How it's used
Safety helmets are specifically associated with industrial or construction environments, distinguishing them from the headgear worn by motorcyclists. While the term is standard, workers often use the more colloquial term 頭盔 when the context of construction is already clear. The color of the helmet often indicates the specific role or seniority of the worker on a site, such as engineers versus general laborers.

Common mistake
Learners sometimes confuse this with the general word for any helmet, 頭盔. Using 安全帽 for a motorcycle helmet sounds unnatural, as that is strictly referred to as a 電單車頭盔 or simply 頭盔.
