The "ANSI/ISEA 107 High-visibility safety clothing and hat devices" standard developed by the American National Standards Institute / International Safety Equipment Association (ANSI/ISEA) describes the performance requirements for high-visibility safety clothing and hat personal protective equipment.
For the purposes of this standard, clothing refers to clothing and personal protective equipment. This type of clothing is designed to provide visibility to the user in all kinds of light conditions during the day and in dangerous situations illuminated by vehicle headlights in the dark.
This standard covers performance requirements for color, back reflection and minimum fields, as well as the recommended configuration of materials. Back reflection occurs when a surface reflects a majority of the directed beam back to its source. Reflecting materials appear very bright to observers closest to the light source.
The standard in question also includes performance requirements regarding the physical properties of the background materials used in the construction of high-visibility safety clothing and hats.
Test methods are provided in the ANSI/ISEA 107 standard to help maintain a minimum level of visibility when garments are subjected to ongoing maintenance procedures.
High-visibility safety clothing is clothing used to increase the visibility of employees and enable other people to see them better. Often, high-visibility clothing is used to alert drivers and other vehicle operators to the presence of a worker, especially in low-light and dark conditions.
The ANSI/ISEA 107 standard briefly specifies performance requirements for conspicuous materials to be used in high-visibility safety clothing and the minimum amount of background, backscatter, and combined performance materials, colors, and placement of materials for garments and accessories used to enhance visibility and safety.
High-visibility safety clothing is essential for those working in low light and poor visibility conditions, especially those working around moving vehicles such as trucks or self-powered forklifts and excavators. Highly visible products enable employees to be seen from further away and react accordingly, which increases occupational safety. The human eye responds best to large, contrasting, bright or moving objects.
In short, this American national standard for high-visibility safety clothing and accessories is a standard that establishes requirements for clothing and accessories used by workers to visually reveal their presence. Since its publication, this standard has been recognized by federal, state and local authorities, as well as private sector organizations, and its compliance has become mandatory.
Construction, maintenance, service, emergency responders, airport ramp personnel, and many categories of field workers in general are routinely exposed to potential hazards due to their low visibility while on the job. This standard provides guidelines for the selection and use of high-visibility safety clothing, such as shirts, raincoats, outerwear, and safety vests, to help increase workers' visibility during the day, in low-light conditions, and at night.
The last update of this standard was made in 2020 with the following title: “ANSI/ISEA 107 High visibility safety clothing”. After this update, the standard focuses on:
Employees' high-visibility safety clothing and its bright colors limit work injuries and deaths. Thanks to this outfit, which attracts attention with its bright color, it is easier to notice and stop the employee or prevent an accident. Bright colors with retro-reflective material are more helpful during dawn, dusk, or night hours when bright colors cannot be easily seen. With a light source, such as the headlights of a vehicle or machine, retroreflective material attracts attention by reflecting light back.
