What is the first action to take if radium powder is spilled in a laboratory?

In the event of a radium powder spill, prioritizing safety and following proper protocol is crucial. The first action should focus on ensuring the safety of personnel and preventing potential exposure to the radioactive material. Evacuating personnel and rerouting traffic minimizes the risk of contamination and protects individuals from possible radiation exposure.

Addressing the safety of all individuals in the vicinity takes precedence, as radium is a radioactive substance that poses significant health risks. Once personnel are evacuated and traffic is rerouted, appropriate trained responders can then assess the spill and determine the best method for containment and cleanup, following established safety procedures. This approach prioritizes public health and safety, adhering to regulatory standards for handling hazardous materials.
