Yes, absolutely less dangerous than lead used in house paints. I don't actually know about the situation in Europe in general, but e.g. Sweden prohibited lead paint for indoor use already in 1860, and France in prohibited lead-based indoor and outdoor house paints in 1909. Based on some quick googling it seems several European countries prohibited lead-based house paints (including outdoor paints) in the 1920'ies.
