Propane has many advantages as a fuel source, including: - anSwEr-A. 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: - anSwEr-A. Say nothing, gather up his or her tools and supplies, and
quietly leave the site

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
