Who is responsible for verifying sprinkler systems are adequate for what is being stored in the building?

The responsibility for verifying that sprinkler systems are adequate for what is being stored in a building primarily falls on the building owner. This is because building owners are accountable for the safety and compliance of their property, including ensuring that the fire protection systems meet the specific requirements of the materials being stored.

Building owners need to consult with fire protection professionals to assess the hazards associated with the stored materials and confirm that the sprinkler system is appropriately designed and installed to mitigate those risks. This includes factors such as the type of materials, their quantities, and any special considerations like flammable or hazardous substances, which could necessitate a more advanced sprinkler system.

While sprinkler fitters and contractors play crucial roles in the installation and maintenance of these systems, the ultimate responsibility for ensuring that the systems are appropriate for the building's use rests with the owner. Additionally, occupants are more focused on day-to-day operations and may not have the knowledge or obligation to make those assessments.
