Flammable Signs

For industrial environments, durable aluminum is recommended for a sign like the highly flammable sign, since aluminum flammable signs are rust-proof, chemical-resistant, and able to withstand harsh industrial conditions better than plastic or vinyl.

The difference between these signs is based on the liquid's flash point, as defined by OSHA. A liquid flagged by a hazard hydrogen flammable gas sign can ignite at lower temperatures, with a flash point below 100°F, posing a greater immediate risk than a liquid marked with a "combustible" sign, which applies to a flash point at or above 100°F.

Flammable liquid warning signs should be placed in highly visible locations where they can be seen before a person enters a hazard area. Per OSHA guidelines, this includes entrances to storage rooms, on cabinets, and near equipment that uses flammable liquids.

Custom flammable signs are available, letting you add the specific chemical name, its NFPA ratings, and any unique handling instructions required for your facility.

Yes, bilingual flammable signs are available, covering messages such as "Flammable / Inflamable" and "Flammable Materials / Materiales Inflamables." Bilingual flammable signs help ensure the warning is understood across a diverse workforce, reducing the risk of an accident caused by a language barrier.

A GHS flammable hazard pictogram follows the Globally Harmonized System of Classification and Labeling of Chemicals, using a standardized flame symbol recognized internationally rather than facility-specific wording. A standard flammable sign often pairs a signal word, such as Danger or Warning, with specific text describing the hazard, while a GHS pictogram is designed to communicate the same risk visually across different countries and languages.

Yes, glow-in-the-dark flammable signs are available for facilities that need high visibility during power outages or blackouts. Glow-in-the-dark flammable signs are especially useful in areas where standard lighting can't be guaranteed, such as stairwells or storage rooms near flammable materials.
