I would suggest contacting them directly and seeing if you can help facilitate bringing a full ASIST training in. There are often local groups you could partner with that might help bring it in for free. You may need to be an active advocate to get this training, but I really recommend it in your situation. It is intended exactly for you, for first line folks who are already in people's lives with the potential to intervene.
You might check with local police, anti drug coalitions, community mental health clinics, and other religious, social, and community groups to see who might be able to help bring it in. It can be a real benefit to your whole community; there are many others out there who are adjacent to sufferers just like you are.
There are other suicide prevention resources out there, I just speak to this one because I know it. I've been through it, I've put students through it, and those students have successfully intervened in their family and friends' lives, preventing them from completing suicide attempts. Like I have said before, the training is very difficult, intense, but it is literally lifesaving. For myself, it also helps with my anxiety levels to know that, should a situation arise, I am more equipped to deal with it than I was previously.
