Welcome to the Westex Blog

Where we share our perspective on current trends, best practices, and the future of FR safety.

The Difference Between Inherent and Treated Fabrics, and What it Means for Your Safety Program

The FR industry certainly has its share of jargon, and especially when that jargon has little scientific background, it can lead to muddled and complicated decisions. In our white paper, What’s in a Word: Inherent Fabric, Treated Fabric, and What They Mean in the World of Flame Resistant Fabrics, we discuss two major industry terms—“inherent” and “treated”—and cover how these flame resistant (FR), arc-rated (AR) fabric classifications have evolved over time.

5 Reasons to Implement FR/AR PPE Training

Flame resistant (FR), arc-rated (AR) personal protective equipment (PPE) is an important part of establishing a well-rounded safety program. Before donning their FR/AR PPE, however, employees need to be educated about their PPE garments so they can properly guard themselves against workplace hazards such as arc flashes or flash fires. Understanding how to wear PPE, what their PPE will help protect against, and how to care for their PPE is essential for end users’ safety. We rounded up five important reasons to train employees about their PPE.

Elevating Performance Standards: How Westex by Milliken is Raising the Bar on Testing Protocols

Part of designing reputable protective fabrics is ensuring they provide certified, consistent results both in the lab and in the field—otherwise, end users may be at risk. Flame resistant (FR), arc-rated (AR) fabrics incorporated into personal protective equipment (PPE) act as a final layer of defense against hazards like arc flashes and flash fires, so these fabrics must perform. But how does a company like Westex by Milliken assess performance? We sat down with James Cliver, senior development engineer for Westex by Milliken, to learn more about how FR/AR fabrics are tested and why standard testing protocols are a crucial indicator of performance.

Tailored to Women: The Case for Utilizing Women-Specific FR/AR Garments in the Workplace

Until recently, flame resistant (FR), arc-rated (AR) garments were one size fits all—meaning both men and women wore the same styles. Women in the oil and gas and electrical industries thus donned ill-fitting FR/AR garments day in and day out, because these garments were largely constructed with men in mind. Typically, women have to find FR/AR garments that mostly fit then adjust them throughout the day as they shift out of place.

The Last Line of Defense: Four Ways Daily Wear FR/AR PPE Improves Safety Programs

For worksites where short-term thermal hazards are present, flame resistant (FR), arc-rated (AR) personal protective equipment (PPE) is a critical component in providing protection in the event of an unexpected incident, like arc flash, flash fire, or dust combustion. While key, however, it is important to note that when designing your safety program, daily wear FR/AR PPE is one of many parts of a comprehensive thermal hazard mitigation program.

Inhärent Flammhemmend / Flammgeschützt Stoff

Inhärent vs. Behandelt: Kommt es wirklich darauf an?

In der Vergangenheit ließen sich die flammhemmenden Eigenschaften von flammhemmenden Stoffen in zwei Kategorien einteilen: Inhärent und behandelt (oder ausgerüstet). Es war einmal eine relevante Unterscheidung. Dies bedeutete den Unterschied zwischen dauerhaften und nicht dauerhaften flammhemmenden Eigenschaften. Diese Begriffe enthielten jedoch keine Informationen mehr für Sicherheitsmanager, die bereits 1987 flammhemmende Stoffe bewerten wollten.
