Safeguarding. This is the term in the teaching profession for the training and practices of keeping children and staff safe. It's terrible sounding word. I have done the required Safeguarding training at several schools and it covers most of the things you would expect and some you things you wouldn't. Current "best practice" for many expensive schools creates a world where a kindergarten teacher is afraid to hold an upset 4 year olds hand as they walk, incase the child suddenly veers off to see a friend and dislocates an arm. So it's a mixed bag of useful and daft. A large amount of Safeguarding is about keeping teachers safe from situations where they could later be accused of something. All male Kindergarten teachers at my old employer in Hong Kong were excused of having to take any children to the bathroom, so there were some positives.  I was always mindful to follow the training that a teacher should never be alone in closed door classroom with less than 2 children for example. It's a sad statement about our times that this has to be such a prominent concern, but it is.   

My approach to personal "safeguarding" relates to  keeping myself safe from the every teachers worst nightmare scenario where a troubled or confused kid either now or decades into the future make an accusation about a teacher. It's another ugly topic, but innocent teachers do sometimes get falsely accused at great cost. To this end the classroom is equipped with obvious CCTV cameras. They provide audio and video coverage inside and out. The feed is archived to a hard disk. After each 3TB disk is full (about 6 months of classes) a new hard disk will be used and old ones securely archived. This may all sound a bit over the top, but it could also help in any resolving any incident or accident between students. I am happy to discuss my rationale in this area.
