☣️ biohazard Emoji — Meaning, Copy & Paste

What Does the biohazard Emoji ☣️ Mean?

A black biohazard symbol on a yellow background — the international warning for biological threats. Available since Unicode 1.0 / 5.2 (2010), the biohazard emoji is used for biological hazard warnings, lab safety, pandemic content (massive surge during COVID-19), and infectious disease discussions. Healthcare workers, scientists, and biosafety educators use it.

Resident Evil, The Last of Us, and zombie content feature it heavily. It also gets metaphorical use — 'this fridge is a biohazard ☣️,' 'frat house bathroom ☣️,' or 'my room after finals ☣️' — for anything dirty, dangerous, or contagious-feeling. Goth, industrial, and rave aesthetic communities love it.

Whether you're posting about lab work, joking about a messy roommate, or sharing zombie game content, this symbol radiates danger and intrigue. The most striking warning icon on the emoji keyboard. The Walking Dead, The Last of Us, and 28 Days Later fan accounts use it heavily.

Public health communicators have also leaned on it harder since 2020, even for less catastrophic illness reminders too.
