Question	Answer
which it is a form of encapsulation that uses cement concrete • mixing ways with cement • this is suitable for pharmaceutical waste so 65% of the pharmaceutical work or waste you put 15% lime and 15% and 5% water	inertization
we have this enzyme mixture and it is used for the removal of water from wastewater disposal	Biological process
• it is a waste disposal method that packs hazardous materials in containers made of non- reactive materials • filling containers with waste • adding with immobilizing materials like concrete plastics are stills or boreal or storage • once the medium has dried containers are sealed is sealed and disposed of on landfill or burial fit	Encapsulation
is sterilization, meaning it can kill all the microorganism and it is under moist heat or steam under pressure.	autoclave
121 degrees celsius 15 psi for 15 minutes for?	media, liquids and instrument
it basically exposed to microwaves • 100° celsius for at least 30 minutes • it is a form of sterilization	microwave
an autoclave 132 degrees celsius with 15 psi for 30 to 60 minutes for?	infectious medical wastes
it is also called thermal decomposition	pyrolysis
• Reduces the number of microorganisms • Treatment with disinfectant • Minimize the microbial	disinfection
• not all of the ways requires treatments some needs treatment to prevent human and environmental from any waste contacts risk infectious • To prevent the spread ng infectious waste	treatment and disposal
• Regular on-site collection to facilities waste area or storage	on-site collection
• Only accredited DENR transporters and official waste collectors are allowed to transport ways to TSD (TREATMENT STORAGE DISPOSAL FACILITY) facility or to the final disposal site	off-site transportation
• Personnel must be trained • wearing complete PPE with the trolley	on-site transportation
kitchen waste, paper and tissues and water bottles and cans	general waste (green)
needles and cut glasses	sharps (red box pit)
antibiotic vials, metallic implants, glassware materials except cytotoxic	glassware bin (Blue)
soiled, anatomical, chemical liquid, cytotoxic, laboratory waste, expired and discarded medicines	infected wastes (yellow bin)
- is a basic separation of different categories of waste and by segregation reduce the risk as well as a cause of handing and disposal	segregation
it is the process of changing the biological and chemical characteristic of ways to minimize its potential to cause harm.	treat
• it is the most critical step in biomedical waste management it reduces the amount of waste that needs special handling and treatment effective segregation process prevents the mixture of medical waste like sharps with general ways, of course, do not mix any infectious waste with non infectious waste • also by segregating we prevent the illegal use of certain components of medical waste like used of syringes needles	waste segregation and storage
it is a process of used materials into new products • for sample: papers laboratory, boxes, bottle	recycle
for the waste that cannot be safely reused recycle or recover the end of pipe approach is implemented. • treatment and disposal	end pipe
- for the recovery waste is recovered to fuel for generating electricity or for direct heating of premises. • it also encompasses subsets of waste recovery composting and energy recovery	recover
depositing, placing, or releasing any healthcare waste into Air, land or water • take note that not all types of ways require treatment it can be immediately disposed	dispose
it's either finding a new application for material or using the same product for the same application repeatedly.	reuse
• waste prevention and waste reduction • so the healthcare facilities are encouraged to avail of services that are harmful to the environment and to purchase less polluting products • we prevent those infectious or harmful materials or substances if can’t be prevented then maybe we can reduce waste reduction so this is the most or more preferable for health care waste management	green procurement
• the important step in the proper management of healthcare waste in using an approach known as the green procurement policy	health care waste management system
• as all solid or liquid waste of the healthcare facilities and of course, the laboratory is included	health care waste
• the source: could be wet floors, heavy boxes, and even patients • possible injury: falls, sprains, or strains	physical hazard
type of fire extinguisher for class a fires only	water and foam
type of fire extinguisher for class b and class c fires	carbon dioxide
type of fire extinguisher for class a, b, and c fires	dry chemicals
type of fire extinguisher for class d only	dry powder
type of fire extinguisher for class k	wet chemicals
TYPES OF FIRES: • These are fires in ordinary combustibles o wood paper cloth rubber and many plastics	1. CLASS A
types of fires such as gasoline, petroleum, greases, tars, oils all based paint solvents and alcohols	class B
type of fires involving energized electrical equipment such as computer servers, motors, transformers and machines	class C
type of fires such as cooking oils and greases	class k
combustible metals such as magnesium , titanium, zirconium, sodium,, lithium and potassium	class D
how to properly operate a fire extinguisher	Pull Aim Squeeze Sweep
essntial steps ti take if you discover fire	Rescue, Alarm, Contain, Extinguish
• Source: Bunsen burners and organic chemicals • possible injury: burns or dismemberment • laboratories are required to have post evacuation routes and detailed plans to follow in the event of a fire • laboratory personnel should be familiar with his procedures and when a fire is discovered all employees are expected to take the actions in the acronym of RACE AND PASS	fire/explosive hazard
o undergrounded or wet equipment, frayed cords • possible injury: o burns or shock • since the laboratory setting contains a large amount of electrical equipment which workers have frequent contact the same general rules of electrical safety observed outside the workplace apply • equipment should not be operated with wet hands and the laboratory personnel should continually observe for any dangerous conditions • the equipment and cords must be well-maintained	electrical hazard
• Source: o equipment and radioisotopes • possible injury: o radiation exposure	radioactive hazards
• The chemicals we have this what we call the material safety data sheets in which it contains the informations about the chemicals like physical and chemical characteristics • a fire and explosion potential of a chemical reactivity • potential health hazard and emergency first aid procedures • methods for safe handling and disposal of the chemical • it is a document that contains information on the potential chemical hazards and how to work safely with chemical products	material safety hazard
• source: is the infectious agents or toxins • possible injury: are bacterial, fungal, viral, or parasitic infection • biological hazards- in the healthcare setting provide an abundant source of potentially harmful microorganisms and these microorganisms are frequently present in the specimen received in the clinical laboratory	biological hazards or biohazards
something that has the potential to harm you	hazards
no to low individual and community risk	risk group 1
a pathogen that can cause human or animal disease but is likely to be a serious hazard to the environment. Moderate individual risk, low community risk	risk 2
high individual risk, low community risk a pathogen that usually causes serious human or animal disease but does not ordinarily spread from fone infected individual to another. effective treatment and preventive measures are available	risk 3
high individual and community risk a pathogen that usually causes serious human and animal diseases and that can be readily transmitted from one individual to another. effective and preventive measures not usually available	risk 4
the microbes not known consistently to cause disease in healthy adults and a present minimal potential hazard to laboratory and environment • it is suitable for work involving bible microorganism that are defined and with will characterize trains no not cause diseases in humans • for example non-pathogenic strain of e coli and this level is the most appropriate among undergraduate and secondary educational training and teaching laboratories that requires basic laboratory safety practices safety equipments and facility design that requires basic level of containment	biosafety level 1
