Do You Work in High-Risk Environments Like Construction Sites, Warehouses, or Airport Runways?

In any workplace where a moment of inattention could lead to serious accidents, safety must always come first. That’s why high-visibility (hi-vis) clothing is not just recommended—it’s essential.

Designed with fluorescent colors and reflective materials, hi-vis garments are critical safety tools that enhance a worker’s visibility, especially in low-light, high-traffic, or hazardous environments. These garments aren’t about style—they’re about saving lives.

Whether it’s a reflective work jacket, hi-vis overalls, fluorescent pants, safety armbands, or warning flags, these items help ensure you're clearly visible to others—especially drivers and machine operators—reducing the risk of accidents.

But how do you know if the gear you’re buying is truly effective?

Here are 9 essential things you need to know about high-visibility safety clothing to make sure you're choosing the right protection for your job.

The 9 Key Factors to Consider When Choosing High-Visibility Clothing

High-visibility clothing—commonly known as hi-vis apparel—is specifically designed to increase a worker’s visibility in low-light or visually obstructed environments. Whether you’re working around moving vehicles, heavy equipment, or hazardous conditions, wearing the right hi-vis gear can make all the difference in staying safe.

To ensure you're getting the most out of your high-visibility garments, consider the following nine important factors:

1. Lighting and Weather Conditions

Do you work at night, in dimly lit areas, or outdoors during unpredictable weather? Visibility is crucial in these settings. To maximize safety:

Choose hi-vis clothing that covers the full body for 360-degree visibility.

In fog, rain, snow, or at dawn/dusk, opt for high-visibility outerwear such as waterproof safety jackets or reflective fleece layers.

Avoid covering hi-vis vests with non-reflective raincoats, as this reduces their effectiveness. Instead, select garments specifically designed to maintain visibility in poor weather.

2. Workplace Hazards and Job Tasks

Before deciding what type of hi-vis clothing you need, assess the specific risks in your work environment:

Do your tasks involve hazardous materials or moving machinery?

Are you in the vicinity of rolling stock or vehicles?

Are you exposed to extreme heat or open flames?

Do you work in cluttered or obstacle-prone areas?

Is the lighting sufficient, or is it inconsistent?

Are you sheltered from or exposed to the elements?

Do you work in traffic zones where vehicle speed is a concern?

Do your surroundings demand quick reaction times?

Are there distractions that might impair awareness?

Answering these questions will help determine the level and type of visibility protection required. For instance, environments with moving traffic often call for ANSI Class 2 or Class 3 garments to meet safety standards.

Conclusion: Visibility Is a Lifesaver

High-visibility clothing isn’t one-size-fits-all. The right garment should match your work environment, task, and level of risk exposure. Whether you’re in construction, logistics, aviation, or public works, understanding these key factors can help you select the most effective protective gear—and stay safe on the job.
