on site storage is aka?
interim storage
The place within a department or floor of a healthcare facility
where waste is stored temporarily for safe retention before being brought to the central storage area
interim storage/ on site storage
what is the mechanism for autoclaving?
temperature, pressure, thermal oxidation
what is the mechanism for autoclaving?
temperature, pressure, thermal oxidation
other term for autoclaving?
steam sterilization
what is the temperature of autoclaving?time? psi?
121-134 c, 15-20 minutes and 15 psi/2 bar
is very useful, especially in duty rotations in the
micro department in the lab
autoclaving
what does the autoclave capable of killing?
killing the strongest of bacterias such as bacterial spores
High temperature dry oxidation at greater than 850 C in the primary chamber and 1100 C in the secondary chamber
incineration
what are the principles of incineration?
temperature, time and turbulence
what are the principles of incineration?
temperature, time and turbulence
retention time of incineration?
2 sec.
what is the temperature of primary incineration? secondary incineration?
850c
1100c
what waste does the incineration treat?
waste that can’t be recycled, reused or disposed of in a sanitary landfill
what kind of disinfection is the hypochlorite solution?
chemical disinfection
used to clean up spills
chemical disinfection
dilution rate of chemical disinfection?
1:10
it is a waste fed to waste-grinding device?
microwave irradiation
how many microwave irradiation units is being used in the microwave radiation? time?
six microwave irradiation units, 2 hours
Compacted waste-filling trench
sanitary landfill
You dig a trench and put the waste there
landfill
Predominant method of waste disposal in developing countries
open dumps
a dumping process where it Negatively affects the organisms living in the ocean
ocean dumps
May cause illegal dumping problems and groundwater contamination, air pollution, pest and health hazards
open dumps
Very dangerous, especially for people living near the site as they are exposed to a site that is subjected to bacteria and viruses
open dumps
When companies and industrial countries send their toxic wastes to disposal sites in third world nations
garbage imperialism
who are recipients of locally unwanted land uses?
poor neighboring countries
how many shipping containers left from vancouver?
103
how many shipping containers were labelled as recyclable plastics?
14
