Semmelweis first promoted the use of disinfecting agents during surgery, such as the spraying of phenol in the operating room. -FALSE

<h3>What are disinfectants?</h3>
  • In the healthcare industry, a variety of disinfectants are employed either individually or in mixtures (for example, hydrogen peroxide and peracetic acid).
  • Alcohols, chlorine and its derivatives, formaldehydes, glutaraldehydes, ortho-phthalaldehydes, hydrogen peroxide, iodophors, peracetic acid, phenolics, and quaternary ammonium compounds are some of these.
  • These compounds are used in commercial formulations, which are distinct products that need to be registered with the EPA or approved by the FDA.
  • Most of the time, a particular product has a certain application and should be utilised in a particular way.
  • Users should thus carefully study labels to ensure that the right product is chosen for the intended usage and applied effectively.
  • Disinfectants are not interchangeable, and using the wrong concentrations or the wrong ones can cost too much money.
