Which disinfectant type is known for its high toxicity and use in some medical facilities?

Phenolic disinfectants are recognized for their high toxicity and are commonly used in certain medical facilities due to their effectiveness against a wide range of pathogens. They are derived from coal tar and have a strong antimicrobial property, making them suitable for disinfecting non-porous surfaces in environments like hospitals and laboratories where controlling infection is critical.

Their potency, however, means that they must be handled with care, requiring users to follow strict safety protocols, including using gloves and proper ventilation due to potential health risks such as skin irritation and respiratory issues. This high toxicity is a key reason why their use is limited to professional settings rather than personal or non-medical environments.

Other types of disinfectants, such as alcohol-based or chlorine compounds, may also be effective, but they typically do not carry the same level of toxicity as phenolic disinfectants, making them safer options for broader applications. Natural disinfectants, while appealing for their lower toxicity and environmental friendliness, generally lack the strength and efficacy of phenolic disinfectants in high-risk medical situations.
