Which of the following types of medical items requires sterilization?

Medical devices that have contact with sterile body tissues or fluids are considered critical items. These items should be sterile when used because any microbial contamination could result in disease transmission. Such items include surgical instruments, biopsy forceps, and implanted medical devices.

Does treating the work area with disinfectant will kill all forms of microbes?

During production of a drug, all work area surfaces must be disinfected using sterilized disinfectants. Disinfectants destroy all microbes present on a surface. Disinfectants are used to inhibit or destroy pathogens. Disinfection can occur by physical or chemical means.

Which of the following is the preferred method of sterilization for most materials in microbiology?

The laboratory sterilization method of choice in most labs is autoclaving: using pressurized steam to heat the material to be sterilized. This is a very effective method that kills all microbes, spores, and viruses, although, for some specific bugs, especially high temperatures or incubation times are required.

Which is the best method of sterilization?

Classical sterilization techniques using saturated steam under pressure or hot air are the most reliable and should be used whenever possible. Other sterilization methods include filtration, ionizing radiation (gamma and electron-beam radiation), and gas (ethylene oxide, formaldehyde).

What is difference between sterilization and disinfection?

Sterilization describes a process that destroys or eliminates all forms of microbial life and is carried out in health-care facilities by physical or chemical methods. Disinfection describes a process that eliminates many or all pathogenic microorganisms, except bacterial spores, on inanimate objects (Tables 1 and 2).

How many types of sterilization methods are there?

Sterilization can be achieved by a combination of heat, chemicals, irradiation, high pressure and filtration like steam under pressure, dry heat, ultraviolet radiation, gas vapor sterilants, chlorine dioxide gas etc.

What chemical is used for sterilization?

Ethylene Oxide

Which chemical is not used for sterilization?

Uses. Alcohols are not recommended for sterilizing medical and surgical materials principally because they lack sporicidal action and they cannot penetrate protein-rich materials.

Which gas is used for sterilization?

What is the advantage of chemical sterilization?

relatively painless (usually used with sedation) and quick procedure. eliminates risk of complications from anesthesia and surgery. need for post-procedure care and observation is minimal.

What is the disadvantages of sterilization?

Disadvantages. Special handling because of flammability, toxicity. Long sterilization and decontamination time. Potential health hazard; fumes must be monitored.

What is the advantage and disadvantage of formaldehyde?

Formaldehyde is widely used fixative. Its advantages are low cost, simplicity of use and good fixation traits, which are fast tissue penetration, good preservation of morphological structures and compatibility with downstream histological applications. Formaldehyde disadvantages are negative effects on nucleic acids.

What is the primary disadvantage of liquid chemical sterilization?

There are several limitations with liquid chemical sterilization. Although the rinse water is treated to minimize any bioburden, it is not sterile. Because the rinse water is not sterile, devices rinsed with this water cannot be assured to be sterile.

What are the advantages of liquid sterilization?

Benefits of Liquid Chemical Sterilization Liquid chemical sterilization provides a higher level of microbial kill assurance for heat-sensitive medical devices compared to high-level disinfection.

How long is chemical sterilization?

about 4 h and 15 m

What are the limitations of liquid chemical sterilants?

improper instrument cleaning or packaging and sterilizer malfunction. What are the limitations of chemical liquid sterilants. requires 10 hours of contact time; anything less than 10 hours is disinfection, not sterilization.

What is a disadvantage of flash sterilization?

What is a primary disadvantage of flash sterilization? instruments are sterilized while unpackaged, and they are no longer sterile once removed from the sterilizer so cannot be packaged. if the sterilizing agent does not come in contact with the item for the proper time.

How do you sterilize liquids?

The most effictive way to sterilize liquids is to heat them in an autoclave or a pressure cooker. But in some cases-especially for media with at least 10% salt-boiling is sufficient.

Is OSHA’s newer term for material data sheets?

Occupational Safety and Health Administration’s (OSHA) newer term for material data sheets; required for each hazardous chemical in a facility.

What are the 9 categories of MSDS?

• SECTION 1 — PRODUCT IDENTIFICATION AND USE.
• SECTION 2 — HAZARDOUS INGREDIENTS.
• SECTION 3 — PHYSICAL DATA.
• SECTION 4 — FIRE AND EXPLOSION DATA.
• SECTION 5 — REACTIVITY DATA.
• SECTION 6 — TOXICOLOGICAL PROPERTIES.
• SECTION 7 — PREVENTIVE MEASURES.
• SECTION 8 — FIRST AID MEASURES.

Is OSHA’s newer term for material data sheets quizlet?

Terms in this set (20) instruments in packages should remain sterile indefinitely unless an event causes them to become contaminated. OSHA’S newer term for material ate sheets. Safety data sheets are required for each hazardous chemical facility.

What is included on a safety data sheet?

The SDS includes information such as the properties of each chemical; the physical, health, and environmental health hazards; protective measures; and safety precautions for handling, storing, and transporting the chemical.

What is the purpose of a safety data sheet?

Safety Data Sheets (SDSs) are summary documents that provide information about the hazards of a product and advice about safety precautions. SDSs are usually written by the manufacturer or supplier of the product.

How do you read a safety data sheet?

How To Read a Safety Data Sheet (SDS)

1. Section 1 identifies the chemical on the SDS as well as its intended use.
2. Section 2 outlines the hazards of the chemical and appropriate warning information.
3. Section 3 identifies the ingredient(s) of the chemical product identified on the SDS, including impurities and stabilizing additives.

How do you get a safety data sheet?

To obtain SDS, get them from the manufacturer.

1. They may be sent with the chemical order (paper copy or e-mail attachment).
2. Otherwise, go to the manufacturer’s website and download it or request a copy.

What is the difference between MSDS and SDS?

There is no difference between an MSDS and an SDS, as both are generic terms for safety data sheets. A GHS compliant safety data sheet is an SDS but not an MSDS.

How many signal words are there?

There are only two words used as signal words, “Danger” and “Warning.” Within a specific hazard class, “Danger” is used for the more severe hazards and “Warning” is used for the less severe hazards.

How do you know if a chemical is required to have an SDS?

The pictogram on the label is determined by the chemical hazard classification. The simple fact to keep in mind is that if it is a hazardous chemical or product, a safety data sheet will be required. If it is a manufactured product, the odds of an SDS existing may be slim.
