Which of the following tasks is performed after laboratory decontamination?

After laboratory decontamination, it is crucial to document compliance with safety standards. This documentation serves several important purposes: it provides a formal record that decontamination procedures were followed correctly, helps in maintaining accountability, and ensures that all safety protocols have been adhered to before the laboratory is deemed safe for use again. It establishes that the laboratory meets the necessary safety regulations and can be a vital part of an organization's safety management system.

Final inspections of hazardous materials and shutting down all laboratory systems are important steps in the safety protocol but are typically part of the processes leading to decontamination or done concurrently. The act of documenting compliance, however, specifically follows decontamination to verify that the environment is safe and ready for further use or inspection.
