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.'
安全第一で作業する。
To work with safety as the top priority.
工事現場には「安全第一」の看板がある。
There is a 'Safety First' sign at the construction site.
台風が近づいているので、安全第一で行動してください。
A typhoon is approaching, so please act with safety as your top priority.
Compound of 安全 ('safety') and 第一 ('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.
