I've been eyeing up a mast and since found out its used for tetra, would it be wise to steer well clear? I assume so unless anyone can say otherwise?

there is a nice mask near me but it has CCTV on so won't go near it

I think it would be alright if your rig was clean but If there is Tetra there’s got to be CCTV

On taking a closer look there's CCTV on the mast so that rules it out
