CETP Pre-Certification Review
Propane has many advantages as a fuel source, including: - ANSWERA. It burns slowly because of its low
pump-octane
B. It is stationary and non-portable
C. It is a clean-burning, non-toxic fuel
D. It leaves a high-residue as it burns
If a service technician is asked to perform a task that he or she is not fully trained or qualified for, the
best action is to: - ANSWERA. Say nothing, gather up his or her tools and supplies, and quietly leave the
site
B. Attempt to perform the task to the best of his or her abilities
C. Promise the customer that he or she will return once trained.
D. Tell the customer that he or she cannot perform the task, but will work on getting a technician who
can
