healthcare waste refers to all ____ and _____ waste generated
solid and liqud
according to WHO,
75 to 90% of waste -
10-25% of waste -
non hazardous
hazardous
high income countries - produce ____ of hazardous waste
low income countries - produce ____ of hazardous waste
0.5kg
0.2kg
true or false
proper segregation of hazardous and non hazardous waste in low income countries tends to be the less implemented, thus making the real quantity of hazardous waste much higher
true
identify the category of health care waste:
that can cause cuts, pricks or puncture wounds
sharps
identify the category of health care waste:
expired, split and contaminated pharmaceutical products, drugs and vaccine
pharmaceutical waste
identify the category of health care waste:
discarded chemicals (solid, liquid or gaseous) generated during disinfection and sterilization procedures.
chemical waste
identify the category of health care waste:
refers to waste exposed to radionuclides including radioactive diagnostic materials or radiotherapeutic
radioactive waste
identify the category of health care waste:
waste that have not been in contact with communicable or infectious agents, hazardous chemicals or radioactive substances
general waste / non hazardous
identify the category of health care waste:
tissue sections and body fluids or organs derived from biopsies, autopsies or surgical procedures sent to the lab for examination
pathological and anatomical waste
identify the category of health care waste:
it refers to all waste suspected to contain pathogens or toxins in sufficient concentration that may cause disease to a susceptible host
infectious waste
it is considered the most dangerous health care waste
sharps
true or false
treatment and disposal of healthcare waste may pose health risks directly through the release of pathogens and toxics pollutants into the environment
false - indirectly
which disposal of health care is not allowed in Philippines
incineration
it is the most important step in proper management of healthcare wastes
green procurement policy
safely reusing, recycling and recovering waste are collectively termed as
resources development
it refers to either finding a new application for a used material or using the same product for the same application repeatedly
reusing
it refers to the processing of used materials into new products
recycling
recovery of waste can be defined in 2 ways:
energy recovery
recycling , composting and energy recovery

true
hazardous shall never be mixed or disposed down the ____ but shall be stored in strong chemical _______ or amber disposal bottles
drain
resistant leak-proof containers
difference between sterilization and disinfection
sterilization - kills all microorganism
disinfection -reduces the level of microorganism present in the material
identify the treatment and disposal of health care waste:
it is a technology that typically incorporates some type of size reduction devices. shredding is done before disinfection
microwave
identify the treatment and disposal of health care waste:
chemicals are added to healthcare waste to kill or inactive present pathogens
chemical disinfection
identify the treatment and disposal of health care waste:
it uses enzyme mixture to decontaminate health care waste
biological waste
identify the treatment and disposal of health care waste:
it is the thermal decomposition if health care waste in the absence of supplied molecular oxygen in the destruction chambers where the waste is converted to gas, liquid, solid form
pyrolosis
identify the treatment and disposal of health care waste:
use of steam sterilization to render waste and is an efficient wet thermal disinfection process
autoclave
identify the treatment and disposal of health care waste:
involved the filling of containers with waste, adding and immobilizing material and sealing the containers
encapsulation
identify the treatment and disposal of health care waste:
it is suitable for pharmaceutical waste that involves the mixing of waste with cement and other subs before disposal
intertization
after treatment, health care waste are usually disposed in _____
landfills
it is an engineered site designed to keep waste isolated from the environment
landfill
landfill must secure proper permits from the _____ before it can accept waste
