Medium risk for example bedpans, urinals, commodes. High risk for example, instruments used for invasive techniques. Once the risk has been identified, the type of cleaning needed can be carried out. For example , needles used will be high risk and will need to be sterilized. 2.6 The level of risk determines the type of agent that may be used to decontaminate as there are agents for different risks, low risk is water and detergent" medium risk is disinfectants and high risk is sterilizing agents.
Clinical microbiology MLT1 Task 9 Antibiotic Sensitivity Chandra Evans A) Selectively Toxic is defined by the fact that the antimicrobial treatment used, destroys selective microorganisms, but doesn’t harm the host. Selective toxicity of an agent is necessary so that during treatment the agent will not affect or interact with the normal functioning microorganisms in the host. The agent will interact with microbial structures and functions that are not the same as the microbial structures of the host. B) Broad spectrum antimicrobials are effective against a large range of both Gram-negative and Gram-positive microorganisms A pro of this type of agent is the fact that a variety of bacteria is targeted at the same time when used. A con is the higher risk of destruction of normal body flora.
Haz Mat- Any substance or material could adversely affect the safety of the public, handlers or carriers during transportation. 1001- Acetylene; Extremely flammable gas and is unstable. as a precaution isolate the spill for at least a 100meters in all directions, and evacuate in a large spill or fire. First aide move victim to fresh air, give artificial respiration, administer o2, remove contaminated clothing. If contact was liquefied gas thaw the frozen parts with lukewarm water.
Be sure to remove all material so that tubers can not regenerate. - All chemicals signed for daily including area of use, rates, amount used, weather conditions. PPE signed for and worn. 2. Contamination precautions - use weed wand lid to prevent spills and herbicide contact with non target plants and waterway - cleaning of clothing and equipment to stop poisoning of non target species and stop spread of CCC - removal of unwanted cut plant material 3.
When sterilisation is complete do not open the autoclave until the steam has been exhausted and the temp has fallen. If the steam escapes it will rise up and the operator will get burnt. Cleaning surgery tables with trigene or domestos- irritation to eyes and skin very dangerous if swallowed. Inhalation of chemicals. Wear PPE.
Clinical waste should always be put into an orange clinical waste bag. Clinical waste is disposed either by yellow stream waste or by disinfections prior to landfill which is orange stream. Anything that might cause offence or distress if seen on a landfill site, such as a recognisable body part, or is highly infectious needs to be disposed of by yellow stream waste. (Under the Controlled Waste Regulations 1992) Health and Safety Commission, and the Environment Agency gives advise and guidance for disposing of clinical waste. (Waste Online 1999) Household waste is domestic items such as paper, flowers, plastic bottles which are not contaminated so are not at risk of spreading infection.
1.2 Describe how breaking the chain of infection minimizes the spread of infection. Breaking the chain of infection by targeting one or more links can prevent the spread of infection. This usually involves: Eradicating the source of infection through appropriate antimicrobial therapy; preventing the method of spread through infection prevention and control measures; * such as hand and personal hygiene; * use of Personal Protective Equipment ; * environmental cleaning; * decontamination of equipment; * Disposal of waste. Protecting the individual at risk by immunization; Preventing microorganisms from entering the body by: * wearing protective clothing; * using an aseptic technique when handling invasive devices or dressing wounds; * Covering wounds and insertion sites with sterile dressings etc. It will not be possible to identify all service users who have an infection.
3. Describe how the correct management of the environment minimise the spread of infection, Correct management of the environment minimise the spread of infection. Make sure all the staff should be fully trained in infection control and waste management. Uhl provides e learning infection control which is helpful. Cleanliness of the environment prevent spread of infection.
The different uses will depend on the food being irradiated as each technology has strengths and weaknesses. Gamma ray irradiation is very powerful and can penetrate substances deeply. It also yields substantial uniformity of the does in the product and decays to non-radioactive nickel. But the radioactive source, commonly Cesium-137, requires frequent replenishment and treatment of the food is relatively slow. Additionally, protective barriers must be in place when this form is used to protect workers and the environment.
Some observers believe that self-replicating itself should be strictly banned as the only way to fend off the threat of some engineered molecular system running rampant (Brown, 2004). They also can lead to the accidental or deliberate creation of pathogenic biological components (Brown, 2004). Molecular engineering is any means of manufacturing molecules. It may be used to create, on an extremely small scale, most typically one at a time, new molecules which may not exist in nature, or be stable beyond a very narrow range of conditions. this is an extremely difficult process, requiring manual manipulation of molecules using such devices as a scanning
