Inspection reports for door, shutter, and window assemblies must be retained for what minimum length of time?

The requirement to retain inspection reports for door, shutter, and window assemblies for a minimum of three years is grounded in the need for maintaining accurate records that can facilitate compliance, accountability, and safety oversight. Retaining these reports for this duration allows fire inspectors, building officials, and other regulatory entities to have a historical reference for inspections done, which can be critical for tracking the performance and maintenance of these assemblies over time.

Having such records ensures that there is adequate documentation to support any inspections, testing, or repairs that may have been conducted. This can also help in identifying trends in failures or code violations, thus contributing to overall fire safety and prevention strategies. In summary, three years provides a balance between record-keeping effectiveness and the practical resources available for storage and retrieval of these documents.
