Heat and Flame Protective Wear A promise is only
as good as the person who makes it. That’s why a promise backed by scientific tests always rules the day. Especially when your safety – and in certain situations even your life – is at stake. That’s also why we put our high-risk environment (Category III) products through thorough tests, using test methods such as the open arc and box tests. But what do these tests measure? What’s the difference between them? And how are they carried out? HAF Heat Attenuation Factor (HAF) is a measurement of the percentage of energy that is blocked by the material or material system. Even though a fabric may be 100% flame resistant, this does not mean it will block all of the heat it’s exposed to. A HAF of 85% means that it will block 85% of the heat the fabric is exposed to. This is in the case of a short burst of arc-flash heat – typically less than one second. In the event of prolonged heat exposure, the HAF would be much lower. A pioneer in testing protective wear Snickers Workwear offers great expertise and many years of experience in protective clothing. Our experts have led the development of protective clothing for the energy and power industries for many years. In fact, they were the first to initiate testing for protection against the thermal hazards of an electric arc when developing flame-proof protective wear. It goes without saying that our garments meet current standards and certifications as a minimum. 11
