The enhanced visibility equipment is grouped into three types based on the foreseeable conditions of use:
Equipment is worn by users where the risk of not being seen exists only in daylight conditions. This equipment uses only the fluorescent material as an enhanced visibility component.
– Type B
Equipment is worn by users where the risk of not being seen exists only in dark conditions. This equipment uses only the retroreflective material as an enhanced visibility component.
Type B is subdivided in 3 levels, as below. The classification depends on the total area worn or replacement of the device on the user’s torso and limbs:
– Type B1 includes free-hanging retroreflective devices only; these devices are designed for movement recognition.
– Type B2 includes retroreflective devices or retroreflective material either temporarily or permanently placed on limbs only; these products are designed for movement recognition. As a minimum, the retroreflective material shall be positioned on the limbs as a separate removable device or shall be incorporated into clothing design on a permanent basis as a retroreflective element.
Type B3 includes retroreflective material placed on the torso or torso and limbs. These products are designed for form recognition, or form and movement recognition. Type B3 items shall not be a combination of permanently attached reflective material and removable reflective devices.NOTE1 Additional retroreflective or combined-performance materials can be incorporated into garments.
Equipment is worn by users where the risk of not being seen exists during daylight, twilight, and dark conditions. This equipment uses fluorescent as well as retroreflective and/or combined performance materials as enhanced visibility components.
Table 1 shows the different types.
