What should you do if you accidentally ingest a hazardous substance?

Seeking medical attention immediately and notifying the supervisor is the appropriate course of action if you accidentally ingest a hazardous substance. This response is crucial for several reasons. First, hazardous substances can have immediate and serious health effects, and waiting for symptoms to manifest could lead to worsening conditions or complications. Quick medical evaluation ensures that any potential poisoning or health impact can be addressed promptly and effectively.

Additionally, notifying a supervisor is essential for a couple of reasons. Supervisors need to be informed to take necessary action regarding workplace safety and ensure that other employees are not at risk. It also allows for documentation and reporting of the incident according to lab safety protocols, which can be important for compliance and preventing future incidents.

The other options may seem like quick fixes but can lead to more harm than good. For instance, inducing vomiting is generally not recommended for many substances, as it might cause further injury to the esophagus or lungs if the toxic material is aspirated. Drinking water and continuing to work can further expose the individual to dangers or mask symptoms, while waiting for symptoms is neglecting the immediate response needed to ensure safety.
