Temperature Hazard Signs for Hot Surfaces, Extreme Heat, and Cold Conditions

Temperature hazard signs warn people before they contact hot surfaces or enter areas with potentially harmful heat or cold. Burns from hot piping, ovens, process equipment and steam lines happen in an instant, and cold environments like freezers and cryogenic storage carry their own contact and exposure risks. Wholesale Customize Labels's temperature signs use ISO-standardized symbols, including the hot surface symbol W017 in ISO 7010, in the latest ANSI Z535.2 formats, so the hazard registers at a glance.

Choosing the Right Sign for Heat and Cold Hazards

• Hot surface signs for equipment, piping, and machinery that stays hot in operation
• Extreme heat area signs for process zones, boiler rooms and summer-exposed work areas
• Cold warning signs for freezers, cold rooms and cryogenic storage

Match the signal word to the severity: burns that would be minor or moderate call for a caution sign, while contact that could cause serious injury calls for a warning sign. For burn hazards on equipment itself see our burn hazard safety labels, and for tag-style warnings, see our burn hazard safety signs and tags.
