If you haven’t seen them already, you’ll soon see some changes to the ANSI/ISEA 107-2015 standard for high visibility safety apparel (HVSA). These updates will make it easier to understand a garment’s intended use, improve safety by allowing better fit, clearly identify Flame Resistant (FR) material and allow some leeway for custom logos or artwork.
- Three NEW Garment Types
Under the new ANSI/ISEA 107-2015 standard, three GarmentTypesare now associated with the different Performance Classes. The standard continues to define three performance classes (1, 2, and 3) based on the amount of visible materials and design attributes of the final configuration.
Type O– Off-Road Use (Includes Class 1)
Provides daytime and nighttime visual conspicuity enhancement for workers in occupational environments which pose struck-by hazards from moving vehicles, equipment and machinery, but which will not include exposure to traffic on public access highway right-of-ways or roadway temporary traffic control (TTC) zones.
Type R– Roadway Use & Temporary Traffic Control (Includes Classes 2 & 3)
Provides daytime and nighttime visual conspicuity enhancement for workers in occupational environments which include exposure to traffic from public access highway right-of-ways, or roadway temporary traffic control (TTC) zones, or from work vehicles and construction equipment within a roadway temporary traffic control (TTC) zone.
Type P– Public Safety (Includes Classes 2 & 3)
Provides daytime and nighttime visual conspicuity enhancement for emergency and incident responders and law enforcement personnel in occupational environments which include exposure to traffic (vehicles using the highway for purposes of travel) from public access highway right-of-ways, or roadway temporary traffic control (TTC) zones, or from work vehicles and construction equipment within a roadway temporary traffic control (TTC) zone or from equipment and vehicles within the activity area. Type P HVSA provides additional options for emergency responders, incident responders and law enforcement who have competing hazards or require access to special equipment.
- Four Classes
The Class system includes three main brackets, with additional brackets for supplemental apparel and optional accessories.
Class 1– Provides the minimum amount of high-visibility materials required to
differentiate the wearer visually from non-complex work environments where struck-by hazards will not be approaching at roadway speeds.
Class 2– Provides for the use of additional amounts of high-visibility materials, which may allow design opportunities to define the human form more effectively.
Class 3– Provides greater visibility to the wearer in both complex backgrounds and through a full range of body movements by mandatory placement of background, retroreflective and combined-performance materials on sleeves and pant legs (if present). Regardless of the area
of materials used, a sleeveless garment or vest alone is not considered Performance Class 3.
Class E– Supplementary Class E Pants, bib overalls, shorts, and gaiters are designated Class E. Class E items are not meant to be worn alone for the purposes of meeting HVSA PPE requirements. When a Class E item is worn with Performance Class 2 or Class 3, the overall classification is Performance Class 3.
Optional High-Visibility Accessories– High-visibility accessories are not intended to be used alone as personal protective equipment against struck-by hazards and such items do not contribute to the minimum areas of visible materials of the HVSA.
- A Single HVSA Standard
Originally,ANSI 107served as the primary Hi-Viz standard for both General Roadway and Public Safety hazards. The ANSI/ISEA 207standard was created to address unique issues faced by Public Safety Professionals, like uniform requirements and the need to wear radios and weapons on belts. Creating the new Garment Types allows for ANSI/ISEA 207to merge with 107under Type P – Public Safety, for one HVSA standard.
- Smaller Sizes Allowed
One of the most significant of the 2015 revisions is new design criteria that allows for smaller-sized vests. Previously, due to the minimum amount of background material required for ANSI/ISEA 107-2010, the smallest vest size that met the requirement was often too big for many people under 5’6”.
Proper fit reduces the potential of injury from catch hazards. With the ANSI/ISEA 107-2015 revision, the minimum area of background material required for the smallest size offered has been reduced by 30% for Type R Class 2 and by 25% for Type R Class 3.
- FR Labeling
Labeling requirements have changed in relation to a material’s FR performance. ANSI/ISEA 107-2015 rated garments made from polyester or any non-inherently flame-resistant fabric will require the following statement on the label:
This garment is not flame resistant as defined by ANSI/ISEA 107-2015 Section 10.5.
Any HVSA made with treated polyester material cannot be called “FR”.
A more accurate description for a synthetic material that is treated with a fire-retardant solution is Self-Extinguishing.
The purpose of this change is to eliminate any potential use of treated polyester vests in all applications with potential for Arc Flash or Flash Fire hazards. “Self-Extinguishing” vests are only intended for incidental flammable hazards that may involve potential for exposure to welding/grinding sparks or incidental open flame.
- Balance of Design & Logo Allowances
Logo allowances have been incorporated into the standard which allows for a company’s logo to be added without being required to deduct the background area of the logo. The new revision for balance requirement insures that the protective properties of HVSA are not compromised by design or style objectives.
To insure color blocking or other design criteria do not reduce the protection provided from any one direction, HVSA garments must have at least 40% of the minimum required amount of both background and reflective material on either front or back of garment. For example, a Type R Class 2 garment requires 201 square inches of reflective material. The minimum amount of reflective material on the front or back of the garment must exceed 80.4 square inches. This requirement maintains the integrity of the vest, its form and function, above design or style objectives.
An Intuitive Standard for Increased Safety
The new ANSI/ISEA 107-2015 standard includes easier to understand garment types and classes, clearly defines FR labeling, allows smaller sizes, includes allowances for logo artwork and creates a single HVSA standard. The goal is simply to make it easier to choose the right HVSA for the job to reduce accidents and injuries, keeping you as safe as possible.
