This environment is almost certainly fatal, due to Oxygen Toxicity:
When the exposure to oxygen above 0.5 bar (50 kPa) is intermittent, it permits the lungs to recover and delays the onset of toxicity.
0.5 bar would be your 50% O2 level at atmospheric pressures, so current medical knowledge says exposure to this environment must be intermittent.
Oxygen toxicity occurs at points above 0.3 bar (30% at 1atm). It's more trouble as one progresses to higher levels, but that shows that such high oxygen levels are going to cause problems.

Thank you, do you think if I lessened the atmospheric pressures or increased elevation that this would improve survival conditions?

Decreasing would help, but you'd have to decrease it quite a lot. If you dropped the atmosphere to a little above half of our atmosphere, you could get the O2 levels low enough to be safe.

Even if the toxicity didn't do them in, this atmosphere would turn a small firecracker into a grenade. Higher concentrations of oxygen make things burn and/or explode more intensely.
Don't believe just because I'm saying this. Watch this video (you may jump to 0:50).
Humans are dumb, and explosions are a recurring theme in the Darwin Awards. Any large group of people wouldn't survive in that atmosphere even if they were breathing an Earth-like mix of gases from a scuba gear.

If 3% traces are not a problem. Then the only thing that rises concern is an oxygen levels. Oxygen toxicity, as stated, will be part of your problems, as there are more, like production of oxygen species, sight defects and blindness in infants and more.
- Oxygen at 50% is around levels that have no prominent toxicity for humans. So any healthy adult human will be able to live in such an atmosphere.
- Such levels will be a problem for the weaker ones: children, elderly, sick. Your population will age faster and live less, your child mortality and birth defects most likely will push them to extinction.
Good options are:
- We live high. With altitude there is less air, so less oxygen partial pressure. Living 4000 m - will deal with most of problems, around 6000 meters will be Earth like. Do not forget your pressure cooker.
- Balance atmosphere pressure and composition. You would like your oxygen partial pressure to be less than 30 kPa.
Of note such an atmosphere is a fire hazard and promotes corrosion.
