Sometimes when I'm at work I feel like hvac is part serious work, part gameshow.
1. Walk across the wobbly 2x6 that is held up by wire tied to a drain pipe
2. While on wobbly board avoid falling 40ft into the pit of doom.
3. Don't look down while climbing through hole above the pit of doom because you'll be stabbed by sharp screws.
4. If you it made through that don't relax because it's a rubber roof and when wet or if you stumble there is a built in slip n' slide of death as you come out onto the roof.
