Fluorescent material will appear brighter than the same coloured non-fluorescent material, especially under low natural light (e.g., cloud cover, fog, dusk, dawn, etc.). This material only functions where there is a source of natural sunlight. High-visibility apparel is considered to be personal protective equipment, and can be used in addition to other controls.Ĭan I add a logo or name tag to the High-Visibility Apparel?įluorescent material takes a portion of invisible ultraviolet light from sunlight, and through special pigments, sends it back to the viewer as more visible light. It is important to eliminate or reduce the hazards using engineering (e.g., physical barriers) and administrative controls (e.g., work during daylight hours). Once the hazards are identified, the employer can select appropriate controls.

The sightlines of mobile equipment and vehicle operators, especially when vehicles are operated in reverse.

Any distractions that could draw workers attention away from hazards.

Current controls (e.g., engineering controls such as barricades or administrative control such as training).

Factors that affect warning distances and times, such as the volume of traffic, the size of vehicles, their potential speeds, the ability to stop quickly, and surface conditions.

Lighting conditions and how the natural light might be affected by changing weather (e.g., sunlight, overcast sky, fog, rain, or snow).

How long the worker is exposed to various traffic hazards, including traffic speeds.

The workplace environment and the background workers must be seen in (e.g., is the visual area behind the workers simple, complex, urban, rural, highway, filled with equipment, cluttered).Work conditions, such as indoor or outdoor work, temperature, work rates, traffic flow, traffic volume, visibility, etc.Are there industry specifications or good practices?.

Do workers need to be visually identifiable from others in the area?.

Are workers controlling traffic or interacting with the public?.

Do workers and mobile equipment need to interact?.

When doing a hazard assessment where HVSA might be required, be sure to consider: For more information about risk assessments, please see the OSH Answers document Risk Assessment. This assessment helps determine the risk to workers of being hit by moving vehicles and the environmental conditions under which work is performed. The CSA Standard recommends that a hazard assessment be carried out on each job site to evaluate the workplace or work site for known or potential hazards a worker can encounter while performing a job or task. For example, certain tasks may require specific apparel. Before selecting any high-visibility safety apparel, always confirm the legislative requirements for your jurisdiction.
