Under what condition can an apprentice assist a licensee?

An apprentice can assist a licensee under the direct supervision of the licensee to ensure that the apprentice is properly guided and trained in safe practices. This direct oversight allows the licensee to provide immediate instruction and correction, which is crucial in settings where safety is paramount, such as fire extinguisher service.

Direct supervision means that the licensee is present and actively overseeing the apprentice's work, ensuring that all procedures are followed correctly and safely. This arrangement not only facilitates the apprentice's learning and skill development but also upholds safety standards during activities that could involve risks, such as handling fire extinguishers.

The other options suggest scenarios that would not provide the necessary oversight required for apprentices. Assisting without supervision could lead to significant safety hazards, as an inexperienced individual might not have the critical knowledge or experience to handle situations appropriately. Limiting the apprentice to only minor tasks or only in emergencies would also not fulfill the training needs crucial for their growth and understanding within the profession.
