Be sure that you have laid down a sufficient foundation first though. Then start out very light and work your way back up. You should be able to blow past former singles maximums. Form has to be perfected first, and you have to stay very tight. If you miss your top single, stop for that workout.
Singles are safe.
Form is unusually good with a single because of not being exhausted from the previous 9 of a set of 10. In my experience, that is when I have seen injuries crop up. When performing that top single you are very fresh as long as you used a smart warmup protocol. Use warmups, not wear-outs.
