I didn't have my finger in the chainsaw trigger. I was cutting sapplings and briars. After making a swipe with the saw, I took a couple steps while the chain was slowing down but hadn't yet come to a stop. The chainsaw was in my left hand. Next time I'll probably make sure the chain is not moving before taking any steps.
Yes, chaps would definitely be safer.
With regards to safety equipment, sometimes I find certain safety devices "less safe" than not having them. For example, I was using a circular saw, I think, the other day and put on safety goggles. The goggles quickly fogged up making visibility with the saw almost impossible. I ended up chunking the goggles and relied on my regular glasses for eye protection. Safety goggles don't help much if you can't see while using a dangerous tool.
