Greg,
That worries me somewhat, because there aren't a lot of accidents at work that will injure you as badly as a fall from height, especially if you fall on your head.

I've done a lot of lines rescue stuff with the NZ fire service here when people get themselves into trouble in various places, but it's sort of like when people are at work, they use the cheapest available harnesses and never get them inspected, so things wear out and when someone does have a fall, the harness breaks it's stitching.

The old "she'll be right" attitude really needs to be turned around.
