There are no doubts that first-aid-training/ can and will save lives, hence the necessity of a little education. It makes no difference if you work in a risky environment or you are self employed at home. Unexpected problems can always arise when least expected. What happens if your kid gets burned in a second of inattention? What if a loved one suffers from asthma? How about diabetes or a head injury? Do you know what to do if such issues arise? Unfortunately, a lot of people have no clue what to do before emergency help comes, yet such things can be fatal.
