It’s the second serious blaze in less than two months. At least 37 people died in a Miryang hospital when a fire broke out in the emergency room. Scores more were injured, though all 94 seniors from an adjacent nursing home were evacuated safely. The hospital didn’t have a sprinkler system. Officials are still investigating the cause, as many point to a December fitness club fire as further evidence that better safety regulations are needed — like new laws that will make sprinkler systems in nursing homes mandatory by June 30.
