Whilst WW1 chemical warfare ‘helped’ the development of respirators, the first inception of the respirator that we know today actually dates back to Iraq in the 9th Century. Invented by two brothers it was intended to help workers breath whilst going down into polluted wells. The gas mask that we know today has evolved over the years from these first cumbersome pieces of kit.
We are all familiar with Hi Visibility garments and even use the trendy term HI-VIZ, but do you know where it came from? The very first fluorescent pain was invented in the 1930s in California by two brothers, one of whom was injured when the visibility was reduced where they were working. By creating fluorescent minerals and mixing them with wood varnish this created ‘Day-Glo’. Quickly picked up by the US army they managed to reduce the number of people killed in friendly fire accidents when they applied it to the uniforms.
It was first used in the UK in Scotland in the 1970s when railway workers were given hi-viz garments so that train drivers could see them when working on the tracks, the rest as they say is history.
