Apparel Supply Equips Offaly Fire & Rescue with Twin System® Firefighting Suits

Offaly Fire and Rescue have chosen Apparel Supply as their trusted supplier for high-quality fire suits. The Fire & Rescue Service unwavering commitment to safety and performance has led them to opt for Apparel Supply’s Twin System® Firefighting suit.

The Twin System suit is a structural firefighting suit certified to EN 469 Level 2, surpassing all required test requirements in EN 469. Twin System® employs patented weaving technology, where the Kevlar content is woven into the material’s backside in a grid formation. This construction enhances mechanical performance without altering the suit’s appearance or weight.

The patented PTFE moisture barrier offers the highest waterproof and breathable performance available for fire suits. The thermal barrier, Twin Spacer, is designed to provide maximum thermal insulation through an air gap system. Twin Spacer is a lightweight two-layer fabric that offers excellent thermal insulation via an air circulation system.

The Twin System assembly provides optimal protection and comfort for firefighters, reducing thermal stress in normal working conditions (low heat flux) and allowing for quick drying without significant changes in appearance, such as holes or pilling.

Recognized for their reliability and protection, these suits are designed with the latest advancements in fire-resistant technology, ensuring Offaly Fire Station’s dedicated first responders experience the utmost in safety and comfort. This partnership underscores Apparel Supply’s mission to provide dependable safety gear to those on the front lines, ensuring they have the quality equipment needed to carry out their vital work. We are proud to support Offaly Fire Station in their mission to keep the community safe and salute their dedication to maintaining high safety standards.

What Is An Arc Flash?

An arc flash is a sudden release of electrical energy that occurs when current jumps across a gap between two conductors or from a conductor to a ground. The arc flash generates an intense burst of heat and light that can cause serious injuries, damage to equipment, and fires.

Arc flashes can occur in a wide range of electrical systems and equipment, including switchgear, transformers, motors, and other high-voltage components. They can be caused by a variety of factors, including equipment failure, human error, or a short circuit.

The intense heat generated by an arc flash can cause severe burns, as well as ignite clothing and other materials in the surrounding area, leading to secondary fires. The bright light from the arc flash can also cause temporary or permanent vision damage.

To prevent arc flash incidents, it’s important to follow proper electrical safety procedures, including wearing appropriate personal protective equipment (PPE), de-energizing equipment before working on it, and maintaining a safe distance from energized equipment.

Understanding Arc Ratings and Calories

Now that you understand FR clothing is tested and given an arc rating, you know that the arc rating measures the amount of heat the flame resistant fabric blocks when exposed to electric arc. The arc rating is the number of calories that the garment is expected to “absorb” if exposed to an electric arc. Arc rating is, in essence, the level of protection provided to you, the wearer.

Calorie is the unit of measure of the heat energy of an arc flash and the protective level of FR clothing. The bigger the calorie number, the greater the heat energy level of arc flash and the greater the protective level of the clothing. You will be protected from an electric arc if your clothing has a higher calorie arc rating than the calories of heat generated by the arc.

While it does not matter if the fabric has an Ebt,  ATPV and or ELIM value, it is important to pay attention to the calorie level the fabric can support* (as expressed in cal/cm2)
