They are pretty clearly labeled and when I first got one, it came with a non-needled practice epipen. That’s probably something everyone should be exposed to. The needles come out fast and can do some serious damage and the difference between properly using an epipen or wasting it during an emergency can be life or death.
A lot of this is long-term planning. The short-term (5-year) phase can be seen outlined on page 107 of the draft document on the city hall website.
