Can deviations from the approved plan be made without authorization from the AHJ?

The correct answer is based on the understanding of the role of the Authority Having Jurisdiction (AHJ) in fire protection systems. The AHJ is responsible for enforcing compliance with building codes, fire codes, and the approved plans for fire sprinkler systems. Any deviations from these approved plans typically require explicit authorization from the AHJ to ensure that safety standards and regulations are upheld.

Deviating from an approved plan without such authorization can pose significant safety risks and might lead to non-compliance with legal and safety standards. This can result in issues during inspections, potential liability concerns, and jeopardization of occupant safety. Therefore, it is essential to adhere strictly to the approved plans and seek authorization when modifications are necessary to maintain the integrity and safety of the fire sprinkler system.

Options suggesting that deviations can be made under certain conditions, like emergencies or documentation, might imply a flexibility that does not align with the established protocol for ensuring safety in fire protection installations. In most jurisdictions, even in emergencies, the proper channels must still be followed to authorize necessary changes.
