8 Basic Requirements

Question 1

What is the primary importance of low-temperature sterilization?

Answer 1

Development and growing use of heat- and moisture-sensitive medical devices

Ethylene oxide (EO) and hydrogen peroxide (H2O2) are commonly used methods.

Question 2

Name the two low-temperature sterilization methods commonly used in healthcare settings.

Answer 2

• Ethylene oxide (EO)
• Hydrogen peroxide (H2O2)

These methods are essential for sterilizing sensitive medical devices.

Question 3

What are the eight basic requirements for any type of low-temperature sterilization system?

Answer 3

• Efficacy
• Safety
• Exposure monitoring
• Sterilization performance monitoring
• Penetration
• Material compatibility
• Adaptability
• Approval

Each requirement must be satisfied to ensure patient and worker safety.

Question 4

Define Sterility Assurance Level (SAL).

Answer 4

The probability of a viable microorganism being present on a device after sterilization

SAL is crucial for determining the effectiveness of sterilization methods.

Question 5

What does Efficacy refer to in low-temperature sterilization?

Answer 5

Capability of providing the minimum-required sterility assurance level (SAL)

It is essential for legal marketing in the U.S. as per FDA regulations.

Question 6

True or false: Safety in low-temperature sterilization means there should be toxic residuals remaining on the packaging or device.

Answer 6

FALSE

Safety requires no toxic residuals after the sterilization cycle.

Question 7

What is the purpose of Exposure Monitoring in low-temperature sterilization?

Answer 7

To ensure concentrations of sterilants in the work area remain within required exposure limits

OSHA has established permissible exposure limits (PELs) for safety.

Question 8

What is a Permissible Exposure Limit (PEL)?

Answer 8

The maximum amount or concentration of a chemical that a worker may be exposed to under OSHA regulations

PELs are crucial for maintaining workplace safety.

Question 9

What does Time-weighted average (TWA) refer to?

Answer 9

The amount of a substance employees can be exposed to over an eight-hour day

TWA is used to express exposure limits.

Question 10

What are the potential health risks associated with ethylene oxide (EO)?

Answer 10

• Toxic residues
• Long aeration times
• Health risks for healthcare workers

Monitoring and precautions are necessary when using EO.

Question 11

What is the role of the National Institute for Occupational Safety and Health (NIOSH) regarding low-temperature sterilants?

Answer 11

Developing standards for immediately dangerous to life or health (IDLH) concentrations

NIOSH sets safety standards to protect workers.
