According to API Standard 936, the contractor is explicitly responsible for the quality of the refractory installation work. This responsibility directly includes the creation and maintenance of complete and accurate records of the installation process. The contractor performs the work and is therefore best positioned to document the materials used, procedures followed, personnel involved, and quality control tests performed. The inspector verifies these records, and the owner approves them, but the primary responsibility for their accuracy lies with the contractor.

A. refractory manufacturer: The manufacturer is responsible for the quality of the material supplied and providing installation guidelines, not for documenting the contractor's work.

B. owner: The owner specifies the requirements and is the ultimate recipient and approver of the records but is not responsible for their creation or initial accuracy.

D. inspector: The inspector's role is to verify that the installation and its documentation comply with the specified requirements, not to create the records themselves.
