The First Step: Evaluate Hazards in the Work Zone
Before selecting Personal Protective Equipment (PPE), it is critical to evaluate visibility hazards in the work environment. Consider moving vehicles or equipment, traffic exposure, vehicle speeds, lighting conditions, and background complexity. At Delta Plus, we know reliable protection starts with understanding these risks so safety managers can select the appropriate garment Type and Class.
Understanding Garment Types: Occupational, Roadway & Public Safety
High-visibility garments are categorized by Type based on the work environment. Type O, Class 1 is intended for occupational environments where workers are not exposed to roadway traffic but may encounter moving vehicles or equipment. Type R, Classes 2 and 3 are designed for workers exposed to roadway traffic, while Type P, Classes 2 and 3 are intended for public safety and emergency response personnel.
Navigating Classes 1, 2, and 3
Performance Class reflects the level of visibility needed for the hazard. Class 1 applies to Type O environments. Classes 2 and 3 provide greater conspicuity for roadway and public-safety applications, with Class 3 offering the highest level of visibility for more complex environments, increased traffic exposure, or conditions where workers need to be recognized more readily.
Trust Delta Plus to help protect workers from head to toe. By understanding workplace hazards and matching the appropriate Type and Class, you can confidently outfit your workforce with high-performance HI-Viz gear designed to balance visibility, comfort, and performance.
