Is infrared safe? Yes, completely. Is it a “gun pointed at the head”? My opinion? I’ve never heard of it referred to as a temperature “gun.” If that’s what you think it is, then request that the school check another body part, like the inner wrist or inner elbow. Then again, I’d not want a gun pointed at any part of my child’s anatomy. Is this a public school? Catholic school?
Although I’m a teacher, if I had any children of my own, they’d be homeschooling, non-negotiable. When parents ask me, this is what I’ve been saying since 2012.
