Most tools and Implements can be disinfected. These include combs, brushes, rollers, picks, styling tools, scissors, tweezers, nail clippers, and some nail files.
Critical medical items that come into contact with sterile tissues, such as surgical instruments and catheters, require sterilization. Semicritical items, like gastrointestinal endoscopes and equipment for respiratory therapies, require a high level of disinfection.
Rubbing alcohol has proven to be pretty effective but problematic because of flammability and cost effectiveness. Pine-Sol, Lysol and chlorine bleach have the best track record in true disinfection.
If the item is nonporous, such as hard plastics, metal, or glass, it can typically be disinfected. It's much more challenging to disinfect items like upholstery, fabrics, or even wood. To treat those, we use specialized equipment and cleaning methods.
Disinfection is for hard, non-porous surfaces—typically, items made of glass, metal, or plastic or referred to as synthetic materials. Porous/soft surfaces cannot be disinfected, but can be cleaned. This would include items such as towels, chairs covered in a porous material, and your hands and body.
Soak in alcohol for a whole day. After soaking, pour the chemicals off and let the tools dry. Move them directly to a disinfected container with a lid using disinfected tongs. Remember, anything you touch with your hands is no longer disinfected.
Sterilization kills or renders inactive all microbial organisms. The common methods used are steam heat, ethylene oxide gas or chemicals. Any item used for survival surgery, ie. instruments, catheters, flow probes, or electrodes and fluids used for flushing or injection must be sterilized.
Final answer: The correct answer is c. spray.
Methods of sterilization that can be used for critical or semicritical dental instruments and materials that are heat-stable include steam under pressure (autoclave), chemical (formaldehyde) vapor, and dry heat (e.g., 320ºF for 2 hours).
One of the easiest ways to sanitize pruning equipment is to use ethanol or isopropyl alcohol. To sanitize with alcohol, wipe or dip the tool into the alcohol. No prolonged soak is needed.
Key steps:
Clean your kitchen utensils in hot water with an antibacterial detergent. When sanitizing kitchen tools and equipment, use either boiling water or a solution of bleach and water. Store your tools in a regularly cleaned plastic or metal box to keep the germs away.
Disinfection is a process of inactivating pathogenic organisms except for bacterial spores. Sterilization is the elimination of all viable microorganisms. Single-use medical devices resolve the difficulties of reuse and decontamination procedures and should be used where appropriate.
The most commonly used FDA approved LCGs for disinfection of flexible endoscopes include glutaraldehyde, ortho-phthalaldehyde (OPA), peracetic acid, and hydrogen peroxide (Table 4.1 )71, 80, 81 based chemicals in varying combinations and concentrations.
Cleaning alone removes most harmful viruses or bacteria from surfaces. Surfaces should be cleaned before they are sanitized or disinfected because impurities like dirt may make it harder for chemicals to get to and kill germs. Sanitizing reduces the remaining germs on surfaces after cleaning.
Before using any sterile equipment check that:
the packaging is intact. there are no obvious signs of packaging contamination. the expiry date remains valid. any sterility indicators are consistent with the process being completed successfully.
o DO NOT AUTOCLAVE SEALED CONTAINERS OR BAGS.
PROHIBITED ITEMS: Autoclaves must not be used with the following: ▪ Corrosives (e.g., acids, bases, phenol, etc.), solvents (e.g., ethanol, methanol, chloroform), or radioactive materials: Contact EHS or review the EHS Program Manual, Section 5.2 - Waste Disposal Procedures for proper decontamination and disposal ...
For all nonstandard sterilization techniques, gross contamination should be removed from all instruments/equipment by scrubbing with soap and water first. Chemical sterilization elements should never be combined. Steam with distilled water is the preferred sterilization technique.
You can wipe down tweezers and manicure tools with hydrogen peroxide to remove dirt and germs.
To help stop the spread of COVID-19, workers who use shared tools should clean those tools each shift before they use the tools. Those who sanitize these tools should wash their hands or use proper hand sanitizer prior to starting the cleaning.
