My hometown service is paid per call and only on call status we have no fulltime personnel. Our EMT-B's can do all the basis skills of course, plus, albuterol nebulizer tx, asa admin in chest pain, assist pt. with their own NTG, epi pens, and soon to be intubation. However, being a low call volume service we have mandaory skill maintenance practice to keep our EMT's up to par. So far so good, we have been practicing these things for 3 years now with absolutely no negative repercussions. We have 2 EMT's, myself, a paramedic and one other basic that work professionaly for fulltime services, which helps with passing on helpful tips and advice for performing these skills or procedures. Our medical director is very invovled as well.
