Full Description

1.1 This guide covers the physical principles and variables involved in the performance and selection of high visibility materials for individual safety.

1.2 It is the purpose of this guide to examine the principles on which future standards relating to individual safety may be used. However, this guide does not set minimum standards for the properties of high visibility materials.

1.3 In reviewing the principles contained in this guide, it must be remembered that there are numerous factors adversely affecting visibility and safety (for example, rain, snow, road grime, alcohol, advanced age, drugs, fatigue, inattention, headlamp misalignment or breakage) that must be taken into account when dealing with actual safety requirements.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
