Caution & Danger Signs

Caution and danger signs are essential safety tools used to warn occupants, workers, and visitors about potential hazards in buildings, workplaces, and construction sites. Caution signs are typically used to alert people to potential risks that may cause minor or moderate injury, such as wet floors, low ceilings, or restricted areas. Danger signs, on the other hand, are reserved for the most serious hazards where failure to comply could result in severe injury or death—for example, high-voltage areas, boiler rooms, chemical storage, or elevator hoistways. By posting these signs in visible locations, property owners and managers protect lives, reduce accidents, and ensure compliance with OSHA, FDNY, NFPA, and local safety codes.

These signs are usually manufactured in high-contrast colors like yellow and black for caution and red, black, and white for danger, following ANSI and OSHA standards. They are available in durable aluminum, plastic, or photoluminescent (glow-in-the-dark) materials for visibility in low light or power outages. Common examples include “Caution – Watch Your Step,” “Caution – Wet Floor,” “Danger – High Voltage,” “Danger – Do Not Enter,” and “Danger – Confined Space.” Installing caution and danger signs not only prevents accidents but also demonstrates a property owner’s commitment to safety and regulatory compliance.
