Where It Comes From
Research labs, hospitals (ophthalmology), and facilities that make biological stains; found as powders or water solutions [2][3].
How You Are Exposed
Handling powders/solutions, dust or splashes, skin contact, or accidental ingestion; patients may receive tiny, short-term amounts during eye procedures [2][3].
Why It Matters
Animal studies show increased tumors with chronic dosing; human evidence is limited. IARC has evaluated it as a cancer hazard; it can also cause eye/skin irritation with acute contact [1][2].
Who Is at Risk
Lab and manufacturing workers, ophthalmic surgical staff, and people cleaning spills or waste; pregnant workers should minimize exposure as a precaution [1][2].
How to Lower Your Exposure
Wear gloves, goggles, and a lab coat; avoid creating dust; work in a fume hood; use closed/pre-filled systems in the OR; clean spills with wet methods; dispose as hazardous waste per policy [2][3].
