Day 1

I'm working at the Scottish Fire Training College at Gullane for the next three days.
I love it here, the team are so supportive and value everything we do for them.
Took the chance to peruse the scenery whilst it was snowing, thinking each time, "what will I blip today. ?.."

So what is this?
What do I do with this at a college full of fire fighters?
Clue: They get one each and use it anything between five and thirteen times in 10mins!

I look forward to your answers!!
