Hot Surface Signs & Warning Labels FAQs
What temperature makes a surface require a hot surface warning?
ANSI/ASTM standards suggest warning labels for surfaces that can cause a burn on contact, generally at temperatures above 111°F (44°C) for brief contact exposure. OSHA's general duty clause applies when hot surfaces present a recognized hazard.
Should I use Caution or Warning for a hot surface sign?
Use CAUTION for surfaces that could cause minor burns on brief contact. Use WARNING for surfaces hot enough to cause serious burns or injury with even momentary contact. Use DANGER for immediately life-threatening burn hazards such as steam pipes at high pressure.
Are hot surface labels available for curved pipes?
Yes. We offer flexible adhesive polyester labels and pipe wrap labels specifically designed to adhere to curved pipe surfaces.
What material is best for a hot surface label near heat sources?
Self-adhesive polyester or aluminum foil labels are the best choice for surfaces near heat sources, as they can withstand high ambient temperatures without curling or delaminating.
Can hot surface signs include a temperature rating?
Yes. Custom signs can include specific temperature warnings such as 'Caution - Surface Temperature May Exceed 300°F' for process-specific applications.
