An Aseptic
Aseptic processing
Aseptic processing is the process by which a sterile (aseptic) product (typically food or pharmaceutical) is packaged in a sterile container in a way that maintains sterility.
Asepsis
Asepsis is the state of being free from disease-causing contaminants (such as bacteria, viruses, fungi, and parasites) or, preventing contact with microorganisms.

What is an aseptic technique?
According to the organization EngenderHealth, aseptic techniques are those which: remove or kill microorganisms from hands and objects; employ sterile instruments and other items; reduce patients’ risk of exposure to microorganisms that cannot be removed.
What is the fourth component of aseptic technique?
A fourth component of aseptic technique is surgical prep. The warm, moist conditions inside surgical gloves provide an ideal environment for the rapid growth of microorganisms, so scrubbing with antiseptics before beginning surgical procedures will help prevent this rapid growth of microorganisms for a period of time and will reduce the risk of infections to the patient if the gloves develop holes, tears, or nicks during surgery.
What is the importance of wearing proper PPE during aseptic surgery?
Along with the other elements of aseptic technique, proper surgical attire helps reduce the risk of post-procedure infections by decreasing the likelihood that microorganisms will enter areas of the patient’s body during procedures.

What is an aseptic field?
An aseptic field is a designated work space that contains and protects procedural equipment from becoming contaminated. There are three types of aseptic fields. They are used in different situations and require different management. The choice of aseptic field should be made to ensure protection of key parts and sites.
Why is critical aseptic field important?
A critical aseptic field ensures asepsis during procedures. It is used when key parts or key sites cannot be easily protected from contamination during a procedure. This may be because the key parts or key sites: can’t be protected by caps and covers. can’t be handled with non touch technique at all times.

What is the cause of preventable infections?
It is widely accepted that poor standards of aseptic technique are a major cause of preventable infections. Healthcare-associated infection is defined by The Association for Safe Aseptic Practice as an infection acquired by a patient as a consequence of exposure to pathogenic organisms via healthcare staff or healthcare facilities 9). In the European Union and European Economic Area it has been estimated that approximately 3.2 million patients per year will have at least one healthcare-associated infection 10). The Centers for Disease Control and Prevention (CDC) reports research indicating that healthcare providers and practitioners taking specific targeted steps can reduce some healthcare-associated infection (e.g. central-line associated bloodstream infections) by more than 70% 11).

What is a septic reserve area?
The land area that is set aside for the septic drain field may be called a septic reserve area (SRA). Sewage farms similarly dispose of wastewater through a series of ditches and lagoons (often with little or no pre-treatment). These are more often found in arid countries as the waterflow on the surface allows for irrigation (and fertilization) ...
What is a septic drain field?
Septic drain fields, also called leach fields or leach drains, are subsurface wastewater disposal facilities used to remove contaminants and impurities from the liquid that emerges after anaerobic digestion in a septic tank. Organic materials in the liquid are catabolized by a microbial ecosystem.
What factors reduce percolation rates when the drain field receives anoxic septic tank effluent?
Several factors may reduce observed percolation rates when the drain field receives anoxic septic tank effluent: Microbial colonies catabolizing soluble organic compounds from the septic tank effluent will adhere to soil particles and reduce the interstitial area available for water flow between soil particles.
What type of soil can be used to filter out pathogens?
Coarse soils – sand and gravel – can transmit wastewater away from the drain field before pathogens are destroyed. Silt and clay effectively filter out pathogens but allow very limited wastewater flow rates. Percolation tests measure the rate at which clean water disperses through a disposal trench into the soil.
What particles can be carried through a septic tank?
Insoluble particles small enough to be carried through the septic tank will accumulate at the soil interface of the disposal trench; non-biodegradable particles like synthetic fiber lint from laundry, mineral soil from washing, or bone and eggshell fragments from garbage disposals will remain to fill interstitial areas formerly available for water flow out of the trench.
How to determine leach field size?
A more progressive way to determine leach field sizing is by direct observation of the soil profile. In this observation, the engineer evaluates many features of the soil such as texture, structure, consistency, pores/roots, etc.
Why does effluent rise in the vicinity of a drain field?
Effluent levels in the vicinity of the drain field will rise toward the ground surface to preserve that vertical distance difference if groundwater levels surrounding the drain field approach the level of effluent in the disposal trench. Frozen ground may seasonally reduce the cross-sectional area available for flow or evaporation.
