The situation that almost everyone has experienced in their life is being present when a child is choking. Fortunately, all of these incidents that I’ve witnessed have concluded safely because someone had been trained in infant/child CPR (which includes choking). While safety at work is very important, safety at home means everything.
One last note: PRACTICE FIRE DRILLS AT HOME, TOO!
