What is the primary reason experts must stay current according to NFPA 1033?

The primary reason experts must stay current according to NFPA 1033 is to stay informed of advances in fire science. Fire investigation techniques, technology, and understanding of fire behavior and dynamics continuously evolve due to new research, case studies, and technological advancements. Staying updated with these developments is crucial for fire investigators, as it enables them to apply the most effective methods and understand the latest scientific principles in their work. This knowledge not only enhances the accuracy of investigations but also ensures that investigators are equipped to address new challenges and complexities that may arise in fire cases.

While maintaining certification, understanding changing laws, and improving investigative techniques are also important, they serve as secondary motives compared to the foundational necessity of being informed about the latest advances in fire science, which impacts every aspect of fire investigation.
