely. Staff should follow the hospital spill management protocol to contain and disinfect the area.
For small spills, absorbent material such as paper towels should be used to soak up the liquid, followed by disinfection with a hospital-grade disinfectant (e.g., 1:10 bleach solution).
For large spills, staff should wear full PPE and use a chemical disinfectant (e.g., sodium hypochlorite 1%) to clean the area. The contaminated waste should be collected in a biohazard bag and disposed of in accordance with infection control guidelines.
In case of needle-stick injuries or sharps exposure, staff should follow the post-exposure prophylaxis (PEP) protocol:
Immediately wash the wound with soap and running water.
Do not squeeze or rub the area to avoid spreading contaminants.
Apply an antiseptic solution (e.g., povidone-iodine).
Report the incident to the infection control officer.
Seek medical evaluation for possible exposure to HIV, Hepatitis B, or Hepatitis C.
Follow up with post-exposure prophylaxis (PEP) if necessary.
6. Safe Waste Transport and Disposal
Medical waste should be transported in covered, labeled, and leak-proof containers to avoid exposure during transit. Staff must ensure that waste is secured properly and that transport vehicles are cleaned and disinfected regularly.
Highly infectious waste, such as materials from COVID-19, tuberculosis, or hemorrhagic fever patients, must be handled with extra precautions. It should be double-bagged, labeled, and transported in sealed containers to prevent leaks or spills.
Upon reaching the treatment facility, biomedical waste should be processed using approved disposal methods such as incineration, autoclaving, or chemical disinfection. Staff must ensure that no untreated infectious waste is released into the environment.
After handling waste, all PPE should be removed carefully to avoid self-contamination. Gloves should be removed first, followed by gown, face shield, and mask. Hands must be thoroughly washed after removing PPE.
7. Monitoring and Compliance with Regulations
All healthcare facilities must have a waste management committee to ensure compliance with infection prevention policies and waste disposal regulations. Regular audits and inspections should be conducted to identify areas for improvement.
Records of waste generation, transportation, and disposal must be maintained to track compliance with national biomedical waste management laws. Failure to follow waste management protocols can result in fines, legal action, and increased risk of infections in healthcare settings.
All staff handling waste should be vaccinated against Hepatitis B, Influenza, and COVID-19 to reduce the risk of occupational infections.
