So I'm trying to build a ramp for my driveway as council up a bit when re-doing the road so it's not quite set right. I have an old bike rack that I then started to cut up to make the said ramp, but midway through cutting it, I realized it was galvanized. I'm cutting it up outside and have a fan running pretty close to me already anyway as it's quite warm as it is without using my oxy-torch, so I was just curious if it is safe for me to be cutting the steel with what I currently have set up?
