What is a potential risk when using formaldehyde as a sterilizing agent?

Formaldehyde is widely recognized for its effectiveness as a sterilizing agent, but it carries significant health concerns that make it a potential risk in laboratory settings. The correct choice highlights that formaldehyde is toxic and classified as a carcinogen, meaning that it poses serious health risks to those who may be exposed to it over time. Prolonged inhalation or skin contact can lead to severe adverse effects, including respiratory issues and increased long-term cancer risks.

Understanding this risk is crucial for laboratory personnel because it emphasizes the importance of safety protocols, including the use of personal protective equipment (PPE), proper ventilation, and strict adherence to handling guidelines to minimize exposure. This awareness ensures the safety of all individuals who work in or around environments where formaldehyde is used, underscoring the need to balance its utility in sterilization with the potential health hazards it presents.
