Individuals training to be certified must be what during inspections?

To achieve certification in portable fire extinguisher inspection, individuals must operate under the direct supervision of a certified person. This requirement ensures that trainees receive accurate guidance and oversight from experienced professionals who can provide valuable insights and corrections during the inspection process. Direct supervision allows the trainee to learn best practices, understand compliance with relevant codes and standards, and develop the necessary hands-on skills in a safe environment. This not only promotes safety but also enhances the trainees’ understanding and confidence in conducting inspections independently in the future.

The other options do not align with established training protocols. For instance, independence or self-training may lead to gaps in knowledge or misunderstandings regarding the inspection processes and safety regulations. Working as part of a team can be beneficial in many contexts, but it does not specifically fulfill the requirement for direct supervision per certification standards. Hence, the emphasis on supervised training is crucial for ensuring comprehensive education and safety in the field.
