“Have you had the laser safety briefing?” a man in a hi-vis vest asks me. Having arrived late and flustered, I’m certain I’ve misheard, so I ask him to repeat the question. “The laser safety briefing,” he says, the words clear as day. “Follow me.”
We walk across a concrete floor into an office, where he hands me a document in a plastic sleeve. Immediately, my eyes are drawn to the blood red warning symbols, and a set of very important instructions; the laser I will come across today is a ‘level four’, and I absolutely must not look at it without tinted, wraparound glasses, a pair of which has just been thrust into my hands.
