It is interesting how the very things that make us safer can sometimes make life more difficult for someone trying to rescue us in an emergency. The trend toward school lock-downs to protect kids makes it more difficult for law enforcement officers to safely find a gunman hiding in the building. The design decisions that make cars safer, like the Nader pin that keeps doors from swinging open in a crash, also make them harder to get into in order to remove someone from a smashed vehicle.
So often the trade-offs are between opposing benefits, like cost vs longevity or efficiency vs safety: the air-tight nature of energy-efficient new home construction increases smoke damage in a fire, and material-efficient engineered joists increase the danger of a floor collapsing during a fire. It isn't so often than the trade-offs are both held within one benefit, safety vs safety.
