What initial steps must a contractor take for applicator qualification testing?

The correct approach for applicator qualification testing involves practical demonstration at the job site, as it is crucial for showcasing the contractor's ability to properly apply the refractory materials in the actual environment where they will be used. This on-site demonstration provides a real-world context for assessing the applicator's skills, ensuring they meet the necessary standards and requirements of the job.

This step also allows for immediate evaluation of the applicator’s techniques and methods in a setting that reflects the conditions under which the material will be installed. It adds an important layer of verification that cannot be achieved through more abstract methods, such as reviewing reports or conducting remote assessments.

Performing all testing remotely does not provide the same level of insight into the applicator's capabilities or the behavior of the materials under job site conditions. Additionally, hiring external personnel might not be necessary or appropriate, as the focus should ideally be on the current team gaining hands-on experience. Preparing detailed reports about test materials can support the qualifications process but does not serve as an initial step for testing the applicator’s skills directly.
