There are many more nuances that could be added to make the list more complete, but I believe this encompasses the essence of a professional in health and safety.
I believe the Board of Certified Safety Professionals (BCSP) and the American Board of Industrial Hygiene (ABIH) have a similar definition of what it means to be a professional. The strongest tool they have of making this assessment is through their comprehensive exams for the Certified Saftey Professional (CSP) and the Certified Industrial Hygienists (CIH). They make an effort to go beyond just asking questions which merely ask for a regurgitation of facts and try to require the candidates to apply their knowledge. It is a difficult task to create good test questions requiring the application of knowledge in an analytical format, and it is also difficult for examinees to prepare for these types of questions. However, I believe these are an integral part of the certification process.
Occasionally, there are folks preparing to take the exam that seem to "only want to know how to pass the exam" and have no interest in further developing their knowledge base and analytical skills. I am left to wonder if these folks are really ready to become health and safety professionals in the broadest sense of the word.
I believe the mark of a true professional is one who continually thinks about their profession and looks for ways to deepen their understanding. I beleive this to be true regardless of whether the person holds the title of CIH or CSP.
