Customized Reflective Safety Warning Signs

Reflective Customized safety signs play a critical role to alert, warn and direct work crews and the general public. Reflective safety warning signs can be made on two types of reflective material: engineer grade and high-intensity prismatic grade film.

Do reflective custom safety signs comply with an OSHA safety sign standard?

Stock and Custom Signs are all formatted to comply with ANSI and OSHA Z535.4 codes. ANSI and OSHA created these codes for the graphic presentation of safety sign information. These codes create a standard that ensures critical information is displayed in the most direct and effective format for everyone’s safety.

Where would you use customized reflective OSHA Signage?

From public space to corporate facilities to utility companies and related infrastructure, customized safety warning signs are widely used and play a critical role. Low light environments such as utility facilities and its infrastructure are a perfect application for reflective signage.

The generation and distribution of electrical power is a vast network of facilities containing dangerous equipment and hazardous spaces to work crews and the public. An example is an electrical substation which requires many OSHA safety signs. Electrical substations transform the transmitted power from high to low voltage. Substations contain a variety of electrical equipment, all within a fenced area or in an enclosed building. These facilities and the equipment contained within are required to be marked for safety. Perimeter fence signage displays the name and ownership of the substation and can be further customized with the utility’s contact information. High Voltage signs and Do Not Climb signs alert to the dangerous high voltage inside and the deadly risk associated with climbing the fences and structures within.

Water utilities store, treat and supply our natural resource of water. These resources require protection from contamination and theft as well as warnings to water utility personnel and the general public. OSHA compliant signs include notifications of private property, video surveillance, no trespassing and associated fines and penalties. There are also hidden dangers at areas such as dams, where unexpected releases of water can cause sudden rises in water levels. Deep reservoir waters are extremely cold and dangerous to swimmers. Hidden submerged objects such as rocks and water intake structures can be a danger to swimmers and boaters. Caution warning signs can be customized to alert to these potential dangers and still conform to OSHA guidelines.

Retroreflective sheeting materials encapsulate tiny glass beads, prisms and lenses to direct the light back in the general direction of the source but with a slight variance to allow the viewer to see the reflective signage clearly. The retroreflective products allow viewers to see the sign or label from greater distances because of the intensity of the reflected light.

There are three different types of reflective materials. Reflective signs come with a minimum outdoor lifespan of 10 years:

  • Engineer Grade is the most common reflective material type.
  • High Intensity Prismatic is used for situations that require additional visibility. This material is excellent for signs that may need to be seen from an angle. These signs come with a 10-year warranty.
  • Diamond Grade is the most dynamic reflective material type. Reflectivity is twice as strong as High Intensity reflective. Visibility is equally as strong during the day and nighttime.
