Which substance is a Schedule B poison?

The correct identification of Schedule B poisons is critical for understanding regulations related to hazardous substances. Among the substances listed, chloroform is recognized as a Schedule B poison due to its toxic effects and potential use in harmful applications.

Chloroform has been historically used as an anesthetic and in laboratory settings, but it poses significant health risks, including the potential for causing serious respiratory and neurological damage upon exposure. Regulations categorize it as a Schedule B poison to ensure that it is handled with care and that proper warnings and controls are in place to protect public health.

In contrast, while other substances such as arsenic, hydrocyanic acid, and lead acetate are indeed toxic and have their own regulatory frameworks, they are not classified under Schedule B in the same way as chloroform. Understanding the specific classifications helps pharmacists and health professionals ensure safe handling and compliance with legal standards for these substances.
