Blood borne disease

Ex: Hep A, Hep B, AIDS through needle stick injuries

Direct contact

Vector borne diseaseEx: malaria, yellow fever, sleeping sickness

Water borne disease

Ex: Typhoid, Colera, HepA

Air borne disease

Ex: TB

WATER All heathcare facilities need a clean water supply! Recent assessment reveal that many need new boreholes

installed down to the groundwater in the aquifer, costing approximately $8,000. Other clinics need repairs to the existing borehole, costing approximately $1-3,000.

Do we need to explore alternative?

Almost one third of the healthcare facilities reported not always having a water supply.

Rainwater is free and relatively good water quality.

Catching rain “free-falling” is usually better than from a roof yet there is no one right way, only what works best for your clinic at this time.

Rainwater Catchment

Simply roll out a sheet of plastic - cleaner surface area than most roofs !

Healthcare Waste is Dangerous!

If handled, treated or disposed of incorrectly it can spread disease - poisoning people, livestock, wild animals, plants and whole ecosystems.

The Waste Management Plan Steps to creating a best management plan at your

healthcare facility.

– The MSF Segregation Plan ! works well for them

IncinerationGlobal and local air pollution

DRUM BURNER – not effective but common

INCINERATION for disposal of highly hazardous waste is not the best “environmentally friendly” technology, but is appropriate for Liberia at this time. Use of functional, high-temperature structures is recommended by the MoH EPI.

General Waste

General waste (non-risk) including uncontaminated waste similar to domestic waste (paper, plastic wrappings, food waste); may represent about 80% of the total waste production from healthcare facilities.

Typical Percentages of Healthcare Waste

Hazardous Waste Infectious–

Wastes thought to contain low concentrations of infectious agents, such as disease causing bacteria, viruses, parasites, and fungi, that could spread the disease.

Examples; tissues, swabs, wound dressings, bandages; materials or equipment that have been in contact with infected patients; blood stained cloth, human excretions such as pus, feces and vomit from patients without highly infectious diseases; wash water.

Hazardous Waste

-PathologicalTissue or body fluids from humans or animals without highly infectious diseases

Examples; blood, body parts, organs, animal carcasses

Highly Hazardous WasteSharps Sharp objects that can easily cut or injure a handler.

Used hypodermic needles are the most common and dangerous, as they are often contaminated with highly infectious blood.

Examples; syringe needles, scalpels, knives, blades, infusion sets, broken glass

Highly Hazardous Waste

- Non sharps and highly infectiousContain high concentrations of highly infectious agents and pose an extreme health hazard.

Examples; body fluids, such as blood, from patients with highly infectious diseases; microbial cultures.

SUMMARY

Crushing glass

Red metal glass crusher and cardboard box of glass ampoules - waiting to be destroyed.

Example of a Sanitary Pit, unlined for large amounts of general waste - leaching into ground and decomposition will occur. For small amounts of general waste without plastics, a composting bin can be used. A lined sanitary pit would be with thick plastic, or bricks on bottom & sides of pit, for hazardous waste if incinerator is not available. Additions of lime or ash will inhibit decomposition.
