Understanding ANSI 107-2015

The American National Standard for High-Visibility Safety Apparel and Accessories is a standard established by the American National Standards Institute, Inc., providing guidelines for the use of high-visibility safety apparel (shirts, rainwear, outerwear, safety vests, headwear, etc.) and gear to make it easier to see workers who are routinely exposed to potential injury from low visibility situations. No matter if they’re working during the day, night, or in low-light conditions, these standards were put in place to help keep those at work safe.

The Most Recent ANSI Update

Most recently updated in 2015, the ANSI 107-2015 standards introduced three classifications that are directly applicable to construction, utility workers, or other businesses that outfit their teams in safety gear. These safety apparel classifications, called “Types”, quickly designate the minimum amount of extra visibility needed to keep employees safe in specific environments. The Types divide minimum visibility requirements for Off-Road (Type O) and On-Road (Type R) applications, understanding that in complex, moving, and dangerous environments additional high-visibility features are necessary.

The revisions also removed previous minimum area requirements for garments. This means clothing in smaller-sizes is now compliant with ANSI standards, allowing team members to wear correctly sized apparel and avoid loose/hanging clothing that could create potential safety hazards. This is most applicable for safety vests or t-shirts, where smaller sizes were previously not available.

General descriptions of each Type and Classification are outlined below with details on what situations would require them to be used.

Type O Class 1

Off Road Applications – for use in environments where there are struck-by hazards from moving vehicles, equipment and machinery not operating on public access rights of way or temporary traffic control zones.

Who Needs It?

  • Parking Attendants
  • Service Location Workers
  • Warehouse Employees
  • Oil & Gas Extraction Teams
  • Refinery Workers
  • Mining Employees

Type R Class 2

Roadway Applications – for personnel exposed to vehicle traffic on a public access right of way or roadway temporary traffic control zones. Designed with greater amounts of hi-visibility materials to help distinguish humans from inanimate object.

Who Needs It?

  • Forestry Operations
  • Ship Cargo Loading
  • Roadway Construction
  • Utility and Highway Workers
  • School Crossing Guards
  • Delivery Vehicle Drivers
  • High-Volume Parking/Toll Gate Attendants
  • Airport Ground Crews
  • Trash/Recycling Collection and Operations

Type R Class 3

Roadway Applications – for personnel that require an even higher level of visibility in high-traffic environments. Class 3 garments mandate an even higher standard of visibility for workers in moving, complex background.

Who Needs It?

  • Roadway construction personnel and flaggers
  • Utility Workers
  • Survey Crews
