Workers' compensation is a fairly new thing, dating only back to the Labour Movement in the early 1900s. Before that, injuries on the job were usually treated with either indifference or cheap payoff — after all, the average factory worker was making mere cents a day, so half a year's pay was chump change for large companies.
But with worker rights came worker safety. And the problem of how to communicate it, if not every worker was literate. Vivid, often gruesome posters depicting the worst case scenario — electrocution, carbon monoxide poisoning, chopping of your thumb, etc — became the norm. A recent post on the illustration blog, 50 Watts, unearthed some excellent examples culled from a Dutch history archive.
It's fascinating to see how styles changed as graphic design evolved. In the '20s and '30s, chemicals and electricity were anthropomorphised as literal monsters, ghouls and animals. But as the Bauhaus ethos and Swiss design entered the picture, danger became an abstract figure — a series of colours, typefaces and symbols arranged artfully on the page. Wonder which approach was more effective?
