OSHA Biohazard Labeling Requirements & Compliance

Biohazard signage should clearly identify areas, containers, equipment, or materials that present biological hazards. In general, signs should use the recognized biohazard symbol, a strong signal word or warning message, and durable materials suited to the environment. Placement should be visible before exposure occurs, such as entrances, storage areas, waste containers, or equipment zones where biohazard risks are present.

OSHA requires biohazard labels to warn employees of potential exposure to infectious materials or regulated waste. Labels commonly need the fluorescent orange or orange-red background, contrasting lettering or symbols, and the universal biohazard symbol. They should be attached to containers, refrigerators, freezers, waste bags, contaminated equipment, or other items where exposure risks exist under applicable OSHA standards.

For hazardous chemicals, OSHA’s Hazard Communication Standard generally requires labels to include a product identifier, signal word, hazard statements, pictograms, precautionary statements, and supplier identification. These elements align with GHS labeling principles. Facilities should ensure labels remain legible, are not removed or defaced, and accurately communicate the specific hazards associated with the chemical.

Acceptable biohazard labels are typically durable, highly visible, and easy to recognize. They should include the universal biohazard symbol and use OSHA-recognized color conventions, such as fluorescent orange or orange-red with contrasting text. Labels may be preprinted or produced on demand with an industrial label printer, provided they remain legible and appropriate for the surface and environment.

Yes, many facilities print their own biohazard labels using industrial label printers and compliant design templates. The key is ensuring labels include the required visual elements, remain legible, and are made from materials suited to the environment. Shield and Supply’s LabelTac® printers and LabelSuite™ software help teams produce consistent labels for ongoing OSHA compliance projects.

Biohazard labels should be placed wherever employees may encounter regulated waste, potentially infectious materials, contaminated equipment, or storage areas containing biological hazards. Common locations include containers, bags, refrigerators, freezers, laboratory entrances, equipment awaiting decontamination, and transport containers. Labels should be positioned where they are visible before handling, opening, or entering the affected area.

Biohazard labels should remain readable for as long as the hazard is present. In industrial or healthcare-adjacent environments, labels may need to withstand handling, moisture, cleaning, temperature changes, and abrasion. Using industrial-grade supplies helps reduce peeling, fading, or smearing, especially on containers, equipment, or facility surfaces that are frequently moved, cleaned, or exposed to demanding conditions.

Shield and Supply provides free support by phone, email, or live chat to help customers choose labeling systems, supplies, and resources for safety and compliance projects. The company also offers safety resource guides for topics such as GHS, pipe marking, floor marking, arc flash labeling, barcoding, and 5S to help teams plan more effective labeling programs.
