How many years must emergency/disaster drill documentation be maintained in a facility?

The correct duration for maintaining emergency or disaster drill documentation is typically three years. Keeping this documentation for a period of three years is important for various reasons, including regulatory compliance, ensuring that the facility can demonstrate its preparedness in the event of an actual emergency, and for conducting reviews and improvements to emergency plans based on drill outcomes.

Maintaining records for less than three years could potentially lead to issues in terms of legal liability or preparedness assessments, as well as missing out on valuable insights that could improve future drills and emergency responses. Having three years' worth of documentation allows for a comprehensive overview and historical context that is beneficial for ongoing training and evaluation processes.
