What is the first step to take when encountering a clandestine lab?

When encountering a clandestine lab, the first step is to exit immediately and secure the scene. This action is critical for ensuring personal safety and the safety of others in the vicinity. Clandestine labs often involve hazardous materials and dangerous processes that can pose significant health and safety risks, including exposure to toxic chemicals or potential explosions.

By exiting and securing the scene, you prevent further exposure and allow trained professionals, such as law enforcement or hazardous materials teams, to assess and manage the situation safely. This approach prioritizes safety over investigation or documentation, which should only be performed by authorized personnel equipped to handle such environments.
