Explanation
Woven reusable fabrics are not the packaging products of choice for ozone sterilization.

Explanation
Ethylene is not responsible for killing microorganisms through oxidation. Ethylene is a naturally occurring gas that plays a role in the ripening of fruits and vegetables. It does not possess any antimicrobial properties and therefore cannot kill microorganisms through oxidation.

Explanation
The statement is true because ethylene oxide, hydrogen peroxide, and ozone sterilization processes are all effective methods for sterilization. However, these processes can have potential risks and limitations. Therefore, it is necessary to monitor them using chemical, physical, and biological monitors to ensure that the sterilization is effective and safe. These monitors help to verify that the sterilization process has achieved the desired level of sterilization and that there are no residual harmful substances present.

Explanation
Ethylene oxide, hydrogen peroxide, and ozone sterilization cannot all use the same packaging materials. Each sterilization method requires specific packaging materials that are compatible with the sterilization process. Using the wrong packaging materials can result in ineffective sterilization or damage to the packaging. Therefore, it is false to say that these three sterilization methods can use the same packaging materials.

Explanation
The statement is false because lumens should be DRY when using hydrogen peroxide as a sterilizing agent. Moisture can interfere with the effectiveness of hydrogen peroxide in killing microorganisms. Dry lumens ensure that hydrogen peroxide can penetrate and eliminate any potential pathogens effectively.

Explanation
Ethylene oxide is a toxic gas. This means that it can cause harm or even death if inhaled or exposed to for a prolonged period of time. It is commonly used in industrial processes such as sterilizing medical equipment and manufacturing chemicals. Due to its toxicity, proper precautions must be taken when handling ethylene oxide to ensure the safety of workers and the environment. Therefore, the statement "Ethylene oxide is a toxic gas" is true.

Explanation
Cellulose-containing packaging materials are not compatible with hydrogen peroxide sterilization because hydrogen peroxide can react with cellulose, leading to degradation and potential loss of the packaging material's integrity. This can compromise the effectiveness of the sterilization process and potentially contaminate the contents of the package. Therefore, it is true that cellulose-containing packaging materials are not compatible with hydrogen peroxide sterilization.

Explanation
The information about a device's compatibility with a specific sterilization process should be obtained from the device's manufacturer because they have the necessary knowledge and expertise regarding their products. They can provide accurate information about the sterilization methods that can be safely used without causing damage or compromising the device's functionality. Relying on the manufacturer's guidance ensures proper sterilization and avoids any potential risks or issues.

Explanation
An extended aeration cycle is not required for items sterilized in ozone sterilization processes. Ozone sterilization is a process that uses ozone gas to kill microorganisms and disinfect items. It is a relatively quick process and does not require an extended aeration cycle. Therefore, the correct answer is False.

Explanation
Permissible exposure levels for low-temperature sterilization methods are established by the Occupational Safety and Health Administration. This agency is responsible for setting and enforcing workplace safety regulations, including exposure limits for hazardous substances. As low-temperature sterilization methods involve the use of chemicals or gases that may pose health risks to workers, it is the responsibility of the Occupational Safety and Health Administration to establish safe exposure limits to protect employees from potential harm.
