Danger sign for a confined space, indicating restricted entry and the need to contact security for permission. Found in industrial settings. — This sign indicates a confined space, a location with limited entry and exit points that may contain hazardous atmospheres. Such spaces, common in industrial settings like factories, storage tanks, and utility tunnels, require strict safety protocols to prevent accidents. The "Danger" warning and the instruction to "Do not enter" without contacting security highlight the potential risks, which can include oxygen deficiency, toxic gases, or engulfment hazards. Adherence to these warnings is crucial for worker safety and regulatory compliance.

The sign also denotes the presence of flammable liquids, highlighting the need for careful handling and storage protocols in industrial or laboratory settings.

Smokey Bear fire danger warning sign displaying "Extreme Fire Danger" along a forested roadside in Minnesota's Iron Range. — Smokey Bear has appeared on fire danger warning signs since the U.S. Forest Service launched the prevention campaign in 1944, later adopting the "Only you can prevent forest fires." Signs like this one use an adjustable gauge to alert travelers to current wildfire risk levels, ranging from low to extreme. Minnesota's Iron Range, a region of dense forest and dry underbrush north of Babbitt, sees these postings along roadsides during periods of low rainfall.
