The primary advantage of using UV light for disinfection is that it does not leave chemical residues, making it safe for use in sensitive environments.

The primary disadvantage of glutaraldehyde is its strong odor, which can be unpleasant and may pose health risks to users.

Chlorine-based disinfectants primarily act by denaturing proteins, which disrupts cellular functions.

The primary purpose of using a biological indicator is to verify the effectiveness of the sterilization process by demonstrating that spores have been killed.

Hydrogen peroxide is effective against spores, especially at higher concentrations, making it a suitable disinfectant for various applications.

The color of the disinfectant does not affect its efficacy; however, concentration, organic matter, and temperature do.

Bacillus subtilis spores are commonly used as biological indicators to test the efficacy of sterilization processes.

Boiling water is not a reliable method of sterilization as it does not kill all spores and certain resistant pathogens.

Ethylene oxide gas is effective for sterilizing heat-sensitive instruments as it can penetrate materials without causing damage.
