ANSI (American National Standards Institute)
is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States.
MANDATES that ALL workers in federally-assisted highway right of ways wearing headgear have a minimum of 78 square inches of “background material” (which would include the safety orange or lime-green or safety red color) AND a minimum of 10 square inches of retroreflective Level 2 material.& ; Some states require more: Washington State requires 12 square inches; Colorado requires 23.5 to 25 square inches for nighttime.& ; But the 107-2010 is a national requirement for both FHWA and OSHA.
When a garment can be exposed to an Arc Flash (see below) the fabrics and resistance to combustion are rated, “normally expressed in cal/cm2 (or small calories of heat energy per square centimeter). The tests for determining arc rating are defined in ASTM F1506 Standard Performance Specification for Flame Resistant Textile Materials for Wearing Apparel for Use by Electrical Workers Exposed to Momentary Electric Arc and Related Thermal Hazards.”
- Arc Flash
- Flame Resistance (FR)
- Flame Retardant
- IEEE (Institute of Electrical and Electronics Engineers)
An association dedicated to advancing innovation and technological excellence for the benefit of humanity is the world’s largest technical professional society. It is designed to serve professionals involved in all aspects of the electrical, electronic, and computing fields and related areas of science and technology that underlie modern civilization.
IEEE-SA (Standards Association)
Publishes standards that establish specifications and procedures designed to ensure the reliability of the materials, products, methods, and/or services people use every day. Standards address a range of issues, including but not limited to various protocols that help ensure product functionality and compatibility, facilitate interoperability and support consumer safety and public health.
This includes the safety of employees and contractors working in those technological fields. They define safety standards for garments that may be in proximity to ignition sources, such as arc flash.

MUTCD & (Manual of Uniform Traffic Control Devices)
This is a Federal Highway published manual for ALL road construction companies and municipalities to live by when working on federally funded roads.
National Electric Safety Code (NESC)
titled Standard for Electrical Safety in the Workplace, is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for its sponsorship of the National Electrical Code (NFPA 70).
Poly (short for polymer) and -esters (chemical compounds) are formed from large molecules arranged into repeating increments like a chain. In textiles, polyester is formed into threads and woven into the fabric, Polyester’s structure and properties give it superior durability, natural wicking, and color retention.
Written as retroreflective or retro-reflective, this term is applied to portions of High Visibility Safety garments that increase nighttime visibility by reflecting light back in the direction it came from.
When light strikes a reflective surface (mirror) at an extreme angle, the light travels away from its source. A retroreflective surface bounces light back to its source regardless of the angle. A garment with retroreflective material bounces light back at its source (headlights) instead of scattering it away in the opposite direction. A vehicle operator would see more light bouncing back and perceive a human figure.
Vectorize (Convert to Vector Graphics or Line Art)
Graphic Artists use 2 types of programs to create images.& ;The first uses rectangular dots called pixels. This is Rastor Graphics.& ;The second uses geometry and mathmatical equations to create images. The benefit of Vector Graphics is the shapes are precisely defined using geometric lines, creating smooth edges for the Computer Controlled Cutter. Those lines, called paths, give the computer a roadmap for the blade to follow. The result is a clean image with graceful lines, not the jagged, stair-stepped look a raster image would output.
