Biohazard Signs | Clarion safety Systems

Q: "What does a biohazard sign mean?"

"A biohazard sign signifies the actual or potential presence of biological hazards such as blood, other potentially infectious materials, or biohazardous waste. OSHA designates the biological hazard warning for this purpose in 29 CFR 1910.145(e)(4)."

Q: "What color is a biohazard sign?"

"OSHA's Bloodborne Pathogens standard specifies fluorescent orange or orange-red biohazard warning labels with the symbol and lettering in a contrasting color. Facility signs commonly pair the symbol with ANSI Z535 signal word formats."

Q: "Where are biohazard signs required?"

"OSHA requires biohazard warnings on regulated waste containers, refrigerators and freezers containing blood or other potentially infectious materials, and containers used to store, transport or ship those materials. Signs are also used at entrances to areas where biohazardous work is performed."

Biohazard Signs for Storage, Processing, and Disposal Areas

Biohazard signs mark the areas in your facility where biohazardous materials are stored, processed or disposed of. OSHA's accident prevention sign regulation, 29 CFR 1910.145(e)(4), designates the biological hazard warning to signify the actual or potential presence of a biohazard, and the Bloodborne Pathogens standard adds specific labeling requirements wherever blood or other potentially infectious materials are handled. Clarion Safety's biohazard signs pair the internationally recognized biohazard symbol with explanatory text in the latest ANSI Z535.2 formats, so the warning is understood by trained staff, contractors and visitors alike.

What the Biohazard Symbol Means and Where It Is Required

The three-crescent biohazard symbol is standardized internationally as symbol W009 in ISO 7010 and is one of the most recognized safety symbols in the world. Under OSHA's Bloodborne Pathogens standard, 29 CFR 1910.1030(g)(1), biohazard warning labels are required on:

Containers of regulated waste
Refrigerators and freezers containing blood or other potentially infectious materials
Containers used to store, transport or ship blood or other potentially infectious materials

Facility signage extends that same warning to room entrances, work areas and equipment, giving people notice of the hazard before they enter or make contact.

Biohazard Signs Designed for OSHA, ANSI, and ISO Compliance

OSHA specifies that biohazard warning labels be fluorescent orange or orange-red with the symbol and legend in a contrasting color. Clarion's biohazard signs meet these requirements and apply ANSI Z535.2 formatting so the signal word, symbol and message work together. Related categories include health hazard signs and chemical hazard signs for facilities managing multiple exposure risks.
