Cancer Hazard Signs

For many designated carcinogens, OSHA mandates the specific text "DANGER: CANCER HAZARD - AUTHORIZED PERSONNEL ONLY." Depending on the substance, additional warnings like "Respirators Required in This Area" may also be legally required on the sign. Using the exact prescribed wording is essential for regulatory compliance.

They must be posted at the entrance to any regulated area so that an employee can read the sign and take necessary precautions, such as putting on a respirator or protective suit, before they enter the potentially contaminated zone. Posting regulated area signs inside the zone is too late to prevent exposure.

Since these areas often involve chemical processing or laboratories, signs should be made of chemical-resistant aluminum or polyester laminate. These materials withstand cleaning solvents and chemical vapors without fading or degrading over time, ensuring the critical health warning remains legible for the life of the facility.

While OSHA mandates specific English wording, adding a Spanish translation is permitted and highly recommended. It ensures that all workers fully understand the severe long-term health risks involved with exposure to the carcinogens present. Clear communication is vital when dealing with invisible hazards like carcinogens.
