I agree, safety is important. Making decisions regarding the safety of students is very important.
Where am I going with this?
Today I was told that it might not be safe for elementary students to go on a particular field trip due to the location. Now, keep in mind that high school students just went and will probably go again.
So what was questioned was about it being safe for elementary students? I have no idea.
I am pretty sure the location is either safe or unsafe (or uncertain, as is often the case in my current context).
