There was a time when I was on NCS (national citizen service) and we were adventure training. I was stood on top of a cliff in the middle of the sea, I was terrified of heights, but they expected me to jump off. Instead of thinking about the height, I studied the risks involved and did a mini risk assessment of where would be safest to jump and I just throw myself off and I did it. I was very proud of myself.
COSHH stands for Control of substances hazardous to health. It is about chemicals and knowing whether PPE is needed (personal protective equipment i.e. gloves, eyewear etc.) whether the chemical is irritant, explosive, harmful, toxic etc and where to store them safely.
