I didn't know that. Did you? I ran across this fact while reading "Popular Science" of all places. This is a very timely subject- in the late summer the weather becomes scorching, sizzling and sweltering in most parts of the USA. And hurricane season has started for coastal states in the south and east. Air conditioning becomes a essential service this time of year, especially for the elderly or for people with pre-existing health conditions.
People can die from heat stroke. In 2017 a total of 12 nursing home residents died from heat stroke - in one nursing home. I repeat - 12 people died from heat stroke during the summer of 2017.
Following this horror in 2017 states began what amounts to a pathetic regulatory response. In some cases a facility may have a generator that is not powerful enough to run the AC. In Florida hundreds of nursing homes did not meet Florida's new regulations before Dorien hit in 2019.
Families with loved ones are well advised to find out if their family member's facility has adequate back up generators. Proper generators are hard wired into the facility's system and go on instantaneously when the electric goes out.
