When should I use the Danger or Warning headers?
The correct safety signal word header is specified in the ANSI Z535 standard, and depends upon the level of seriousness that is associated with the hazardous situation to be avoided.
The color of the header must be that which is relevant to the safety signal word being used; safety red for DANGER, safety orange for WARNING, safety yellow for CAUTION, safety blue for NOTICE.
-
- DANGER indicates a hazardous situation which if not avoided will result in death or serious injury, and should be limited to the most extreme situations. The DANGER header should not be used to limit access in order to prevent property damage hazards unless personal injury appropriate to the DANGER level signal word is also involved.
-
- WARNING indicates a level of hazard which if not avoided could result in death or serious injury. The WARNING header should not be used to limit access in order to prevent property damage hazards unless personal injury appropriate to the WARNING level signal word is also involved.
-
- The CAUTION header indicates a level of hazard which if not avoided could result in minor or moderate injury.
-
- The NOTICE header is the preferred signal word to address practices not related to personal injury.

What are the most durable sign materials?
The most durable sign material is dependent on the conditions present in the application environment.
These conditions can include UV degradation from sunlight, chemicals, abrasion, temperature extremes, impact, bending, and even attractiveness to theft due to scrap value. Two of Electromark’s most durable sign materials for these conditions include fiberglass and porcelain.
Electromark’s fiberglass sign carries a 20 year warranty, and has field service history experience supplying it’s fiberglass signs for greater than 25 years with no reported failures. In addition, Electromark’s fiberglass sign offers exceptional chemical resistance, impact resistance, and cold weather performance.
Porcelain enamel signs graphics are composed of a glass-based inorganic pigment mixture stenciled onto the porcelain coated surface. Like the porcelain base coat, each color is fired in a kiln and fuses with the base coat color to become one with the sign. Unlike competitor’s signs that use more common and corrosion prone low-carbon base steel substrate, Electromark exclusively uses non-corrosive stainless steel. Electromark’s porcelain sign carries a 30 year warranty, and porcelain signs can last 50 years or longer. In addition, Electromark’s porcelain signs offer very high heat resistance (1400°F), and exceptional resistance to abrasion/scratching, chemicals, and corrosion.
