This has been a hot week, and it\u2019s likely we will have more just like it before summer is done with us. While it seems like it shouldn\u2019t need saying, inevitably it does. Do not leave anyone, particularly children or elderly people or pets in a closed-up car. Not for five minutes. Not in the shade. Not anywhere, anytime. It doesn\u2019t take much for tragedy to result. So far this summer, police have not had any calls about children or elderly people being left like that. But there have been at least two incidents where people have left their dogs in their cars at supermarkets in town, according to Animal Control Officer Chris Muir. Fortunately, the dogs were OK when he assessed them. He made a point of mentioning, however, that there are signs posted at each supermarket \u2014 Caraluzzi\u2019s, Stop & Shop, and Village Market \u2014 reminding people \u201cheat kills.\u201d Children left in a parked car can suffer heat stroke and possibly die. Dogs pant to cool themselves. Left in a hot car they can overheat rapidly and die. When it\u2019s 70 degrees outside, it can be 120 degrees in a car; and when it\u2019s 80 degrees, it can rise to 150 degrees or 160 degrees, essentially turning the car\u2019s interior into an oven. This week has seen temperatures rise into the 90s, and it\u2019s easy to see how quickly someone could die under those conditions. Tragically, some cases of children killed or injured by being left in a hot car are truly accidents. Parents have a lot on their minds and it is easier than one might think to forget a sleeping child in the back seat. One way to prevent this is to get in the habit of checking the back seat every time you arrive at your destination. It\u2019s called \u201clook before you lock.\u201d One way to do this is to put a cell phone, handbag, briefcase, or employee badge in the back seat with the child to ensure you always open the back door when you get where you are going. Remember, it doesn\u2019t have to feel hot outside to be dangerously hot inside a parked car. If you see a child or pet in a locked car on a warm or hot day, don\u2019t hesitate to call 911. The coronavirus pandemic has added an unfortunate twist to a heatwave. Because the library and town buildings are closed, and swimming at Merwin Meadows is discouraged, there are no public places to cool off. That leaves staying indoors \u2014 which many of us have probably had enough of \u2014 to stay safe. It may be a worn-out clich\u00e9, but better safe than sorry.
