Private entities need an ATF Explosives License. Government entities do not. A simple example: Let’s say two schools want to purchase display fireworks. One is a private school. The other is a public school. The private school needs an ATF Explosives License because it’s privately owned. The public school does not, as it is a government entity. AFT has made government entities exempt from the licensing requirements.
If you are wondering about “Volunteer Fire Departments,” they are also considered to be government entities, even though some may be privately funded. However, we need to get all the proper paperwork filled out and the checks must come directly from the fire department.
