Talk:Life net

How can the life net have been invented in 1887 when an ordinance in Göreborg, Sweden, prescribed them already in 1748? See https://sv.wikipedia.org/wiki/G%C3%B6teborgs_brandf%C3%B6rsvar, the Swedish name is "brandsegel". — Preceding unsigned comment added by 2603:3020:EA6:4000:9511:EFDD:6B31:57E1 (talk) 21:25, 16 March 2019 (UTC)
