Final answer:
Qualified persons need to be trained in the use of modern engineering tools, have a degree in a technical field and relevant work experience or certification, along with strong communication skills.
Step-by-step explanation:
Qualified persons must, at a minimum, be trained in and familiar with an ability to use the techniques, skills, and modern engineering tools necessary for engineering practice. This includes having a degree in a technical field such as mechanical engineering, physics, chemistry, or polymer/materials science, and a certain amount of related work experience or formal technical training/certification. Additionally, possessing strong communication skills is essential to initiate, establish, and maintain positive relationships within both internal and external environments.
For students following Essential Skills 1, it is crucial to be familiar with the topics covered in Section 1.8 "Essential Skills 1" before tackling numerical problems which likely involve applied skills in a technical or engineering context.
