1. safety first; safety comes first
A set phrase used as a motto and guiding principle in workplaces, construction sites, transportation, and other contexts where physical safety is a priority. Functions both as a standalone slogan and as an adverbial modifier meaning 'with safety as the top priority.'

Compound of 安全(あんぜん) ('safety') and 第一(だいいち) ('number one; first priority'). Ubiquitous on Japanese construction sites, factory floors, and in transportation — you will see it on banners, helmets, and signs. The phrase originates from the English 'Safety First' slogan popularized by U.S. Steel in 1906, which was adopted in Japan during the industrial modernization of the early 20th century.
