ABSTRACT
In 1931, Herbert Heinrich published his theory now commonly known as ‘Heinrich’s Law’ or ‘Heinrich’s Triangle’ which states that for every ‘serious’ workplace injury there are 29 ‘minor injury’ events and 300 ‘no injury’ events, or, as we might call them today, ‘Near Misses’. Heinrich proposed that by identifying and taking action on the ‘no injury’ events, actual injuries could be avoided.
