Personally I applaud the intent of the person wanting to know what to do and willing to take the time to learn the skills. But, a well taught industrial first aid class will probably give them as many tools as will be usable to them as an EMT class in a lot less time, with a lot less expense.
For California the cost may not be less than the EMT-B done at a CC. Community College credit hours are only about $20 - $22.00/cr. If EMT-B is about 12 credit hours, that's fairly reasonable although the book will be expensive. Of course, if a crash class from a career college is done it will be more expensive.
Through the Orange County ARC:
Adult CPR and AED - 5 hours $55
Child, Infant CPR 5.5 hours $45
Basic First Aid 4 hours $45
Advanced First Aid 54 hours $200
Water Safety 2 hours $25
Bloodborne Pathogens - 1 hour $20
Add that to attempting to schedule all the classes you want and it might work or not.
